Temperature Controller ATR14 display value is Modbus value
Posted: 16/10/2017, 16:34
The ATR141 and ATR142 Temperature controllers Display values are not same as Modbus Register Values (both Register 1000 and 1100). Sometimes, the Modbus value corresponds to Display value (about 2% of the time), Display value is more than Modbus value by 0.1F (85% of the time) while Display value is less than Modbus value by 0.1F (13% of the time). Not sure what is going on. Any help? My Modbus master is Labview and I have a Modbus Gateway from TCP to serial RS-485 (2-wire). My Temperature Sensr is an RTD (PT100)
