[Cause]
The issuance of DCS-related alerts led to the issuance of this alert in order to establish FL-net-based security features as a security site. Or a communication error was detected in a security function based on FL-net.
[Countermeasure]
This may also be the case when other DCS-related alerts are issued. Please first remove the reason before restarting. If no other DCS-related alert is sent, confirm the connection and settings for FL-net-based security features.
