3.15 The function block CONNECTION SHUTDOWN
3.15.1 Functional description
FB CONNECTION SHUTDOWN is used to deactivate a TwinSAFE connection. If the function block input
becomes active, the connection is closed, a shutdown command is sent to the FSoE partner, and
feedback is sent to the output. The connection is closed and the output is set if the communication
partner receives a shutdown command. The output is only reset when the connection to the FSoE partner
is in DATA state again.
Once the input of the function block is no longer active, the FSoE master tries to re-establish the
connection or the FSoE slave responds to the connection again.
This function block is required for modular safety concepts, in which machine components can be
exchanged without stopping the whole safety circuit, e.g. for a tool change. If a modular machine concept
is used, which includes machine options such as an optional feeder, these options should be realized in
dedicated additional TwinSAFE groups.
CAUTION
Deactive inputs
Please note that the signal used to shut down the connection must have the same safety level as the
signals of the shut-down connection.
