This is a sample program that issues the requests used with TCP sockets. It assumes that the parameter set up and operating mode control requests (run mode/socket interface transmission enable) have already completed.

a.TCP open request (passive)

This program issues a TCP open request (passive) for socket number 8 on the Ethernet Port.

This ladder program is executed by turning on the A contact on the R0630.

Parameters: 12544: 3100H, 00053: 0035H
