2.2.5 Channel menu for control unit management for an m:n configuration (powerline)
m:n configuration
m:n configuration means a group comprising m HMI Advanced units and n NCU units. The
HMI units for operating the relevant NCUs can be freely switched over during operation. For
each of the switchover targets of an HMI, one channel menu is configured in the
NETNAMES.INI file for each individual HMI. The individual switchover targets are declared
as a pair comprising an NCU and the processing channel on that NCU. Because the
machine control panel (MCP) for an HMI also has to be activated when that HMI is switched
to another NCU, the machine control panel must be assigned to the HMI in the configuration.
The configured channel menu is called up on the HMI by pressing the channel switchover
key. The switchover target can be selected and switchover triggered via the softkeys.
NOTICE
One NCU may only have two active connections (HMIs) at any one time. This must be
taken into account for all HMIs in the configuration in NETNAMES.INI for the entries
DEFAULT_logChanSet and DEFAULT_logChan with which the connection to be
established is defined after booting.
The following switchover options are described by the configuration specified in the example
of the NETNAMES.INI in the appendix:
