PM5000 series and Modbus

[denise01 3]

Hello,

I would like to receive data from our PM5100 Power Meter via Modbus using a Omron PLC. I am sure that it will use Modbus RTU as I have controlled Altivar Inverters using this system. Does anyone know where I can access the Modbus Registry for this Meter? I really want to log KWH usage.

 

Regards

Many thanks cHud. Have you ever extracted value from the PM5100 before? I am sure I have to use Modbus RTU but maybe I will have to purchase a PM 5110?

Havent done it for a while. But we normally would use modbus tcp/ip to a gateway and the gateway would be modbus rtu to the different power meters.

How I did the Altivar Inverters was to use a Omron RS485 Communication Card to the Inverter. Download a Modbus RTU Protocol Macro to the card and then Read and Write values through ladder diagram programming using the registers. I know that we can buy Data Logging additions for the PM8000 but hopefully I will be able to retrieve data using my method.
