Device name

->PM8240

Communication Method

->Modbus TCP only

At the user site SI team question me, how to reset kwh value using only Modbus tcp protocol

Before I was check Modbus map it but kWh parameter can't reset.

Otherwise I can do it, PME handle easily but there user can’t it

Please give me good idea?

In general for ION meter the master reset is external pulse number 19(ep19) Modbus address is 42019 try it.

External Pulse Module #19 is the Master Reset in the default framework.  It's output can be toggled via Modbus at address 52019 (write a 1 to address 52019).  Modbus Map Access in the Security Options Module must be set to Yes to enable this functionality.
