Thank you Erwin, we'll try this ASAP.
Another question:
we have another system (a BT-Modbus interface by Emec for pool monitoring and control) that can read and wite coils but if we try to read or write holding registers 90% of the time give a "invalid data" result.
The line includes two PM-3250 by Schneider Electric and a Datamanager 2.0 interface by Fronius, this device is the third slave on the chain (W4K as master -> PM-3250 n°1 -> PM-3250 n°2 -> BT-Modbus -> Datamanager 2.0).
Any help will be appreciated, thanks
Update:
Often both PM-3250 return an error "response not from requested slave"
