Program Control Instructions 10.10 Call Multiple Instance Format Description Status word CALL # variable name A multiple instance is created by declaring a static variable with the data type of a function block. Only multiple instances that have already been declared are included in the program element catalog. BR CC 1 CC 0 OV OS OR STA RLO /FC writes: - - - - 0 0 x x x 10.11 Call Block from a Library The libraries available in the SIMATIC Manager can be used here to select a block that • Is integrated in your CPU operating system ("Standard Library") • You saved in a library in order to use it again.

10.12 CC Conditional Call Format Description Status word Example CC Program Control Instructions CC (conditional block call) calls a logic block if RLO=1. CC is used to call logic blocks of the FC or FB type without parameters. CC is used in the same way as the CALL instruction except that you cannot transfer parameters with the calling program. The instruction saves the return address (selector and relative address), the selectors of the two current data blocks, as well as the MA bit into the B (block) stack, deactivates the MCR dependency, creates the local data area of the block to be called, and begins executing the called code. The address for the logic block can be specified absolutely or symbolically. BR CC 1 CC 0 OV OS OR STA RLO /FC writes: - - - - 0 0 1 1 0 STL Explanation A I 2.0 //Check signal state at input I 2.0. CC FC6 //Call function FC6 if I 2.0 is "1". A M 3.0 //Executed upon return from called function (I 2.0 = 1) or directly after A I 2.0 statement if I 2.0 = 0. Note If the CALL instruction calls a function block (FB) or a system function block (SFB), an instance data block (DB no.) must be specified in the statement. For a call with the CC instruction, you cannot assign a data block to the address in the statement. Depending on the network you are working with, the Program Editor either generates the UC instruction or the CC instruction during conversion from the Ladder Logic programming language to the Statement List programming language. You should attempt to use the CALL instruction instead to avoid errors occurring in your programs. Statement List (STL) for S7-300 and S7-400 Programming A5E00706960-01 10-15
