Siemens 9510 Power Meter Modbus Gateway Issue

[DCIM_Support]

We have a few circuit breakers that are daisy-chain connected to Siemens 9510 power meter's COM1. We try to monitor the power meter and the circuit breaker via MODBUS.

Before enabling Modbus gateway on the 9510 meter, I was able to retrieve all power meter sensors from DCE with slave id 1.

After enabling Modbus gateway (COM1 protocol set as EtherGate or Modbus Master). I was not able to retrieve any power meter sensors. DCE only showed the Link Status. The link was also not stable. It went up and down.

I called ION support. They think it might be DCE issue. They used MODBUS tester tool and confirmed the tool can retrieve PM data with slave id 255.

Can you please help?

I have a similar problem, an d i put slave id 255 and go fine

DCE only allows slave id ranging from 1 to 247 though.

Upgrade DCE 7.3.1

We are using 7.2.7. I will upgrade our DCE to 7.3.1. By the way, how do you determine the slave ids of the circuit breakers that are connected to the power meter?

In my case, it see like a gateway all the elements

Do you configure power meter COM1 as EtherGate or Modbus Master? When I configure it as EtherGate, I could communicate with power meter using 255. I could not communicate with slaves with slave addresses. When I configured it as MODBUS Master, I could communicate with power meter using 255 and slaves with their addresses.

In my case i use as ethergate but it's on PM off Schneider, but can you use as master if you need to communicate PM and slaves
