CSPID – PID MODULE PROGRAMMING
CRIMSON USER MANUAL - MODULAR CONTROLLER
AVAILABLE DATA
The following are the data values available to the Master, and therefore, may be mapped to
PLC registers. Decimal places are used to denote resolution only, and are not read or written
ie. a Power value of 10000 is interpreted as 100.00%.
Note: The following table shows available data for the CSPID1 module. In most cases, the
CSPID2 module contains the same data for both Loop 1 and Loop 2. e.g. Instead of listing
only Module1.PV, the CSPID2 will list Module1.Loop1.PV and Module1.Loop2.PV.
