Issue
On the current M580 CPU FWs the syslog messages sent by the CPU are not aligned with the Syslog messages documented in the reference Manual : Modicon Controllers Platform - Cyber Security - Reference Manual ( EIO0000001999.06 )
Customer wants to know what are the syslog message list generated by the M580 CPU.

Product Line
M580 CPU HSBY and Standalone.
Only Standalone Syslog Event messages will be available. No specific HSBY Syslog event messages are currently available.

Environment
Firmware 3.10

Resolution
The Syslog M580 CPU syslog messages – V2.pdf document contains the Syslog messages generated by the CPU syslog and sent to a syslog server.

Here is below the legend to read the document (extract from the document: Modicon Controllers Platform - Cyber Security - Reference Manual: EIO0000001999.06)
