Example of calling FB9
Note
Input parameter "MCPEnable" must be set to TRUE to enable the MCP switchover. The default
value of these parameters is set in this way and need not be specially assigned when the
function is called.
Interrupts, errors
The output parameters "Alarm1" to "Alarm6" and "Report" exist as information in the PLC and
are output in the event of M:N errors visualized on the HMI by the appearance of alarms 410900
- 410906.
If execution of an HMI function has failed (and an appropriate error message cannot be
displayed), status parameter "ErrorMMC" is set to 'logical 1' (e.g., booting error, when no
connection is made).

Value range Description
0 (FALSE), 1 (TRUE) Function is not supported. Operator
panel switchover Interlocking using
MMCx_SHIFT_LOCK in DB19
0 (FALSE), 1 (TRUE) Activate MCP switchover
1: MCP is switched over with operator
panel.

ator panel. This can be used to perma‐
nently link an MCP. See also
MMCx_MSTT_SHIFT_LOCK in DB19.

0 (FALSE), 1 (TRUE) Interrupt: No confirmation HMI 2 off‐
line!
0 (FALSE), 1 (TRUE) Interrupt: HMI 2 is not going offline!
