Channel
Description
Remarks
Ch*_ClippingFunctionExe
cutionRequest
Ch* clipping function
execution request
ON: The clipping function is executed.
OFF: "Ch* clipping function upper limit" and "Ch*
clipping function lower limit" are turned OFF.
Validity condition: Level
Ch*_ClippingUpperLimitSt
atus
Ch* clipping function
upper limit status
Turns ON when the value exceeds the output clipping
upper limit while the clipping function is executed.
Ch*_ClippingLowerLimitSt
atus
Ch* clipping function lower
limit status
Turns ON when the value falls below the output
clipping lower limit while the clipping function is
executed.
● The upper limit and lower limit clip the output at the original output range resolution regardless
of whether scale conversion is executed or not.
■
Sample program
The following program executes the clipping function of the ch0. Specify a desired operation
when the upper limit is detected or when the lower limit is detected.
Declaration section
PROGRAM PRG_DAO1
VAR
bCh0_ClippingFunctionExecutionRequest: BOOL;
bCh0_ClippingUpperLimitStatus: BOOL;
bCh0_ClippingLowerLimitStatus: BOOL;
END_VAR
Implementation section
bCh0_ClippingFunctionExecutionRequest := TRUE; // Start detection
IF bCh0_ClippingUpperLimitStatus = TRUE THEN //Exceeded the upper limit
;
END_IF
IF bCh0_ClippingLowerLimitStatus = TRUE THEN //Below the lower limit
;
END_IF
