FB9 call
CALL
Note
Input parameter "MCPEnable" must also be set to true to enable MCP switchover. The
default value of these parameters is set in this way and need not be specially assigned when
the function is called.
Alarm, error
The output parameters "Alarm1" to "Alarm6" and "Report" can be transferred to the DB2
areas for MMC alarm and error messages.
If execution of an MMC function has failed (for which an appropriate error message cannot
be displayed), status parameter ErrorMMC is set to 'logic 1' (e.g., booting error when no
connection is made).
