i'm currently working on mapping I/Os (From a PFC200 -> 750-1405 card) to the PLCs modbus.
In the 1405s settings I have created my variables, when I want to use them in the Modbus Slave Device mapping using Application.Var I get the error: "'var' is already defined in 'IoConfig_Globals_Mapping'. Can I not map them directly? It does work if I use a variable in between those but that doesn't seem elegant.
Thanks
