Description
Control variable output for CV1. This value will
always be expressed as 0...100%. CV1 is limited
by CV1HLimit and CV1LLimit when in Auto mode or
in Manual mode if CVManLimiting is TRUE;
otherwise limited by 0 and 100%.
Control variable output for CV2. This value will
always be expressed as 0...100%. CV2 is limited
by CV2HLimit and CV2LLimit when in Auto mode or
in Manual mode if CVManLimiting is TRUE;
otherwise limited by 0 and 100%.
Control variable output for CV3. This value will
always be expressed as 0...100%. CV3 is limited
by CV3HLimit and CV3LLimit when in Auto mode or
in Manual mode if CVManLimiting is TRUE;
otherwise limited by 0 and 100%.
Initialization mode indicator for CV1. Set TRUE
when CV1InitReq, function blockFirstScan or
OLCFirstRun, are TRUE, or on a TRUE to FALSE
transition of CV1Fault (bad to good). CV1Initializing
is set FALSE after the function block has been
initialized and CV1InitReq is no longer TRUE.
Initialization mode indicator for CV2. Set TRUE
when CV2InitReq, function blockFirstScan or
OLCFirstRun, are TRUE, or on a TRUE to FALSE
transition of CV2Fault (bad to good). CV2Initializing
is set FALSE after the function block has been
initialized and CV2InitReq is no longer TRUE.
Initialization mode indicator for CV3. Set TRUE
when CV3InitReq, function blockFirstScan or
OLCFirstRun, are TRUE, or on a TRUE to FALSE
transition of CV3Fault (bad to good). CV3Initializing
is set FALSE after the function block has been
initialized and CV3InitReq is no longer TRUE.
CV1 high alarm indicator. TRUE when the
calculated value for CV1 > 100 or CV1HLimit.
CV2 high alarm indicator. TRUE when the
calculated value for CV2 > 100 or CV2HLimit.
CV3 high alarm indicator. TRUE when the
calculated value for CV3 > 100 or CV3HLimit.
CV1 low alarm indicator. TRUE when the calculated
value for CV1 < 0 or CV1LLimit.
CV2 low alarm indicator. TRUE when the calculated
value for CV2 < 0 or CV2LLimit.
CV3 low alarm indicator. TRUE when the calculated
value for CV3 < 0 or CV3LLimit.
CV1 rate of change alarm indicator. TRUE when the
calculated rate of change for CV1 exceeds
CV1ROCPosLimit.
CV2 rate of change alarm indicator. TRUE when the
calculated rate of change for CV2 exceeds
CV2ROCPosLimit.
