10.8 Call SFB Format Description CALL SFB n1, DB n2 Program Control Instructions This instruction is intended to call the standard function blocks (SFBs) supplied by Siemens. The CALL instruction calls the SFB that you entered as address, independent of the RLO or other conditions. If you call a system function block with CALL, you must provide it with an instance data block. After processing the called block, processing continues with the program for the calling block. The address for the logic block can be specified absolutely or symbolically. Passing parameters (incremental edit mode) Status word The calling block can exchange parameters with the called block via the variable list. The variable list is extended automatically in your Statement List program when you enter a valid CALL instruction. If you call a system function block and the variable declaration table of the called block has IN, OUT, and IN_OUT declarations, these variables are added in the program for the calling block as a list of formal parameters. When calling the system function block, you only need to specify the actual parameters that must be changed from the previous call because the actual parameters are saved in the instance data block after the system function block is processed. If the actual parameter is a data block, the complete, absolute address must be specified, for example DB1, DBW2. The IN parameters can be specified as constants or as absolute or symbolic addresses. The OUT and IN_OUT parameters must be specified as absolute or symbolic addresses. You must ensure that all addresses and constants are compatible with the data types to be transferred. CALL saves the return address (selector and relative address), the selectors of the two open data blocks, and the MA bit in the B (block) stack. In addition, CALL deactivates the MCR dependency, and then creates the local data area of the block to be called.
