Hello Dmitriy,

Errorcode 0xFFDF 410E! means:

Connection was aborted:
- AS or CP disabled or reset.
-AS not connected to bus or error in bus system.
-Number of maximum permitted connections in AS exceeded.

Errorcode 0x0000 7002! means:
Lifebeat acknowledgement error.
The connection was terminated because the acknowledgment
of the lifebeat frame was not received within the expected period.

Here you can try to increase the values for the lifebeat monitoring
in the systemparameter of the channel (see screenshot).
But the networkconnection may be slow for any reason.

Regards

Hi AutoGen_1959454

Error codes of a connection failure

Search in the WinCC online help for "Error codes of a connection failure"

or open the help file "S7CHNERRORDEU.HLP" with the error codes directly under the WinCC installation path e.g .: C: \ Programs \ Siemens \ WinCC \ bin.

or S7DOS error codes under "Error codes in the event of a connection failure"

see also

What do the entries in the WinCC diagnostics file "SIMATIC_S7_PROTOCOL_SUITE_01.LOG" mean in the case of a connection fault?
