TimingMode DINT Selects timing execution mode.
0 = Periodic mode
1 = Oversample mode
2 = Real time sampling mode
For more information about timing modes, see Function Block Attributes.
Valid = 0 to 2
Default = 0
OversampleDT REAL Execution time for oversample mode.
Valid = 0 to 4194.303 seconds
Default = 0
RTSTime DINT Module update period for real time sampling mode
Valid = 1 to 32,767ms
Default = 1
RTSTimeStamp DINT Module time stamp value for real time sampling mode.
Valid = 0 to 32,767ms
Default = 0
AtuneAcquire BOOL Acquire PIDE AtuneData request.
Default is false.
AtuneStart BOOL Start Autotune request.
Default is false.
AtuneUseGains BOOL Use Autotune gains request.
Default is false.
AtuneAbort BOOL Abort Autotune request.
Default is false.
AtuneUnacquire BOOL Unacquire PIDE AtuneData request.
Default is false.
Output Parameter Data Type Description
EnableOut BOOL Indicates if instruction is enabled. Cleared to false if CVEU overflows.
CVEU REAL Scaled control variable output. Scaled using CVEUMax and CVEUMin, where
CVEUMax corresponds to 100 percent and CVEUMin corresponds to 0 percent.
This output typically controls an analog output module or a secondary loop.
CVEU = (CV x CVEUSpan / 100) + CVEUMin
CVEU span calculation: CVEUSpan = (CVEUMax - CVEUMin)
CV REAL Control variable output. This value is expressed as 0 to 100 percent. CV is limited
by CVHLimit and CVLLimit when in auto or cascade/ratio mode or manual mode
if CVManLimiting is true. Otherwise this value is limited by 0 and 100 percent.
CVInitializing BOOL Initialization mode indicator. CVInitializing is set to true when CVInitReq is true,
during instruction first scan, and on a true to false transition of CVHealth (bad to
good). CVInitializing is cleared to false after the instruction has been initialized
and CVInitReq is false.
CVHAlarm BOOL CV high alarm indicator. Set to true when the calculated value of
CV > 100 or CVHLimit.
CVLAlarm BOOL CV low alarm indicator. Set to true when the calculated value of
CV < 0 or CVLLimit.
CVROCAlarm BOOL CV rate of change alarm indicator. Set to true when the calculated rate of
change for CV exceeds CVROCLimit.
