Manual S5-115FSTEP 5 OperationsUnconditional block call ”JU”One block is called within another block, regardless of conditions.In the case of jump operations to missing blocks, the operating system of the CPU 942-7UF12responds differently depending on the operating mode.• If a jump is called to a missing block in safety mode, the S5-115F stops.• If a jump is called to a missing block in test mode, the jump is not executed and the programprocesses the next operation. The S5-115F remains in RUN.For this reason, construction of the complete user program step by step by successively loadingblocks is possible without continually rewriting OB 1. It is therefore possible to program OB 1with all planned block calls.Example: A special function has been programmed in FB 26. It is called at several locations in theprogram, e.g. in PB 63, and processed......JU FB 26.The ”JU FB 26” statement in programblock PB 63 calls function block FB 26.STL ExplanationProgram SequenceaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaPB 63 FB 26JU FB 26EWA 4NEB 811 6149-023-33
