I want to have a simulator mode for operator in my project which enabling it cause a script run and manipulate all tag and simulate a process behavior.
If I create all tag type to memory writing to tag is possible in script but in real project some tag value comes from PLC and I can’t find any way to disconnect tag from updating from PLC while the quality is remain good and able to write to it in script. For example I do this by driven scan class and set slow rate to 0 to disable scaning from OPC but this cause quality get bad and write on tag is impossible.
So I came to this idea that some how changing the tag type from memory and OPC and vice versa in script.
Or force to set quality to good for all time for OPC tag and force to write value to them. are these method possible in igniton?
If not what is the alternative solution for this? (make a simulate mode in project)
