Topic: CL254
|
Each of the eight PID Loops has its own list of addresses associated with it.
C Memory Area - 40 Consecutive Bits
DS Memory Area - 15 Consecutive Integers
DF Memory Area - 25 Consecutive Floats
The table below list Bits, Integers and Floats along with their Nicknames and Descriptions used in the CLICK software Address Picker.
Since the user selects the beginning address for each PID Loop and each address type, addresses are listed by Type, Starting Address plus an Offset.
Example:
Cn+00 = Type C, n=starting address + 00
The Nicknames use abbreviations that make it easy to select the correct parameter for the proper function in the PLC Ladder code or your Operator Interface
