Module Data, Status, and Channel Configuration

Linear Relationship Between Temperature and PID Counts
The amount over and under user range (full-scale range -410 to +16793) is
also included in the signed integer provided to the controller.
Allen-Bradley controllers, such as the MicroLogix 1500, use this range in
their PID equations. See Determining Effective Resolution and Range on
page 4-19.
Percent of Full Scale Data Format
With the percent of full scale data format, the module presents input data
to the user as a percent of the user-specified range. For example, for a
100
Ω
platinum 385 RTD, the range -200×C to 850×C is represented as 0
percent to 100 percent. See Determining Effective Resolution and Range
on page 4-19.
Selecting Input/Sensor Type (Bits 8 to 11)
You can set bits 8 through 11 in the channel configuration word to
indicate the type of input sensor, for example, 100
Ω
platinum 385 RTD.
Each channel can be configured for any input type. The valid input types
and bit settings are listed in the channel configuration table on page 4-6.
