Greetings to all,

I am currently using a CP-8050 (172.16.1.20), I am trying to synchronize it to a SCADA (172.16.1.50) system, which works as an IEC-104 master. After reading the manual, it seems like the master sends a command containing the new time as a payload, and the RTU uses it to modify its timestamp, and sends an AKC message. The only configuration to achieve this should be: RTU Settings - Topology - Clock sync: Receive Only; and Systems Settings - Sync of the device: Automatic.

Now, using Wireshark I can see that the master is in fact sending the sync command to the RTU, but its time is not changing at all.

What could I be missing? Attached in the link below are the packet trace and screenshots.

Hello Plink159,

Could you please reattach the trace and screenshots? There seems to have been a problem with the link.

Best regards

Hello Tarwar, I posted the question yesterday from another account since I could not access mine.
