3-14 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 3-20.
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 100Ω 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 3-20.
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, 100Ω 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 3-7.
