Square D PME 800

[iiotms]

I have a network security appliance for my OT environment and I'm getting a Modbus policy violation for address range, function code 232. Can anyone tell me what that might be? I see a source device communicating with the PME 800 and trying to determine if this is a false positive. My environment is rather large, and we are in the middle of doing extensive inventory to find out devices that are no longer in the environment and threats that may exist. 

Thank you!

Hello @iiotms ,

Are you saying you have Power Monitoring Expert (PME) talking to a PM800 device? Do you have an example of what the modbus request looks like?
