About OMRON TCP/IP Communications

The OMRON® TCP/IP Communications enabler supports CV-Series programmable controllers in multi-drop configurations with the OMRON TCP/IP Communication Enabler acting as the master. The OMRON TCP/IP Communications provides read and write access to the OMRON programmable controllers via TCP/IP over an Ethernet network. The CV-Series controller(s) must be equipped with OMRON Ethernet Module(s).

The OMRON TCP/IP Communication enabler supports the CV-mode protocol and command set, also referred to as FINS. The FINS commands are sent in Ethernet UDP datagram transactions. The enabler uses FINS commands to communicate directly with OMRON CV-Series programmable controllers.

FINS commands also allow inter-network communications to networked OMRON programmable controllers. In this configuration, a CIMPLICITY project communicates to C- or CV-Series programmable controllers via a primary CV-Series programmable controller that acts as a gateway to other networks such as SYSMAC Net and SYSMAC LINK Net.

All communication commands are implemented as master/slave communications where the OMRON TCP/IP Communications enabler acts as the master responsible for requesting data from or writing data to OMRON programmable controller(s). Unsolicited data sent from OMRON programmable controllers is not supported.

This enabler supports the following CIMPLICITY features:

Polled reads at user defined rates

Poll after setpoint

Triggered reads

Analog deadband

Alarm on communications failure

Server Redundancy configurations

This enabler supports the following data types:

Signed 8, 16, and 32 bit integers

Unsigned 8, 16, and 32 bit integers

Floating point
