9.6.4 Process IPSO Definition
The IPSO process definition provides signal range, measured min/max values, IPSO object type information.
Offset Name Value Description
0x08a8 Sensor Type
3317 Current (mA)
3316 Voltage (mv)
0x08aa Precision
0-24mA 1 – display as xx.x
0-1000 mV -1 – display as xxx0.0
0-2000 mV -1 – display as xxx0.0
0x08ac Sensor Trigger ?? Write any value to force a reset of min/max
0x08b0 Min Measured ?? Minimum reading since the last reset
0x08b4 Max Measured ?? Maximum reading since the last reset
0x08b8 Min Range
Range Minimum Maximum
0-24 mA 0 24 mA
0 – 1 Vdc 0 1000 mV
0 – 2 Vdc 0 2000 mV
0x08bc Max Range
9.6.4.1 Process Precision
The measured mA value is rounded to p/- 0.1 mA resolution.
The measured mV value is rounded to p/- 10 mV resolution.
9.6.4.2 Process Sensor Trigger Function
The Sensor Trigger function is used to reset the IPSO min/max values as well as control the Calibration process.

Setting the Reset Min/Max bit to 1 will reset the Min/Max values recorded by the IPSO process. No User
Calibration process is supported on the Process inputs and all configuration bits should be written as 0.
