Ethernet IP

Main features & Overview

Visión general

The communication module GFX4-ETH1/ETH5 / ETH8 can be installed inside GFX4-GFXTERMO4/GFX4-IR or GFW products and expands communication by means of the Ethernet IP protocol (where the different versions follow the evolution of the stack versions and the Conformance Tests).

The module has two communication channels:
• Ethernet (switch) 2 port
• Modbus Master: allows communication with a maximum of 4 slave devices
The expansion can be installed when the above-mentioned products are ordered or installed at a later date (by expert personnel).
«E8» is the latest version, ODVA certified and compliant with Conformance test 15 ( C.T.15)

«E5» is the latest version with capability to manage «Implicit Messages» DLR function and EDS files, compliant with Conformance test 9 ( C.T. 9 )
«E1» is the previous version that is MANDATORY for replacements of existing projects developed with «E1» board.

The GFX4-ETH1/ETH5/ETH8 cards CANNOT be inserted in GFX4 and GFXTERMO4 products equipped with the 4 auxiliary inputs option (mV/TC Aux).
