Map the sensors and actuators tags as shown in the image below.įinally, click on CONNECT, close the Driver window and start the simulation (press F5).Wecon hmi software free download. Next, set Register Inputs and Register Outputs to 0, since we are not using any in this tutorial. Select Modbus TCP/IP Client from the Driver list and click on CONFIGURATION. Open any scene in Factory I/O and click on File > Driver Configuration.

When prompted to download the program to the PLC, click on Yes. If a device which is not a Delta PLC is connected, users can use the hexadecimal four-digit MODBUS address of the device for data exchange. A Delta Ethernet master can read/write data from/into a slave. The Data Exchange is used for configuring exchange of data between PLC via network. Next, click on Online > Login ( Alt + F8). Click the data exchange tab, the interface below will appear. Now, map the global variables (2) defined in step 5 as shown in the image below. Next, click on Add Device.ĭouble-click on Modbus TCP Slave Device (added in the previous step) and open Modbus TCP Slave Device I/O Mapping (1). Right-click on Ethernet and select Add Device., expand Fieldbusses > Modbus > Modbus TCP Slave Device and select Modbus TCP Slave Device. Next, expand Fieldbusses > Ethernet Adapter and click on Ethernet (2). Right-click on Device (CODESYS Control Win V3) (1) and select Add Device. Now, check the FIO symbols and click on Build. Now, Right-click on Application and select Add Object > Symbol Configuration. In the toolbar click on Build > Build ( F11). and select the network path to the controller. Get back to CODESYS and in the project tree, Double Left-click on Device (CODESYS Control Win V3) and then on Communication Settings. Right-click on CODESYS Control Win PLC icon (Systray) and select Start PLC.
