B3: Several operator panels connected to several NCUs, distributed systems - only 840D sl
2.2 Several operator panel fronts and NCUs with control unit management option
Explanatory notes on mmc_typ:
mmc_typ contains type and connection identifiers for the control units and is transferred to
the PLC in the event of a switching request. mmc_typ is evaluated as a priority for the
suppression strategy. See Section "Suppression".
Bit 7 = --
Bit 6 = TRUE:
Bit 5 = TRUE:
Bit 4 = TRUE:
Operator panel = PCU (incl. HMI Advanced/Embedded) with OP/TP
The user can specify four additional HMI types which the control unit switchover function of
the PLC also takes into account in its suppression strategy:
Bit 3 = TRUE:
Bit 2 = TRUE:
Bit 1 = TRUE:
Bit 0 = TRUE:
If no mmc_typ is entered in file NETNAMES.INI, then the HMI/HT6 powers up by the method
defined for standard functionality.
V. Description of NCU component(s)
A separate entry must be generated for every single NCU component connected to the bus.

*) For MPI bus: Since the associated NCU always occupies the next-higher address than the
PLC, the PLC address must not be 31. Address 31 can be assigned to a PCU, for example.

(reserved)
HMI is the server (HMI Advanced) and cannot be suppressed.
Operator panel/HT6 is the main control panel.
Operator panel/HT6 is the secondary control panel.
