EX Series CC-Link Bus Adapter
The EX-1040 is a CC-Link bus adapter module, and each module can be expanded to support up to 32 input/output modules.
CC-Link is a fieldbus protocol used in industrial automation to enable data communication and control between devices. The CC-Link protocol is primarily used for real-time control and monitoring in industrial automation systems, including sensor data acquisition, control command issuance, and machine status monitoring.
The CC-Link protocol features high speed, high reliability, and high flexibility, and is widely used in industrial robots, CNC machine tools, automated production lines, and other fields.
Today we will introduce the connection and configuration of the DEKW EX-1040 module with GX-Works.
01. Communication Connection Diagram
Note: Add terminating resistors (110Ω) to both ends of the network. The connection method of the terminating resistors is shown in the figure below.

03. New Project and Communication Parameter Configuration
Open the GX-Works2 software, select the actual CPU model in the field, and then go to "Parameters" > "Network Parameters" > "CC-Link" in the left navigation bar of the project. Configure the CC-Link slave settings and CC-Link network parameters in the CC-Link parameter settings window.
Configure slave station information. In the CC-Link parameter settings interface, select "Site Information" to configure parameters such as station type.
For specific configuration details of the slave station parameters, please refer to the following rules for setting up the EX-1040 as a remote device station:
The CC-Link adapter EX-1040 is configured as a remote device station in the Mitsubishi GX-works software. Each station has 32 points. This can be set according to the specific IO points connected to the EX-1040 by the user. A maximum of 4 logical stations can be set, with each logical station containing 32 points. A maximum of 4×(32DI+32D0+4AI+4A0) can be connected.
The CC-Link remote I/O adapter supports two logic station settings, determined by the first and last five bits of the baud rate DIP switch. The first five bits correspond to five communication levels and represent a fixed four logic stations, a number that cannot be changed by default. When the switch is set to the last five bits, the number of logic stations can be changed according to actual needs, while the communication rate still corresponds to the rate of the first five bits. Logic stations can be flexibly configured as required. A group of 16 digital inputs/outputs constitutes one logic station, and a group of 4 analog inputs/outputs constitutes one logic station.
For example: when five EX-1040 units are connected to the PLC, and one EX-1040 unit is connected to EX-200H, EX-300H, EX-4414, and EX-5414, and the other two units are configured similarly, the communication speed needs to be adjusted according to the master station.
After setting the DIP switches, based on EX-200H, EX-300H, EX-4414, and EX-5414, we know that the IO module has one set of 32-point input/output, one set of 4-channel analog input, and one set of 4-channel analog output. The number of logic stations is taken as the maximum value, which is 1 set of logic stations. Therefore, the DIP switch position number of each EX-1040 needs to be separated by two bits. Specifically, the first group station number is 1, the second group is 2, the third group is 3, and so on.
