hi
i'm working a project that has a touch panel and a PLC.
configuration files of touch panel isn't available and i have just backup file of touch panel.
how to recognize shared addresses between PLC (S7-300) and HMI (TP270)?
best regard.
You can connect both (PLC and HMI) on MPI/DP network and then with PG/PC you will see, what addresses are on the network.
You know the address of PLC, so the other is HMI.
What do you mean by 'shared address'? I though that you mean MPI/DP address of HMI.
If you mean address of the tags(MW, DBW,...), that are shown on the HMI, then without good symbolic/comments in STEP7 program it'll be very difficult.
