3.5.1 Interface signals of the HPU
The MCP simulation is available for the HPU. The MCP simulation of the HPU
must be parameterized as an MCP in function block FB1 so that the PLC basic
program can monitor the failure of the HPU.
The parameter setting for the start address n is set in the PLC user program
(FB1).

– Only keys displayed against a gray background are evaluated by the basic PLC program (FC26).
– Keys U1 to U4 and F1 to F5 or their inputs may be freely assigned by the PLC user.
FC 26 also exists and is analogous with PLC functions FC 19 and FC 25. It is
