The Diagnostics tab of the multistation node in the I/O Manager provides information about the connections between the individual participants.

Diagnostics on multistation master:

Diagnostics on synchronized slave:

Current multistation mode

This shows which mode the participant is in. Possible options are "Master," "Synchronized slave” (Slave), "Non-synchronized slave" (Slave without Master) or "Standalone."

Table

In the table, the network connections between the slaves (control and data connections) are displayed.

The example in both images above shows a system, consisting of 3 stations. The master has a control and data connection each to both synchronized slaves. The synchronized slave has a control connection to the master as well as a data connection to the master and to the other synchronized slave.

Connections with non-synchronized slaves are listed in a separate group called Unsynchronized connections, if configured. The background color of the lines with non-synchronized connections has the following meaning:

• Green: Trigger events are actively exchanged via this connection.

• Orange: No trigger events are exchanged via this connection because, for example, there is already a data connection to the same participant or because the trigger pools in the other participants’ data store are not configured to respond to triggers from the local system.
