OMRON FL-net Unit (100Base-TX) Features
High-speed
Communications at
100 Mbps A baud rate of 100 Mbps is supported. The baud rate can be automatically
selected or a fixed baud rate of 10 Mbps can be set.
Specify the Order of Data
Link Data The order of upper/lower bytes in data link data (word data) can be specified
for each node before sending or receiving the data, according to the specifica-
tions of the device connected in the data link.
FINS Message
Communications The FL-net Unit also supports FINS message communications, OMRON’s
standard communications service, so other OMRON PLCs can be accessed
by using SEND(090), RECV(098), and CMND(490) instructions in ladder pro-
grams. In addition, the FINS gateway function can be used to allow access to
other PLCs on not only the same FL-net network but also on other networks
such as Ethernet or Controller Link.
Controller Link Network
Connection Ethernet, the information-system network, can be connected to Controller
Link, the control-system network, using the FINS communications service.
This allows a PLC on the Ethernet or Controller Link network to be monitored
from an OMRON PLC on the FL-net network, and, conversely, for data to be
exchanged between a PLC on the Ethernet or Controller Link network and an
OMRON PLC on the FL-net network.
Abundant
Troubleshooting
Functions The Ethernet Unit is provided with a variety of troubleshooting functions for
prompt recovery in case of errors.
• Self-diagnostic function at startup
• PING command for checking other nodes
• Inter-nodal tests for checking other nodes
• Error log for recording error history data
