Triggering a screen page change in the PLC
The #Sys2Plc object makes it possible to trigger a screen page change by pairing the EPAM system variable /S/SYS/NewPage with a PLC variable, e.g. PLC/NewPagename. If, for example, the variable PLC/NewPagename in the PLC project is set with the value ‘#Page=<name>’, the value ‘#Page=<name>’ is transferred to the EPAM system variable and a screen page change is executed to page <name>.
