Function principle

The configuration of a Flexi Link project requires two steps.
 The first step is the configuration of the network settings and the Flexi Link address.
Wiring errors or the presence of devices that are not suitable for Flexi Link projects
are detected in this step automatically by the system.
 The second step is the configuration of the individual stations in the system: CPU
module, safety I/O modules, connected elements, network modules, logic and the
process image for the Flexi Link network.
7.2.1 Flexi Link address
The Flexi Link address is required by the Setting and Monitoring Tool to uniquely
identify each of the up to 4 stations in a Flexi Link system. This is the first important
setting in order to configure a Flexi Link system.
The Flexi Link address ranges from A to D and is freely configurable. For detailed
information on how to assign Flexi Link addresses to connected stations please see
Section 7.4.3.
7.2.2 Flexi Link ID
The Flexi Link ID is necessary for the stations in a Flexi Link network to communicate
with each other. All stations in a Flexi Link system must have an identical Flexi Link ID
in order to exchange their process image information. This ensures that only stations
that belong to the same Flexi Link system can communicate with each other. If a
differing Flexi Link ID is detected in a Flexi Link system, all connected stations will
change into "Invalid configuration" mode (MS LED flashing
The Flexi Link IDs are numeric values that are calculated from the default values for
the process image. This means that a change of the default values for the process
image of any station will change the Flexi Link ID of all stations. Adding or deleting a
station will also change the Flexi Link ID of the system.
Note If a change is made to any station's process image, you must transfer the new
configuration to all stations (e.g. Transfer all in the Flexi Link network settings view).
This will set all Flexi Link IDs simultaneously to the same value. Not doing so will lead
to a Flexi Link ID mismatch in the system and thus interrupt the safety communication
between the stations.
The Flexi Link IDs are a part of the configuration and are transferred and saved with
the configuration in the memory plug of each connected WS0-CPU1 or WS0-CPU3
module.
The Flexi Link IDs for the current configuration in the Setting and Monitoring Tool are
always displayed in the Flexi Link menu bar. The Flexi Link IDs that are currently
stored in the individual stations are displayed in the Flexi Link System overview and
compared to the Flexi Link ID of the project on the PC, while the station is connected.
If the Setting and Monitoring Tool detects a Flexi Link ID mismatch, a warning sign is
displayed. On the right side of the screen a recommendation is given how to proceed:
