IEC 60870-5-104 protocol, error in log file.

[SergLSV]

In the log file for the channel used for communication via the IEC 60870-5-104 protocol, I am constantly encountering the error 'Tx 16 bytes at 26-NOV-2024 06:58:02.557 to "IEC104.Direct Outstation 3" SCN(Error Response)'. What does this error mean, and does it affect the quality of communication via the protocol? I`m using Geo SCADA Expert 2020

No reply to this yet? My only suggestion is to look at the protocol comms log and show it to a 61850 expert.
