Note 1 : menu parameters can be used as “Holding Register” or “Coil.0tyP
Note 2 : Received "ModBus input register value" is multiplying by 1000 (based on ) and mV value reached.
For example ;
if modbus value is 2842, (for = 2 ( )) 28.42x1000 = 28420 mV, ie 28.42V
if modbus value is 2842, (for = 3 ( )) 2.842x1000 = 2842 mV, ie 2.842V
