AC800M communication with Conzerve meters on Modbus
I want to communicate PM864 and Conzerve energy meter (em6433) via modbus on COM3-Serial Communication Port on CPU via rs485-rs232 converter; I have configured the COM3 with Modbus with ModbusHWlib 2-10-8 and set baud rate 9600 and parity even databytes8 and stop bits 1
using the MB connect block the meter state is 1 (meter is communicating and active).
but when using MBread block i get error -4902 (referring to help: cErrIllegalDataAddress: exception response from partner)
can any one give the details of Address and its format for the MBRead block( used address format at start address input :%MD10#3929)?

hi,
Can you please give some details about which MFM you are reading like Conzerv EM6400 or EM6436 like this?? if you add this details it will be more easy to provide the modbus address registers.
