7.4.1 Socket interface communication
Information on the 8 user sockets of EN655 can be found in the module’s shared memory
space and can be read out using “MREAD” instruction. The following are included in the socket
interface information:
・Partner’s TCP/UDP port number
・Partner’s IP address
・Own TCP/UDP port number
・Socket status
The shared memory space is shown below. Refer to section 3.5.1 for EN655’s shared
