9.15 Replacing functions by subprograms
Output of auxiliary functions to PLC
When replacing auxiliary functions, calling the replacement subprogram does not initiate that the auxiliary
function is output to the PLC. The auxiliary function is only output if the auxiliary function is reprogrammed in the
replacement subprogram.
Block-search response
The replacement subprogram is also called in the search modes "Block search with calculation" and "Block
search with calculation in the program test mode" (SERUPRO). Any special features must be realized in the
replacement subprogram using the system variable: $P_SEARCH, $AC_SERUPRO.
Regarding collecting actions for "search with calculation", replacement subprograms behave just like "normal"
subprograms.
