Procedures Section 3-2
Note If a non-boolean data type is used for the input variable and only a numerical
value (e.g., 20) is input, the value for the CIO Area address (e.g, CIO 0020)
will be passed, and not the numerical value. To set a numerical value, always
insert an &, #, + or
− prefix before inputting the numerical value.
Example Programs:
If the input variable data type is boolean and a numerical value only (e.g.,
0 or 1) is input in the parameter, the value for CIO 000000 (0.00) or
CIO 000001 (0.01) will be passed. Always input P_Off for 0 (OFF) and
P_On for 1 (ON).
