MONITOR VARIABLES: INPUTS → Pot Input
VARIABLE DISPLAY RANGE DESCRIPTION
Wiper Position
Wiper_Position
0x3318 0x00
0 – 100 %
0 – 1000
The calculated position percentage from the 2-wire or 3-wire
potentiometers.
This read-only variable is repeated in the Pot Input parameters.

Resistance
Pot_Resistance
0x3319 0x00
0 – 15000 Ohms
0 – 15000
The calculation of the wiper resistance to ground.
The 1351 System Controller’s dynamically calculated resistance of a
connected potentiometer. Pin 20 is the wiper (between pin 21, Pot Hi and
pin 8, I/O Gnd).
This read-only variable is repeated in the Pot Input parameters.

Resistance
RTD_X_R
Monitor variable CAN Index
RTD_X_R
1 = 0x3310 0x00
2 = 0x3311 0x00
3 = 0x3312 0x00
4 = 0x3313 0x00
0 – 20000 Ohms
0 – 20000
The measured RTD’s resistance at the input pin
Note: Replace X with 1 – 4 for the specic RTD Input (see example wiring
diagram).
This read-only variable is repeated in the RTD Input parameters.

RTD_X_OUT
Monitor variable CAN Index
RTD_X_Out
1 = 0x3314 0x00
2 = 0x3315 0x00
3 = 0x3316 0x00
4 = 0x3317 0x00
–32768 – 32767
–32768 – 32767
The “value” at the RTD input corresponding to the RTD resistance point. The
meaning of the output value depends on the type of sensor used and the
mapping.
Note: Replace X with 1 – 4 for the specic RTD Input (see example wiring
diagram).
This read-only variable is repeated in the Pot Input parameters.
