I've finally gathered all the knowledge about Kunlun Tongtai today! This article addresses common technical issues and provides a concise explanation of the solutions for each problem.
Network version issues
1. How are points calculated in MCGS configuration software?
In the real-time database, all added variables, except for the four system internal variables, are counted as software points. You can view the MCGS point information by clicking "Tools - Use Count Check".
2. How is the number of web-based clients calculated?
This refers to the number of computers on the client side simultaneously using Internet Explorer to browse the MCGS web version server.
3. During installation, an error message appears stating that the parallel port dongle driver cannot be installed?
If the computer does not have a parallel port or the parallel port is occupied during the installation of the configuration software, this prompt box will appear. Click "Skip this step" to continue the installation.
4. How do I install the English version of MCGS network version software?
Installing the Chinese version of MCGS Network Edition software on an English operating system will display the English interface. However, since some plug-ins do not support English, garbled characters may appear when adding plug-ins, but this will not affect normal use and operation.
Note: The embedded configuration environment does not currently support the English version.
5. What types of dongles are there?
The MCGS general version and network version support two types of dongles: parallel port and USB. They are also available in different point counts: 64 points, 128 points, 256 points, 512 points, 1024 points, and unlimited points.
6. Cannot detect the dongle?
The following aspects can be considered:
(1) Have other dongles been locked through the security management under the "Tools" menu?
(2) Is a printer connected to the parallel port? If a printer is connected, the BIOS parallel port mode needs to be set to ECP+EPP.
(3) Whether the software version is consistent with the dongle version;
(4) To check if the parallel port is damaged, the dongle can be tested on the parallel port of another machine.
(5) Whether the dongle driver is damaged can be tested by reinstalling the driver from the CD;
(6) Scan for and remove viruses. If the computer has a virus, the dongle will not be detected.
(7) Check if the dongle connector is loose;
(8) Reinstall MCGS software;
(9) Whether a project operation period has been set.
7. When opening the project, a message appears stating that the filename cannot contain spaces.
For MCGS network and embedded versions 6.5 (and earlier), the project name and the project path must not contain spaces; otherwise, the project will not open correctly. For example, if the project is located on the desktop, but the full desktop path is C:\Documents and Settings\Administrator\Desktop, where Documents and Settings contains spaces, the project will not open correctly.
Note: The embedded version 6.8 project (with the complete project name excluding spaces) can be opened normally when placed on the desktop.
8. How to implement the startup and operation process?
(1) Delete the executable program: D:\MCGS\Program\Mcgs
Set.exe and its corresponding desktop shortcut icon;
(2) Delete the program group created during MCGS system installation: Start All Programs MCGS Configuration Software General Version MCGS Configuration Environment;
(3) Send D:MCGSProgrammcgsrun.exe to the desktop as a shortcut, right-click and select Properties, add the following content to the Target of the shortcut: +space + project path + project name;
(4) Add the shortcut of mcgsrun.exe to "Start All Programs Startup" so that the project can be run when the computer is turned on.
9. How do I view the software's running history?
Locate the installation directory of the universal version, for example, if it is installed on drive D, find D:\MCGS\Programdaemon.log. This file records information related to the software's operation.
10. How to disable hotkeys?
In the project, simply call the function !DisableCtrlAltDel(). The function means to disable the functionality of the hotkey Ctrl+Alt+Del.
Note: This function is invalid in the web client and under the WIN98 operating system.
11. Meaning of time points in saved data browsing
This refers to defining yesterday and today according to one's own needs, specifically from which point in time, or month, etc.
12. Why can't the historical table display the extracted data?
(1) First extract the data, then use the historical table to see if the data storage period is set and if the data connection is correct. When using the data storage to extract the data, the time interval and extraction interval should be set reasonably, otherwise the data cannot be extracted normally.
(2) Check if the data source and storage target settings are correct. After the time setting is reasonable, it needs to run for a period of time before it can be displayed after there is data in the xxx.mdb database.
13. How to save data to an SQL database?
(1) General version: Extract the saved data into SQL through the data extraction component: Select the ACCESS database file automatically generated by the project as the data source, and select the ODBC database as the data output. Select the SQL database (first create the database and data table in SQL Server).
(2) Network version: Directly select the SQL database as the database to save in the "Database Connection Settings" under the File menu.
14. Can MCGS access Oracle data?
Yes, provided that the Oracle client software is successfully installed.
15. Why is the online version of the project slow to run and exit?
MCGS software comes with an Access database. Access databases are inherently small; database files exceeding 50MB can cause database crashes and slow down project operation if the amount of data stored on disk becomes too large. It is recommended to use an SQL database to store data or to perform regular data deletion.
