DearPegaia: We are developing a system in which several PCs (5) withLabview
have to read / write variables on one S7 PLC (S7 1500)
via MODBUS TCP.
(I think the classic master - slave concept is diluted
in this application).

My questions are:

On the PLC side, do we have to use aMB_Serverfunction
with its respectiveMB_Server_DB
for each one of theLabviewPCs?

In that case, the Holding Registersaddresedby clients
must be indifferentsDB
or they can be in a unique global DB?

Thank in advance.​
