Is the FETCH / WRITE protocol in the data structure of COTP?

Where can I find it ? is it in the step 7 directory installation? The PLC ETHERNET communication between S300 and S400 is made with BSEND and BRCV blocks and when I sniff the ETHERNET link with Wireshark I see request and response with TCP + TPKT + ISO 8073 COTP + Data beginning with Ox32. Is the FETCH/WRITE protocol in the data structure of COTP? Best regards Maurice
