• In data sent/received in LAN communication, a header is attached to the MEWTOCOL-DAT
command data part, or the MEWTOCOL-DAT response data part, as indicated in the data
structure below.
• When the PLC side has the sending right, and executes the sending/receiving process, PLC
automatically attaches these data when SEND/RECV command is executed. Therefore, it is
not necessary to take account of these data in a user program.
