Chapter 5 Configure Your Expansion I/O Module
Units Set as °C or °F Sets the temperature unit to be used by
the channel.
RTD Wiring Type Set as any of the following:
• 2-wire
• 3-wire
• 4-wire
The wiring type for channel x.
This parameter is only available when the
Sensor Type for the channel is RTD or (0
to 500 Ohm).
RTD 2Wire Cable
Resistance
Replace value from 0.0
ohms…500.00 ohms to
0.0 ohms…655.35 ohms.
The specified cable resistance for the
2-wire cable. When the RTD 2Wire Cable
Resistance value is smaller than the input
value, it is subtracted from the input
value during each read. When the value
is greater than the input value, the
under-range or open status bit is set (1).
To configure the wire resistance, the
Sensor Type must be RTD or (0…500
Ohm) and the RTD Wiring Type must be
2-wire.
Otherwise, this parameter is not
available.