16. What should be noted when browsing the web version of a project using Internet Explorer?
(1) Local Area Network (LAN) Internal IP Browsing Network Version Project:
The default port number for A.MCGS network version is 80. Generally, as long as the client machine can directly ping the IP address of the machine running the network version, you can directly browse it by entering the IP address of the network version server in the IE bar on the client machine.
B. If port 80 is bound to another address, you can set a different port number through the "HTTP Parameters" property under the "Main Control Window". In this way, you will need to add the port number when browsing in IE.
(2) To access a PC running a network version within a local area network (LAN) via the external network, first map the port bound to the network version running on the internal network to the public network, and then map port 1966 of the PC to the external network. A brief explanation is given using ADSL dial-up internet access as an example:
Install the PeanutShell software on the server and enter the registered free domain name, such as mcgsjn.givp.net
Configure the router (such as TP-LINK):
A enters the dynamic DNS settings and binds the domain name;
In "Forwarding Rules", navigate to "Virtual Server" and configure as follows:
ID service port IP address protocol status
TCP 13100200.200.200.11 is now active.
21966200.200.200.11 TCP effective
Run the network version of the project on your PC using C. Enter the address http://mcgsjn.givp.net:3100/defaul.htm in the IE browser bar to access it from the internet.
17. How should damage to the project be repaired?
(1) You need to install the Access database in the Office software;
(2) Close the configuration project, right-click the project, open with/select program/Microsoft Office Access, and click OK;
(3) Prompt: Convert/Open Database, select Open Database (Note: Do not select Convert Database, the converted project will not be recognized), a security warning will appear, select Open;
(4) After opening the ACCESS database, select Tools/Database Utilities/Compress and Repair Database from the menu to repair the project;
(5) If the above methods cannot repair the project, it means that the project is seriously damaged and needs to be reconfigured.
18. How to achieve landscape printing?
In the extended properties settings of the user window, change the "Window View Size" of the print window to the size of the print paper and select landscape printing.
19. Can script-driven systems be used in the general version?
Yes, but you'll need to use the general-purpose customized environment. You can download the customized environment from the "Download Center - Customized Versions" section at www.mcgs.com.cn. The script-driven development toolkit includes a network-compatible customized environment.
Embedded version issues
20. Does the TPC project runtime environment automatically restart?
If the CPU usage reaches 99% during project execution, the runtime environment will automatically exit and then restart.
High CPU utilization may be caused by factors such as a large number of bitmaps, numerous scripts within the loop strategy, and short loop cycles.
21. How to exit a TPC project after 30 minutes of operation?
(1) The property settings display "Running is not authorized", which means that the registration code is lost and needs to be regenerated;
(2) The property settings display "Configuration not authorized" indicates that the dongle is not plugged in to download the project. When the old TPC downloads the project, the host computer needs to plug in the dongle.
22. How do I install it using the registration code?
(1) Installation on host computer: Download configuration - advanced operation - update registration code, select the registration code file to install;
(2) Installation on the lower-level machine: Copy the registration code to a USB flash drive, plug it into the TPC USB port, and install it in the TPC's boot properties - system maintenance.
23. Why does the download process prompt a version mismatch?
(1) If it is an already running project, change the host computer environment to avoid compatibility issues between the screen and the new environment;
(2) If it is a new project, use the standard TPC release and it is recommended to automatically update the environment in the screen through the wizard.
24. How to change the environment in TPC?
(1) Click "Advanced Operations" during download to update the lower-level machine's operating environment;
(2) Copy the CeSvr.armv4 and mcgsce.armv4 files to a USB drive, and change their extensions to .exe. Replace "My Computer HardDiskCeSvr.exe" with CeSvr.exe, and replace "My Computer HardDiskkmcgsbinmcgsce.exe" with mcgsce.exe.
And the file "My Computer HardDiskackupmcgsce.exe".
25. Why are adding/deleting members in a group object not working?
Click "Tools - Use Count Check" in the menu bar to refresh the members in the group object.
26. How can data be saved in less than 1 second?
Set the save period in the save properties of the group object to 0 seconds, and call the !savedate() function in the loop strategy to use the time of the loop strategy to achieve periodic saving (the loop strategy time can be set to less than 1 second).
27. How to export historical data saved in TPC?
It is recommended to use the !ExportHisDataToCSV() function to export data. For specific function usage, please refer to the MCGS help documentation.
