Solution
In the OB100 (the call for FB1), set MCP1BusAdr to 255 and MCP1Stop to true.
In the OB1, scan the "MMCBTSSready" (DB10.DBX108.3) signal. If this is set, write the
MCP address from DB19.DBB123 (MCP index) to the DB7.DBB27 before removing the MCP
stop bit DB7.DBX62.1. MCP is now active.
If the "MMCBTSSready" (DB10.DBX108.3) signal is now removed again (the HMI switches
to another NCU), the MCP stop bit DB7.DBX62.1 will have to be reset.
