Station ID and Sensor Offsets
Each field station has a unique Station I D number. This number is s hown on the
configurat ion r epor t provided with the s y s tem, and on a label placed at the top of the
controller boar d. The databases identif y the sensor data f or eac h of t he input
channels using t his station ID along with a sens or offset number. The offs et is
added to the station ID to calculate the unique sensor number. These sensor
numbers are used to identify each of the input channels for any particular station.
The off s ets ar e as follows:
Offset Channel Type
+0 Digital Control Output Register
+1 Analog Input Channel #1
+2 Analog Input Channel #2
+3 Analog Input Channel #3
+4 Analog Input Channel #4
+5 Analog Input Channel #5
+6 Analog Input Channel #6
+7 Analog Input Channel #7
+8 Analog Input Channel #8
+9 Batter y V oltage Monitor
+10 Digital Status Input Register
+11 Digital Accum ulator Input Channel #1
+12 Digital Accum ulator Input Channel #2
+13 Digital Accum ulator Input Channel #3
+14 Digital Accum ulator Input Channel #4
For Exam ple: For a SIT65 with a Station ID# of 14200, the Sensor ID# for analog
channel one is 14201, analog channel two is 14202, battery monitor is 14209, digital
input accumulator for channel one is 14211, etc.
