PACSystems RX3i User Manual

GFK-2419M
March 2009
The PACSystems RX3i Ethernet NIU, IC695NIU001,
makes it possible to use PACSystems RX3i and Series
90-30 I/O remotely on an Ethernet network. Once set up
by configuration, data exchange is completely automatic.
System control can be provided by any GE Fanuc master
device capable of exchanging Ethernet Global Data. The
Ethernet NIU automatically provides the controller with
status information in each exchange. The application
program logic in the controller can monitor this status data,
and issue appropriate commands to the Ethernet NIU.
An RX3i Ethernet NIU station consists of:
▪
an RX3i Universal Backplane (IC695CHS0xx)
▪
an RX3i power supply (IC695PSxxxx)
▪
the RX3i Ethernet NIU (IC695NIU001)
▪
one or more RX3i Ethernet modules (IC695ETM001)
▪
proprietary application software
▪
Optional Series 90-30 expansion backplanes.
▪
PACSystems RX3i and/or Series 90-30 modules, as
appropriate for the application.
The Ethernet NIU is compatible with the same types of
modules, backplanes, and other equipment as a
PACSystems RX3i CPU. For a list of compatible products,
see the PACSystems RX3i Hardware and Installation
Manual, GFK-2314.
This module requires Machine Edition Logic Developer
software, version 5.51 or later.
Ethernet NIU Features
▪
20Kbytes of optional local logic. Supports all
languages except C programming.
▪
10 Mbytes of built-in flash memory for local user data
storage.
▪
Battery-backed calendar clock.
▪
In-system upgradeable firmware.
▪
Two serial ports: an RS-485 serial port and an
RS-232 serial port.
▪
Supports Ethernet communications via the backplane-
based Ethernet Interface module (IC695ETM001)
▪
Data exchange using Ethernet Global Data (EGD)
▪
TCP/IP communication services using SRTP
▪
Comprehensive station management and diagnostic
tools
▪
Supports operation with redundant controllers
PACSystems™ RX3i
Ethernet Network Interface Unit
▪
PACSystems RX7i and RX3i controllers can send
selected COMMREQs to the RX3i ENIU via Ethernet
Global Data. The ENIU executes the COMMREQs and
returns the results to the controller.
▪
During EGD configuration, RX3i Ethernet interfaces are
identified by their Backplane/Slot location.

Ethernet Global Data Features
The Ethernet NIU communicates with its controller via
Ethernet Global Data exchanges. One exchange is used to
send outputs to the ENIU and another exchange is used to
send inputs back to the controller. The ENIU supports
receiving outputs from redundant controllers. By sending the
EGD exchange to a group address both controllers can
receive the inputs. Up to 1300 bytes of outputs can be sent to
a set of ENIUs from a controller. Each ENIU can send up to
1300 bytes of inputs to the controller.
A typical system might consist of a controller with five ENIUs.
The controller sends 1300 bytes of outputs and each ENIU
