Mathematic instruction error detection
Short description
The mathematic instruction error detection block sets an output if an error has occurred in
the referenced mathematic instruction function block.
Connection
Description
Input En
Enable the mathematic instruction error detection function block.
Input R
Reset the output.
Parameter
Referenced FB: block number of a mathematic instruction
Error to detect: Zero division, Overflow, or Zero division OR Overflow.
Auto Reset: Reset the output when the failure condition clears.
Output Q
Q is set high if the error to detect occurred in the last execution of the referenced
mathematic instruction function block.
0BA1- 0BA5:
The mathematic instruction error detection function block did not exist prior to
0BA6.
Parameter Referenced FB
The value for the Referenced FB parameter references the block number of an already-
programmed mathematic instruction function block.
Description of the function
The mathematic instruction error detection block sets the output when the referenced
Mathematic instruction function block has an error. You can program the function to set the
output on a zero division error, an overflow error, or when either type of error occurs.
If you select the "Automatically reset" check box, the output is reset prior to the next
If you select the "Automatically reset" check box, the output is reset prior to the next
execution of the function block. If not, the output retains its state until the mathematic
instruction error detection block is reset with the R parameter.
In any scan cycle, if the referenced mathematic instruction function block executes before
In any scan cycle, if the referenced mathematic instruction function block executes before
the mathematic instruction error detection function block, the error is detected in the same
scan cycle. if the referenced mathematic instruction function block executes after the
mathematic instruction error detection function block, the error is detected in the next scan
cycle.
