When capturing via TCP/IP sequence errors and incomplete telegrams occur. What might be the cause for that error?


These kinds of errors can have the following causes:

  • The sender sends the telegrams faster than the ibaPDA acquisition time base or the network are designed for. This is why telegrams go lost or arrive fragmented.
  • Different TCP/IP protocol versions on ibaPDA-PC and sender concerning acknowledgment handling. For further information please consult the "ibaPDA-Interface-S7-TCP/UDP" manual.
  • Use UDP/IP protocol instead. Because of how it works sequence errors can not happen.
