Read_Var

1 post in this topic

Hallo everybody,

 

I am using Modicon TM221CE24T in combination with HMI Weintek TM8071iE. I am trying to read and write some %MW from and on this HMI. Do I need to use, %Read_Var and %Write_Var function block to do this.I have already set numeric objects with corresponding adresses.  Connection between HMI and PLC is by Ethernet.
