Link object address to modbus register
#4
Hi,

2020 is not a register, it's the number you need for the command interface that is build into the iEM devices, with this interface you can do everything on the device over the modbus connection that usually is done on the display of the device. To use the command interface you must disable the COM protection on the device by using the display once (default enabled).

After that you can use this script to reset the counters:
Code:
123456789101112131415
require('luamodbus') mb = luamodbus.rtu() mb:open('/dev/RS485', 19200, 'E', 8, 1, 'H') mb:connect() mb:setslave(1) -- Enter the correct Modbus slave address of the kWh meter -- Reset partial counters mb:writeregisters(5249, 2020, '') -- Results of Reset partial counters r1, r2 = mb:readregisters(5374, 2) log ("Result Command: " .. r1log ("Result Code: " .. r2) -- 0 = valid operation, 3000 = invalid Operation, 3001 = Invalid Parameter, 3002 = Invalid number of parameters, 3007 = Operation not perfomed mb:close()

BR,

Erwin
