Creating Telecontrol Connections For The St7 Communication - Siemens TIM 1531 IRC Operating Instructions Manual

Creating telecontrol connections for the ST7 communication

Single and redundant connections
For ST7 communication of a communication module, you need to create at least one
telecontrol connection in the "Network data" editor.
If two subscribers can be reached via different networks, to establish path redundancy for
modules with multiple ST7 capable interfaces you create a maximum of two connections
between the two subscribers. You specify redundant connections in the "Connection path"
table (see below).
Not all communication modules have serial interfaces or only one Ethernet port with ST7
capability. These modules cannot use redundant paths.
Opening the editor "Network data" > "Telecontrol" tab
To open the editor, follow the steps below:
1. Open the network view of the project.
On the right you will find the collapsed "Network data" editor.
2. Open the "Network data" editor using the arrow symbol.
The editor is displayed with several tabs, on the left the "Network overview" tab.
3. Expand the editor until the "Telecontrol" tab appears.
In this tab you configure the telecontrol connections.
Creating telecontrol connections for the ST7 communication of the module
For communication between two ST7 subscribers, you require a telecontrol connection. To
create the connection, follow the steps below:
1. In the "Starting point" box, click on a free row in the "Telecontrol" tab.
The drop-down list shows the configurable starting points that can use the ST7 protocol:
– S7 stations: Assigned CPU
– PC stations: Application (e.g. ST7cc / ST7sc)
For connections between an application on the master station PC and an S7 station,
always select the application as the starting point because it can only be selected in the
list of starting points.
