Receiving Data from OMRON PLCs using Ethernet
The CP1W-CIF41 Ethernet Option Board can only support receiving FINS
commands from OMRON PLCs using Ethernet.
Connecting within the
Same Segment
Use the UDP/IP version of the FINS communications service (i.e.,
FINS/UDP), and construct applications using the SEND(090), RECV(098),
and CMND(490) instructions in the ladder program. FINS/UDP is supported
by many OMRON products, and is compatible with earlier Ethernet Units
(CS1W-ETN01/ETN11/ETN21 and CJ1W-ETN11/ETN21). The protocol pro-
cessing for FINS/UDP is simpler than for FINS/TCP, giving FINS/UDP certain
advantages in terms of performance. Another feature of FINS/UDP is that it
can be used for broadcasting.
On the other hand, with FINS/UDP it is necessary to provide measures, such
as retries, for handling communications errors.
Connecting through
Multiple Segments
Use the TCP/IP version of the FINS communications service (i.e., FINS/TCP),
and construct applications using the SEND(090), RECV(098), and
CMND(490) instructions in the ladder program. FINS/TCP is the initial func-
tion supported by this Ethernet Option Board (CP1W-CIF41). It provides auto-
matic recovery at the TCP/IP layer from communications errors (such as
packet loss) that occur during multilevel routing.
