Goals and Symptoms
Is it possible to connect the PC with Powersuite to the RS485 on the VW3A58303 and NOT to the RS485 on the control board?
The customer needs the displays and the connection to Powersuite at the same time.
I made some tests and it is impossible to get a connection with the option board. In Powersuite I used connection to ATV with bus-system and the correct ModBus address.
Parameters from the Menu 8: MB RTU, 19200, 8n1.
With the internal RS485 it works well.
Causes and Fixes
It's not possible to use PowerSuite on the Modbus card because at the first step connection of PowerSuite, there is an identification request and this one is not recognized by the option card.
