Genius Global Data

The Series 90-30 PLC supports very fast sharing of data between multiple CPUs using Genius global data. 

The Genius Bus Controller, IC693BEM331 in CPU, version 5 and later, and the Enhanced Genius Communications Module,

IC693CMM302, can broadcast up to 128 bytes of data to other PLCs or computers. 

They can receive up to 128 bytes from each of the up to 30 other Genius controllers on the network. 

Data can be broadcast from or received into any memory type, not just %G global bits.

The original Genius Communications Module, IC693CMM301, 

is limited to fixed %G addresses and can only exchange 32 bits per serial bus address from SBA 16 to 23.

For new installations, we recommend this module not be used; 

instead, use the newer enhanced GCM, which has considerably more capability.

Global data can be shared between Series Five, Series Six, and Series 90 PLCs connected to the same Genius I/O bus.

Ethernet Communications

The Model 364 CPU (release 9.0 and later) supports connection to an Ethernet network through either (but not both) of two built-in Ethernet ports. 

AAUI and 10BaseT ports are provided. 

The Model 374 CPU supports connection to an Ethernet network through two built-in 10BaseT/100BaseTx auto-negotiating full-duplex Ethernet ports.

Both the CPU364 and CPU374 support Ethernet Global Data (EGD), which is similar to 

Genius Global Data in that it allows one device (the producer) to transfer data to one or more other devices (the consumers) on the network.

EGD is not supported by Logicmaster 90 software (requires a Windows-based programmer for Series 90 PLCs.)

Overview

The built-in enhanced Ethernet interface of the Series 90-30 CPU374 PLUS provides TCP/IP  communications with: 

▪ Series 90, PACSystems, and VersaMax PLCs

▪ host computers running the Host Communications Toolkit or CIMPLICITY software

▪ computers running the TCP/IP version of the programming software.

These communications use the GE Fanuc SRTP and Ethernet Global Data (EGD) protocols

over a four-layer TCP/IP (Internet) stack.  The Ethernet interface has SRTP server capability.

As a server, the Ethernet Interface  responds to requests from devices such as PLC programming software, 

a Host computer  running an SRTP application, or another PLC acting as a client.

Series 90-30, 90-20, and Micro I/O System

The PLC I/O system provides the interface between the Series 90-30 PLC and user-supplied

devices and equipment. Series 90-30 I/O modules plug directly into slots in Series 90-30 baseplates. 

The number of Series I/O modules supported depends upon the CPU model:

• CPU models 350—374 support up to 79 I/O modules. These CPUs support up to eight racks,

which includes the CPU rack plus a total of seven expansion and/or remote racks.

• CPU models 331, 340, and 341, support up to 49 I/O modules. These CPUs support up to five

racks, which includes the CPU rack plus a total of four expansion and/or remote racks.

• CPU models 311 and 313 (5-slot baseplates) support up to 5 Series 90-30 I/O modules. 

CPU model 323 (10-slot baseplate) supports up to 10 Series 90-30 I/O modules. 

These three CPUs do not support expansion or remote racks.

The I/O structure for the Series 90-30 PLC is shown in the following figure.

Introduction

The PACSystems RX3i family provides advanced diagnostics and high performance I/O.

With a modular design and multiple expansion options, RX3i is the perfect I/O solution for your process, hybrid,and discrete applications.

Modular, High-Speed Performance RX3i is a rack-based system with a wide range of modules covering digital, analog, and numerous other specialty

I/O types. These pluggable and hot-swappable modules allow you to customize the right mix of I/O, 

with a variety ofvoltage ranges and current capacities supported to meet all your application needs.

Regardless of the I/O mix you choose, RX3i is built on high speed interfaces to provide rapid and consistent data transfer.

Two LEDs on the Mini Converter indicate activity on the transmit and receive lines.

The Converter Plug is required to convert the 9-pin serial port connector on the Mini Converter to

the 25-pin serial port connector on an IC647 computer, an IBM® PC-XT, or a PS/2® Personal Computer.

The IC640 industrial computer requires an additional adapter (not supplied – please contact your local PLC distributor) for use with the Mini Converter.

Tables 1 and 2 list the Mini Converter pinouts. The direction of signal flow is with respect to the Mini Converter.

The Series 90-30, 90-20, and Micro PLCs are members of the GE Fanuc Series 90 family of Programmable Logic Controllers (PLCs). 

They are easy to install and configure, offer advanced programming features, and are compatible with the Series 90-70 PLCs.

The 341 and lower Series 90-30 PLCs and Series 90-20 PLC use an 80188 microprocessor.

The 35x and 36x series of 90-30 PLCs use an 80386EX microprocessor. 

The 37x series of 90-30 PLCs use a 586 microprocessor. 

The Series 90 Micro PLC uses the H8 microprocessor. 

Both program execution and basic housekeeping tasks such as diagnostic routines, input/output scanners, and alarm processing are supported.
