Configuration
4.21 Creating telecontrol connections for the ST7 communication
Bad connections
In the example the connection path "Route_2" was originally created from the application
"ST7cc_1" (PC_1) via the MSC network to TIM_12. This continued via the dedicated line
network from TIM_12 to TIM_11.
A connection path from the application via an MSC network or via modules with ST7
capability is not permitted.
The connection of the PC station to the MSC network was deleted in the meantime, so that
the connection points "ST7cc_1" and "TIM_12" are invalid and their symbols are red.
Redundant telecontrol connections
When different networks between two subscribers have been created in the network
configuration the different connection paths are shown in the "Add connection paths" table.
If you only want to use one connection, select only this connection in the table and click
"Add".
If you only want to establish a redundant connection, select two connection paths in the table
and click "Add". You specify the main and substitute paths between the subscribers after
closing the dialog using the "Configured connections" table.
Main and substitute path of a redundant connection
When you have created two connection paths for a telecontrol connection, the first of the two
is the main path and the second the substitute path. This is displayed in the "Priority" column
of the "Configured connections" table.
You can change the priority of the two connection paths later, i.e. the specification of the
main and substitute path. The arrow keys serve this purpose:
Delete invalid or redundant connections
If you have non-permitted or unwanted redundant connections you need to delete one
connection. Follow the steps outlined below:
1. To delete a connection in the table "Configured connections", select the connection you
do not need.
2. Delete the connection using the shortcut menu "Delete".
Rules for connection configuration
Note the following rules for connection configuration:
● A connection via an inconsistent network is invalid. Examples:
– Subscriber with incompatible modems
– Incompatible settings of two modems in a connection
– Incompatible settings between modem and network parameters
– Connections via nodes that are not configured as node stations.
● Two connections to one partner (endpoint) via the same interface of a module (start point)
are not permitted.
