Function Description
Communications ---
Peripheral
(USB) Port
Peripheral Bus Bus for communications with various kinds of Support Software running on a
personal computer. High-speed communications are supported.
Serial Port
*4

Host Link (SYSWAY) Communications Host Link commands or FINS commands placed between Host Link headers
and terminators can be sent from a host computer or PT to read/write I/O mem-
ory, read/control the operating mode, and perform other operations for PLC.
No-protocol Communications I/O instructions for communications ports (such as TXD/RXD instructions) can
be used for data transfer with peripheral devices such as bar code readers and
printers.
NT Link Communications I/O memory in the PLC can be allocated and directly linked to various PT func-
tions, including status control areas, status notification areas, touch switches,
lamps, memory tables, and other objects.
Peripheral Bus Bus for communications with various kinds of Support Software running on a
personal computer. High-speed communications are supported.
Serial Gateway This gateway enables receiving and automatically converting FINS to the Com-
poWay/F.
Serial PLC Links
*5
Data is exchanged between CPU Units using serial ports without communica-
tions programming. PTs set to the 1:N NT Link protocol can be included in the
network.
EtherNet/IP Port
*6
100Base-TX/10Base-T
Protocols: TCP/IP, UDP, ARP, ICMP (ping only), BOOTP
Applications: FINS, CIP, SNTP, DNS (Client), FTP (Server)
