Using ION7550RTU as a remote display for PM820

[kaito_hokama_ry]

Does someone know how to configure ION7550-RTU as a remote display for PM820?

ION7550RTU: S7550B0N9B9A0A0A

Connection: RS-485

1. Modbus Import module or

2. Modbus Master Device module together with Modbus Master Map module

Then link output to Display module or do data logging or both.

Please see ION Reference

I setup Comm Module, Modbus Master Device Module and Modbus Master Map Module.

Then linked to Display Module but I still can't get date from PM820.

On Modbus Master Map Module, I put a data as "LbVln a,SR41120,FUINT16,NR1,S0.1,O0,".

Someone knows what the issue is?

In Desginer, hold down "Shift" and click Modbus Master Device module's output, do you see any values in the output regsiters? If not, check the "Modbus Master Option" module to assign the correct com port to "Serial Connection 1".

Thank you.
