8.14 Probe Register Map Layout
Each probe and sensor will follow a common layout pattern which provides consistency and
improves code reuse between platforms. All Instrument registers are Holding Registers. The
common probe register map layout is as follows:
Probe Common
Registers
9000 - 9209
Sensor Common
Registers
1 - 38
Parameter 1
Registers
38 - 45
Parameter 2
Registers
46 - 53
Parameter N