28. Why isn't the historical table data being refreshed?
In MCGS, the history table in the window is not refreshed automatically. The history table only accesses the database to read data when its window is open, and then does not access the database again. You can refresh the window by executing the window name.Refresh() function in the loop strategy window or the loop script of the window to access and read the database, so as to refresh the data in the history table in real time.
29. Why are historical data not displayed in the historical tables?
(1) Confirm whether the group object has been saved;
(2) Whether the window is refreshed in real time;
(3) Check if there is no variable connection in the display properties.
30. How to change the upper and lower limits of alarms during engineering operation?
The !SetAlmValue() function can be used in the loop strategy to modify the upper and lower limits of alarms during project runtime. For specific function applications, please refer to the MCGS help documentation.
31. Why are historical alarms not displayed?
(1) The "Automatically save generated alarm information" option is not selected in the property settings of the alarm data object;
(2) The alarm data has not reached the upper/lower limit of the alarm value;
(3) The group object is not selected with “MCGS_ALARM”.
32. Real-time alarm not displayed.
(1) The alarm data has not reached the upper/lower limit of the alarm value;
(2) No alarm is set in the alarm variable attribute settings.
33. How much space does alarm data occupy in TPC?
The system alarm group MCGS_AlarmInfo occupies a fixed space of 1M.
34. How is the disk space occupied by stored data calculated in TPC?
The data is saved in units of group objects. The storage space is the space occupied by all group object members plus the 8 bytes required for time storage.
Numeric type: 4 bytes; Switch type: 4 bytes; Character type: character length + 4 bytes.
35. How do I change the size of the on-screen keyboard in TPC?
Use the !SetNumPanelSize(Type, Size) function. For specific function usage, please refer to the MCGS help documentation.
36. How does TPC perform window printing?
(1) Use the "Button" print window function;
(2) Use the function !SetWindow() to print;
(3) Use the print window function of the “Window Operation” component in the running strategy.
37. How to fill the TPC print window with paper?
(1) Create a new project, select 7062K as the TPC type, and confirm;
(2) Create a new window 0, set the window properties, and in the basic properties page, select white for the background color;
(3) Window Properties: Activate the extended property page, set the window view size to A4, check the landscape print window option, and confirm.

41. How to implement a pop-up child window?
This can be achieved using the OpenSubWnd() function. For details on how to use this function, please refer to the MCGS help documentation.
42. Save the values as the initial values for the next power-on after a power outage?
In the exit strategy script, use the !SaveSingleDataInit() and !FlushDataInitValueToDisk() functions to save the last value as the initial value for the next boot.
43. How to set the project operation period?
(1) The general version is set in the configuration environment under Tools—Engineering Safety Management—Engineering Operation Period Settings;
(2) Practice for extending the runtime of embedded projects:
A uses the StrComp() function to compare whether the time when it stopped running is the same as the current time, and assigns 1 to a variable (using a loop strategy);
When B is the same, i.e., the variable is equal to 1, use !SetDevice to stop the device from working, create a variable that triggers the pop-up password input window, and assign the variable 1 (using event strategy);
When the variable that triggers the password input window in C equals 1, the password input window pops up (you need to do this yourself), and the password input window is closed (using a startup strategy).
D uses StrComp to compare the entered password with the set password. If they are the same, it executes the !SetDevice function to start the device and clear the running time and the variables that triggered the password input window.
Communication problems
44. Why are there so few drivers in Device Manager?
(1) During the configuration software installation, is "Install All Drivers" selected? If not, the drivers need to be reinstalled.
(2) If no supported driver is found in the device window of the configuration software, check whether the device supports the standard Modbus protocol. If it does, you can use the standard Modbus driver under the general device in MCGS.
(3) Contact the regional distributor to customize the driver.
45. How many child devices can a general serial port parent device have?
The software itself is not limited; the main limitation is the system. For Windows, it is generally 255 serial ports; for TPC, it depends on the number of hardware interfaces.
46. Equipment debugging shows data, but the engineering screen shows no data?
(1) For newly created projects: A. Check if the maximum and minimum value ranges are set in the data object property settings; B. If there is no problem after checking A, it may be a driver issue, contact customer service.
(2) Originally, there was data displayed during equipment debugging and in the engineering screen, but after some changes were made, there was no data displayed. The customer was asked to add the driver again, use the counter to check, and then retest.
47. Can a PLC and a module be connected to the same serial port?
In principle, as long as the serial communication settings are the same, it should be fine. However, MCGS does not recommend this approach because there may be potential conflicts within the device protocol. For example, an instruction to write to a register of the PLC may be mistakenly interpreted as an operation on a module, leading to device access conflicts.
