PROFINET Group Error

Hva betyr SF ?

This indicator signifies that PROFINET diagnostics are present, meaning at least one PROFINET device within the network is reporting a system error. The specific error priority can be further investigated using variables like PNIO_DIAG_AVAILABLE, PNIO_MAINTENANCE_DEMANDED, and PNIO_MAINTENANCE_REQUIRED. This status is also reflected by the PNIO_SYSTEM_SF system variable being TRUE.

• One or more configured PROFINET devices are indicating a system error (diagnostic alarm).
• One or more configured PROFINET devices are indicating a maintenance alarm (e.g., maintenance demanded or maintenance required).

1. 1

   Access the controller's diagnostic interface or monitor the PNIO_SYSTEM_SF variable to review detailed PROFINET diagnostics.

2. 2

   Identify the specific PROFINET device(s) that are generating diagnostic or maintenance alarms.

3. 3

   Check the system variables PNIO_MAINTENANCE_DEMANDED and PNIO_MAINTENANCE_REQUIRED to determine the priority of the maintenance alarm.

4. 4

   Use the RALRM diagnostic block (if supported) to identify the PROFINET device triggering the maintenance alarm.
