Sensor
Type/Id(M) 458 The type of sensor (RTD or
TC) selected for measuring
the Process Temperature.
The specific type of RTD or
TC selected for measuring
the Process Temperature R/W uint8 1 = TC
2 = RTD
RTD1 Type 459 The currently selected 2-
wire, 3-wire or 4-wire RTD
type. R/W uint8 0 = 2 wire
1 = 3 wire
2 = 3 wire