48. How do I check the communication status of a device?
In all MCGS non-board devices (excluding some customized devices), the first channel is the communication channel. That is, after entering the runtime environment and the device driver begins working, this channel returns the device's communication status; for example, 0 indicates normal communication, and a non-zero value indicates abnormal communication. Note: Do not enable device debugging to check the device status while the host computer is running, as this will cause communication problems.
49. What does a communication status of -8 mean?
Please check if the added channel address exceeds the limit. In this case, the problematic channel will display a value of -5.
50. The program prompts "serial port initialization failed" when running.
(1) Check if any other software on the TPC has opened the serial port, causing the serial port to be occupied. If so, close the other software occupying the serial port first.
(2) A non-existent serial port number is set in the parent device of the general serial port.
51. The TPC's COM2 port cannot communicate with the device.
(1) Check the hardware wiring;
(2) Check whether the parameters of the parent device of the general serial port are consistent with the device communication parameters;
(3) When downloading the project, is the serial port number of the parent device of the general serial port set to COM2? If not, it needs to be corrected.
52. Can data be read but not written?
(1) When adding a channel, is the channel's attribute set to "read-only"? If so, write commands cannot be executed on the channel.
(2) Check the PLC program to see if there are any other operations performed on this channel address in the PLC program;
(3) If the problem persists, please call customer service.
53. Does TPC support OPC communication?
No, it is not supported. The network version supports OPC communication.
54.200 PLC: Communication wiring between PLC and TPC7062K
(1) Connect the 7 positive and 8 negative pins of the TPCRS485 interface to the 3 positive and 8 negative pins of the PLC serial port.
55. 200PLC: Communication wiring between PLC and PC?
(1) Siemens PC/PPI cable with standard serial port model.
(2) Use an RS232/485 converter for connection. Connect the positive A and negative B pins of the RS485 to the positive 3 and negative 8 pins of the PLC serial port.
56.200PLC: TPC and PLC cannot communicate?
(1) To test whether the computer simulation can communicate with 200, first use programming software to test whether 200 can communicate. Check the parameter settings of the parent device and child device of the general serial port. Check whether the parameters are correct. Perform device debugging in the device window and check whether the communication status is 0.
(2) After successfully communicating with the computer, test whether it can communicate with the TPC and check whether the hardware connection is correct.
57.200PLC: Cannot communicate using a standard PPI cable?
If the PPI cable contains 8 DIP switches, the 5th DIP switch needs to be set to the freeport setting for normal communication.
58.200PLC: What are the reasons for the communication status change?
(1) Check if the communication delay setting is too short and set an appropriate delay time;
(2) If there is interference on site, shielded wires can be used and grounded.
(3) Refer to PLC "SMW22" to see if the PLC running program is too large.
59. 200 PLC: How to connect VW10 in the PLC?
Register type: V register; Register address: 10; Data type: 16-bit unsigned binary number.
Note: The VW data type is word, so 16-bit data must be selected.
Can 60, 200 PLC and TPC achieve multiple master and multiple slave functions?
(1) Siemens 200 PLC does not support multi-master architecture;
(2) MCGS can support one master station to connect to multiple 200 PLCs, ensuring that the communication parameter settings of all PLCs are consistent, and that the address of each PLC is distinguished.
Note: If a master station connects to multiple 200 PLCs, it may result in slow communication speed or unstable communication, so it is generally not recommended to use it this way.
61. Does the 200 PLC support freeport communication?
Siemens 200's freeport communication means that you can freely write your own communication protocol. If you need to communicate with MCGS, you need to contact us to customize the driver according to your protocol.
The existing communication method is as follows: if the communication method of the 200 free port is set to Modbus protocol, then the Modbus driver in MCGS can be used directly for communication.
62. Mitsubishi PLC: How to select a driver for programming port communication?
The Mitsubishi PLC programming port is 422 communication, using the Mitsubishi FX series programming port driver; the 232BD uses the Mitsubishi FX series programming port driver; and the 485BD uses the Mitsubishi FX series serial port driver.
63. Mitsubishi PLC: Programming port parameter settings?
The communication parameters should be set as follows: the serial port number should be the same as the serial port number to which the device is connected, the baud rate should be 9600, the data bits should be 7, the stop bits should be 1, and the parity should be even parity.
64. What communication protocols does Omron PLC support?
(1) HOSTL1NK protocol
Most Omron PLCs support the HOSTLINK protocol. They support IR, LR, HR, AR, TC, PV, and DM register types and support 4-bit addresses. They cannot read registers with addresses greater than 9999. When using them, the contents of the high address area of the register can be moved to the low address area for read and write operations.
