Formal parameters and actual parameters
Parameters can be set on the MBS standard function blocks. Formal
parameters are established in the block header. The user must assign a
corresponding actual parameter to each formal parameter. When the
standard function block is called up in the user program, the formal
parameters will be replaced by the user-specific actual parameters.
INFORMATION
Depending on the programming language selected on PSS WIN-PRO,
designations for formal parameters and operands may differ from those
found on PSS SW PG. Any designations that are different will
automatically be replaced by PSS WIN-PRO.
Further information is available in the programming manual for “PSS SW-
PG” or “PSS WIN-PRO”.
