1-1-1 Overall System Configuration Example
The following diagram shows an example of an overall system configuration
using Ethernet Units.
1-1-2 Determining the Objectives
Connecting the CX-Programmer to PLCs Online via Ethernet
Connecting within the
Same Segment Use the UDP/IP version of the FINS communications service (i.e., FINS/
UDP). FINS/UDP is supported by many OMRON products and is compatible
with earlier Ethernet Units (CS1W-ETN01/ETN11 and CJ1W-ETN11). The
CX-Programmer can be connected and used with FINS/UDP even if personal
computer middleware (FinsGateway) is not used. FinsGateway (any version)
can also be used together with the CX-Programmer.
