How to connect varible in PLC with variable in Magelis? (for example: input %I0.1 in PLC with some swith button in magelis) I want set ref. speed of AC motor on HMI( magelis xbt gt4330). PLZ help me!

 

you create in the Magelis a variable "discrete" format and address it for instance to %mw0.0
The format for the set point should be a register (%MWx)or double (%MWx+1 = %MD) or floating (%MWx+1 = %MF)

That's all!!
You can't write a physical input (%Ix.y) from any devices. If you need to read it you must copy &Ix.y in %M memory.
