FC PathStatus
Function
The block (FC) shows the status of the path to a partner from the perspective of the local
TIM.
A maximum of 2 paths (main and substitute path) to a partner can be configured. Both paths
must begin or end on a local TIM.
The block shows the following:
● The paths via which the partner can be reached.
● The path currently being used
● The TIM interface via which the main path was configured.
● The TIM interface via which the substitute path was configured.
The path of a connection is specified as a combination of the used interfaces of the TIM and
the status of the path.
In the output byte PathStatus the following bits are reserved:
● Two bits for the interface of the main path
● Two bits for the interface of the substitute path
● Two bits for the status of the main path
● Two bits for the status of the substitute path
The FC can be called at any point in the cyclic user program (OB1) after calling the FC
BasicTask.
If the status of the path to more than one subscriber is to be shown, a corresponding number
of FC calls need to be programmed in the user program program.
