Hi
Does anyone know a neat way to allow multiple (x6) identical looking HMIs (TP700) to talk to one PLC (315-2dp/pn). Although they all look identical, each one controls a different section of the machine.
I am trying to avoid having 6x HMIs in TIA portal all with slightly different tags, and then having to edit 6 times to make one change.
At the PLC end I was thinking to have a data type 'HMI' and declare an array of 6 of these.
Thanks