(2) FINS Protocol
The FINS protocol is a newly developed serial port driver protocol by Omron, supporting CIO, WR, DM, HR, AR, TK, TS, CS, TIM, CNT, IR, and DR register types.
65. Omron PLC: Parent device parameter settings?
(1) The communication parameter settings of the general serial port parent device should correspond to the communication parameter settings of the PLC serial port. The default standard parameter settings of the PLC are: 9600,7,2,E (even parity).
(2) Users can set it as needed. It is recommended to set it to 38400,7,2,E for communication when the communication speed requirement is high.
66. Omron PLC: How to set the address?
The device address setting must correspond to the actual address setting in the PLC, and the register address must be consistent with the unit number in the PLC.
67.300 PLC: What are the communication methods between the PLC and the PC?
(1) Communicate via Siemens communication card (CP5611) according to the Profibus bus protocol;
(2) Communicate via the MPI cable that comes with the 300.
68.300 PLC: TCP communication, what driver needs to be added?
Communication can be achieved via Ethernet. You can add a general TCP/IP parent device or a CP443-1 Ethernet module device in the device window.
Note: Sub-device drivers for Siemens 300 and 400 are interchangeable.
69.300 PLC: Can it directly read AIAO data?
It cannot be read directly; you can switch to the DB block and then read the data.
How to connect a 70.300 PLC to a TPC7062K for communication?
(1) Original Siemens adapter;
(2) Shenzhen Liancheng MPI Cable, Model: UniMAT;
(3) Other brands of cables do not guarantee successful communication.
71.300 PLC: Adapter connection TPC terminal wiring sequence?
Wiring sequence: 2-3 swapped, 4-6 swapped, 7-8 swapped, 5 straight. However, the maximum communication distance cannot be guaranteed to be 50m.
72.300 PLC: Communication status is always -1?
This situation typically occurs when a channel that does not exist in the PLC is added to the channel connections. For example, connecting a channel to the I, Q, or M area may exceed the PLC's range, or connecting to a non-existent DB block in the V area may connect to an address that is not defined in the DB block.
How do I add devices when connecting a 73.300 PLC to a TPC?
When using the embedded version to connect to a Siemens 300 PLC, unlike the general version, you need to select the general serial port parent device to connect the Siemens 300/400MPI child device. Note that the communication baud rate in the parent device must be consistent with the PC adapter, and the parity must be selected as odd parity.
74. Modbus: Which communication methods does it support?
Standard Modbus RTU and Modbus ASCII are serial communication methods, while Modbus TCP is an Ethernet communication method.
75. Modbus: How do addresses correspond?
The register addresses in the MCGSModbus driver need to be set starting from 1, with an offset of 1 from the actual device address. That is, if you need to acquire address 0 in the actual device, you need to set the register address to 1 when adding a channel; if you need to acquire address 5 in the actual device, you need to set the register address to 6 when adding a channel, and so on.

94. How to achieve engineering migration between TPCs of the same model?
(1) Enter the TPCCE operating system and copy the three files Project (folder), mcgsCE.exe (executable file), and backup (folder) from "My Computer" to the USB drive.
Project (folder) and mcgsCE.exe (executable file) path: My Computer harddiskmcgsbin
backup (folder) path: My Computer HardDisk;
(2) Insert the USB flash drive into the same model TPC to be ported, and copy the 3 files from the USB flash drive to the corresponding path;
(3) Restart the touchscreen.
95. How to test the TPC serial port?
TPC serial communication methods: RS232, RS485
Taking RS232 serial communication as an example:
(1) Connect the PC serial port and the TPC serial port with a serial port swapping cable;
(2) Run Comm.exe on the PC and set the communication parameters;
(3) Enter the TPC CE operating system, double-click "My Computer", enter the HardDisk folder, double-click CommThread_V2.2.exe (if this file is not available, you can download "TPC_Serial Port Test Tool" from the company website → Download Center → Common Tools page and copy it into the corresponding directory of TPC), and set the communication parameters to be the same as those of the PC.
(4) In the Comm and CommThread windows, select "Open Serial Port" respectively, and perform a single data transmission and 2000 consecutive transmissions respectively to check whether the data received in the receiving area is correct and whether there is any data loss or garbled characters.
(5) After performing the above operations, if the sending and receiving of data are normal, it indicates that the TPC serial communication is normal.
Note: When performing serial port testing, ensure that neither the PC nor the TPC serial port is occupied.
