BCU 1 controlling all modules, BCU 2 in router mode
BCU 2 controlling all modules, BCU 1 in router mode
Notes:
• The local modules must be connected to successive channels starting from CH1.
The immediately following channels are connected to the other BCU and routed
to the local modules. There must be at least as many local modules as there are
routed channels.
• In PLC control, any switch-overs must be done in stopped state, and so that at
least one BCU is in router mode at any given time.
• Additional rules or restrictions may apply when using the router mode with other
control programs. See the appropriate firmware manual.
