Detailed Description

Declares the PROFINET RTA alarm listener and AlarmAck transmission support.

Provides asynchronous reception of PROFINET alarm notifications, parsing of RTA alarm frames, duplicate handling, callback dispatch, and transmission of the corresponding AlarmAck frames. Background alarm reception for an established AlarmCR connection. Receives AlarmNotification PDUs from a device (Layer 2 RTA-PDU or UDP), parses them, sends AlarmAck-PDU back, and invokes registered callbacks.

Per IEC 61158-6-10:

• Alarms are sent via Layer 2 (RTA-PDU, EtherType 0x8892) or UDP
• Controller must acknowledge each alarm with AlarmAck-PDU
• Frame IDs: 0xFC01 (high priority), 0xFE01 (low priority)
