S5-2 Transmission Data Format of Commands

The transmission data consists of "TCP/IP header part," "Protocol header part," and "Command part" (request command and
response command). The format is the same for both request command and response command. The data are all binary codes
(not ASCII codes).
Usually, the user needs to pay attention when sending or receiving "Protocol header part," and "Command part." Since the
Ethernet communication driver automatically attaches "TCP/IP header part," the user does not need to pay attention to it.
