SIMATIC S7 PROTOCOL SUITE

Hi everyone!

   I have interrupted TCP connection between WinCC worktation and S7-400 every 2-3 sec. I checked Ethernet and it is ok. But in a log file (SIMATIC_S7_PROTOCOL_SUITE_02.LOG) I have found an error: Errorcode 0xFFDF 011F. Could someone explain what this error means? I have not found such error code in an error description:

Hi, neur0b0t

Try to check your connection while runtime using WinCC Channel Diagnosis. The tool can be found here: 

Start > Siemens Automation > SIMATIC > WINCC > TOOLS > Channel Diagnosis

The list of error codes for WinCC Channel Diagnosis can be found here (by search phrase "Error codes"):

Hello neur0b0t,

the Errorcode 0xFFDF 011F means: "Application buffer too small".
The "Application" is the process, which would get the data.
Maybe there is something wrong in the structure/length of the
telgram.
Do you work in the PLC with special function-blocks, which
may be configured wrong ?

  Hello Mr. Berghof,

  I work with two S7-417 5H PLC which are connected with redconnect application. In addition, my PLCs have many different kinds of special function blocks. Maybe, you could give a piece of advice how to find the source of troubles? This error happens one time a week and continues until PLC resets.

Thanks,

Basil.
