Use the and keys to navigate between the operand value, operator, and operation
priority. To change a value, use the and keys to scroll through value choices for each
value. Use the key to navigate from one screen to the previous screen when the cursor is
on the V1..V4 line, and the key to navigate to the next screen from the PR1..PR3 line. Use
the OK key to accept changes.

The analog math error detection block sets the output when the referenced analog math 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 checkbox, the output is reset prior to the next execution of the function
block. If not, the output retains its state until the analog math error detection block is reset with the R
parameter.
In any scan cycle, if the referenced analog math function block executes before the analog math error
detection function block, the error is detected in the same scan cycle. if the referenced analog math function
