[Question 1] How can Siemens S7-1200 PLC communicate and network with Acromag XT1123?
【answer】
The XT1123 is a ProfiNet input/output device from Acromag, featuring 16 digital I/O points. Figure 1 shows the appearance of the XT1123.
Figure 1
Figure 2 shows the ProfiNet network of S7-1200 and three XT1123s. They are connected by a switch and can be used for the transformation of smart factories, connecting the original non-Siemens systems to each other.

Communication connection between XT1123 and S7-1200 PLC
(1) Install the GSDML device description file
GSDML is an XML-based device description created when assembling a PROFInet device as a single component. It includes the following data : (a) the name and ID number of the PROFInet device; (b) the IP address of the PROFInet device , the access method for diagnostic data, and the device connection method; (c) the hardware allocation of the PROFInet device , the device interfaces, and the variables, data types, and formats defined for each interface; and (d) the storage location of the PROFInet device within the entire project. Figure 3 shows the import of the XT1123 GSDML file into the S7-1200, and Figure 4 shows the XT1123 directory after installation.

(2) S7-1200 establishes ProfiNet connection with XT1123
Figure 5 shows the network structure after the S7-1200 and XT1123 establish ProfiNet. After the network structure is added, the XT1123 input/output devices can be configured, such as modifying the I/O addresses.

[Question 2] How to configure the QJ71E71 Ethernet module of Mitsubishi QPLC?
【answer】
First, create a project. In Figure 6, set the network parameters, select MESECNET Ethernet, and then set the Ethernet parameters (as shown in Figure 7).
Figure 6
Figure 7
In the "Operation Settings" section, set the PLC's IP address to 192.168.0.8 , as shown in Figure 8. Click "Finish" to complete the settings. Additionally, you need to configure the QJ71E71 Ethernet module in the "Transmission Settings".

[Question 3] How to configure the SCADA software VijeoCitect when connected to a Quantum series PLC?
【answer】
(1) Create a new project in CiteExplorer
Double-click “MyProject” -> “NewProject”, as shown in Figure 9. In the pop-up dialog box, define the project name and description (Figure 10).
Figure 9
Figure 10
(2) Create a cluster in citectprojecteditor
As shown in Figure 11, create a cluster in CiteCutProjectEditor; define the cluster name and content , and then click Add (Figure 12); next, define the network address , which is the PC's IP address; create alarm/report/trend servers, etc.
Figure 11
Figure 12
(3) Configure driver
Create a driver in citectprojecteditor (Figure 13), enter the quick communication wizard, create IOServer, create IODevice, communicate with external IO devices, and select the driver "Modbus/TCP(Ethernet)-FastLinx" to link Unity's variable table to citect for use (Figure 14).
Figure 13
Figure 14
Finally, set the PLC's IP address and port number, configure the Unity variable table, and set the IOServer, etc.
After completing the above steps, you can create variables and screens.
