Temperature Controller ATR14 display value is Modbus value
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)

Re: Temperature Controller ATR14 display value is Modbus val
Hi,
the value in the display is similar but not the same, because in the display there is a filter to avoid display display problem (process value not stable). In the ATR121/141/142 you can not disable this filter.
Best Regards.
