40041: ANALOG INPUT #0 VALUE
40042: ANALOG INPUT #1 VALUE
40043: ANALOG INPUT #2 VALUE
40044: ANALOG INPUT #3 VALUE
These registers return the measurement of each channel, converted to engineering units. The values are stored in the registers as
16-bit signed integers. Values for the RTD and Res 500 Ohm sensor types are stored with one implied decimal place. Values are
stored as integer ohms for Res 2000 ohm sensors, and one decimal place is implied for Potentiometer inputs.
For example:
• Input type set as RTD:
• Input type set as Potentiometer: 400 stored in the register indicates 40% of the nominal maximum value of the potentiometer
• Input type set as Res 2000 Ohm: 1256 stored in the register indicates 1256 Ohms
• Input type set as Res 500 Ohm: 1352 stored in the register indicates 135.2 Ohms
NOTE: When INIT mode is active, the analog input measurements are not updated.
40050: BREAK STATUS
When a break condition is detected (e.g., broken sensor, disconnected cable, or over temperature) the bit corresponding to the
channel is set to 1.

Description
41241: OFFSET CHANNEL #0 VALUE
41242: OFFSET CHANNEL #1 VALUE
41243: OFFSET CHANNEL #2 VALUE
41244: OFFSET CHANNEL #3 VALUE
These registers contain the offset values for each input.
The values are expressed in ohms for the Res 2000 ohm input, tenths of ohm for Res 500 ohm input, tenths of % for the
potentiometer input and tenths of °C for the RTD input.
The register format is a 16 bit unsigned integer.
