CJ2 CPU Unit Hardware User's Manual
---
Bus for communications with various kinds of Support Software running on a
personal computer. High-speed communications are supported.
---
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.
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.
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.
Bus for communications with various kinds of Support Software running on a
personal computer. High-speed communications are supported.
This gateway enables receiving and automatically converting FINS to the Com-
poWay/F.
*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.
100Base-TX/10Base-T
Protocols: TCP/IP, UDP, ARP, ICMP (ping only), BOOTP
Applications: FINS, CIP, SNTP, DNS (Client), FTP (Server)
Programless cyclic data exchanges with the devices on the EtherNet/IP net-
work.
Any CIP commands can be received from the devices on the EtherNet/IP net-
work.
Any FINS commands can be transferred with the devices on the EtherNet/IP
network.
