Restrictions for switchover of operator components

Rejection of link
On switchover to another NCU, the NCU selected for the new link may reject the connection.
There may be a defect in the NCU or no further operator panel can be accepted. In this
case, the HMI Embedded automatically switches over to connection 1 after approx. five
seconds. HMI Advanced displays "#" for the variables.
Alarms, messages
The operating characteristics depend on the HMI type:
1. HMI Embedded/OP 030
2. HMI Advanced
Operator interface
The operating characteristics depend on the HMI type:
1. HMI Embedded
2. HMI Advanced
3. OP030
When the HMI Embedded and HMI Advanced are used in the standard configuration
(Section "Configurability"), it is not necessary to configure the operator interface. If variables
of different NCUs need to be output simultaneously in a display, configuration is necessary.

Due to the equipment restrictions on driver level and the limited working memory, only the
alarms/messages of one NCU can be processed at any one time.
Only one alarm text file is managed. The NCU name assigned in the NETNAMES.INI file
is displayed as the NCU identifier in front of every alarm or message. To obtain user texts
specific to the NCU, it is possible to define user areas in the PLC for certain NCUs. The
alarms/messages of all connected components can be processed and displayed
simultaneously.
Only fields and variables of one NCU can be displayed simultaneously in a window. Only
the alarms and messages from the NCU which is currently connected to the PCU are
displayed.
Up to four connections (one active connection, three other connections) can be displayed
simultaneously via user configuration (OEM). All the variables (alarms and messages) of
a connection must be contained in one window (window-specific connections).
Fields and variables of different NCUs can be displayed in the same window (as an OEM
application). Alarms and messages from all the NCUs connected to the PCU can be
displayed.
OP030 can only be configured as a "1 : 1" connection to an NCU.
