I'm trying to figure out how to write a script to change the PLC address a variable points to when a button is pressed. For example, integer variable "int1" is setup as external and points to integer address %MW10 in a twido PLC. When a button is pressed on the Magelis screen, I'd like to change the plc address so that "int1" will now point to %MW20. Not sure if this can be done. Any advice?
