B3: Several operator panels connected to several NCUs, distributed systems - only 840D sl
Note
If the bus node addresses on the MPI bus are configured in conformance with SIMATIC, the
configuring engineer can read out the assigned addresses using a SIMATIC programming
device and use them to create the NETNAMES.INI file.
VI. Channel data
The control unit switchover option can work only if the control unit knows how channels are
assigned to NCUs so that it can set up links between the control unit and NCUs. (Channel
menu).
Concept
The following steps are necessary:
1. Definition of technological channel groups
2. Assignment of channels to groups
3. Assignment of NCUs to channels
4. Definition of power-up link
NCUs are addressed indirectly on the control unit on the basis of channel group and
channel. See Section "Operator interface".
