PROTOCOL-SPECIFIC INFORMATION
• No explicit module selection is required on the interface card: the module will be selected
automatically according to the controller’s configuration.
• If a timeout (communication loss) occurs on the RT connection, the driver can be configured to
perform a timeout action. The timeout value is dictated by the PROFINET controller and is at least
three times the IO Cycle update time. The timeout value is also known as the “IO Cycle Watchdog”
time.

Device Name
The device name / station name must be unique across the entire PROFINET network, because it is
used by controllers to uniquely identify PROFINET devices. This string must conform to the device name
requirements contained in the PROFINET specification.
9.9.3 Connection Timeout Options
In the studio’s Project panel, navigate to A7NETH-2P…Ethernet…PROFINET IO. The following
configuration options will determine the actions to be taken by the card if the PROFINET IO connection
is abnormally terminated or lost.
