Program example
● After confirming that the Ethernet initialization active flag (X61) is OFF, the instruction is
executed.
● The UNITSEL instruction is used to specify a slot number (LAN port: U100) and a connection
number (U1 to U16).
● Once the instruction is executed, the IPv4 setting parameter will be written into the system
work area, and initialization will be requested to the unit.
● Once initialization is requested, the unit will close all connections and disconnect
communication.
● The unit turns OFF the IP address established flag (X62) and initializes the Ethernet unit with
the value specified in the system work area.
● The unit starts auto negotiation at the time of initialization.
● The IP address established flag (X62) turns ON upon the completion of initialization. It takes
about three seconds to complete initialization.
● Each communication task of FTPc, HTTPc and SMTPc starts according to the settings. It is
possible to confirm those states with the ready flag for each operation.
● Each connection which automatic connection has been set is made, and the clear to send
flag turns ON when the connections are complete.
