Error Handling
When an error exists on any receiver, the function cannot definitively determine the result of
the comparison and an error will be generated. Use Error Handling to select the output's val-
ue and error status.
Options:
• True Good
: outputs value is true (on) with no error
• True Bad
: outputs value is true (on) and has an error
• False Good
: outputs value is false (off) with no error
• False Bad
: outputs value is false (off) and has an error
Equal To
The output (T/F) is on when receivers A and B are equal to each other. See Tolerance.
