: This data length is defined by settings in SCONF instruction; for V1.06.20 or previous versions: 512 bytes are
available and for V1.06.30 or later versions: 4096 bytes are available.
3. When PLC CPU is from STOP to RUN, execute SCONF instruction. Refer to API 2209 SCONF for setting up the
socket.
4. Establishing a connection (Network 3); When M0 is ON, the system checks if the socket is closed (SM1274 = ON),
NOT connected (SM1270 = OFF), or NOT being connected (SM1273 = OFF). If the socket is not closed, has not
been connected, and is not being connected, the system performs the connection procedure. Once the socket is
connected (SM1270 = ON), M0 is switched to OFF.
