Hi,

I have 6ES7 137-6AA00-0BA0 CM PtP communication module on ET200SP remote station with CPU 11517-3PN/DP

I am using it for Modbus Rtu communication with Energy meter EM6400.

On energy meter , I can access only these parameter settings:

Data Transmission rate: 19200(we setas 19200)

Parity: we set as Even

we are not able to access Data bits and Stop bits settings on energy meter. But in manual we found it as Data bits:8 and Stop bits:1

at PLC end we did hardware settings as:

as shown in attachment

I am not able to read any values ike current, voltage or frequency from energy meter

Please let me know, where it is going wrong.

I have connected Data + from energy meter to Terminal 12 on CP module and Data - to terminal 14 on cp module.

Thank you,

Damayanti
