t:m:n configuration
By t:m:n configuration we mean a grouping of t operating stations (TCUs with MCP), m HMI
systems and n NCK systems, in which the operating stations can be freely switched to the
various HMI systems in order to operate. In a two-stage process the switchover targets of
each operating station are individually configured in a channel menu.
The HMI systems remain permanently linked to the NCK they are assigned to. It is irrelevant
whether the HMI is an embedded HMI that runs on the NCU or a so-called HMI that runs on
a PCU. However, only one HMI may be linked to each NCK (statically), i.e. if an external HMI
Advanced is to operate the NCK of an NCU, HMI sl must be deactivated there (see: Service
command sc disable HMI).
During operation, switchover is initiated via the configured channel menu from the HMI.
From the point of view of the HMI, t:m:n operation is active if a channel menu is configured in
the NETNAMES.INI file.
Available switchover targets are defined via the address of the HMI and optionally to an NC
channel that must be assumed on switchover from the HMI. These switchover targets can be
combined in so-called channel groups. Channel groups are displayed on horizontal softkeys
in the channel menu, the switchover targets themselves (HMI, NC channel) are displayed on
the vertical softkeys assigned to a channel group.
