How to set contact in PLC with some switch in Magelis (for example I0.1)? Which type of variable use?

 

In the Vijeo Designer Software, configure the target communication parameter (e.g. PLC) for IEC addressing. You then have access to all addresses (%I0.1.0 is an Input). However, writing to an addressed input makes no sense. The actual input device (like a switch) would write over any value from the HMI. You can read an input but normally not write to it.
