Hello! I ask for help with the next task. The project has three stations implemented using RIO technology (modicon 580). The upper level is made using Scada Vijeo Citect 7.5, controllers are polled via the modbus tcp / ip protocol. The task is to transfer data from the% MW registers of one controller to the% MW register of another controller. I understand that this can be implemented through Scada Vijeo Citect 7.5. For this, in Scada I created Tag real №1 (plc №1) and Tag real №2 (plc №2). How then through Scada to transfer the data of the registers% MW of one controller to the register% MW of another controller. I would be grateful for the help.
It is a simple assignment Tag1 = Tag2.
The options of how you implement that are numerous.
If you have a single tag, then do it as an event.
If you have many, then write a Cicode function, then call that function as an event.
The event would be configured to call your function at the periodic frequency of your choosing.
I am sure you have your reasons, but I would point out that messaging direct PLC to PLC is simpler and more reliable, and uses no tag count. Direct would be the usual method.
