TCP cannot exceed more than 8 connections (or) up to 16 simultaneous SRTP

 Server connections (or) up to 8 simultaneous Modbus TCP Server connections.

o 8 Clients are permitted; each may be SRTP or Modbus TCP or a Combination of both.

o up to 8 simultaneous Class 1 Ethernet Global Data (EGD) exchanges.

o When used in combination for optimal performance, user must not exceed

4 Channels for Server (Modbus/SRTP) & 4 Channels for client (Modbus/SRTP),

8 PROFINET nodes and 8 EGD data exchanges.

 Ability to display serial number and date code in PME Device Information Details.

 Operating temperature range -40C to 70C (-40F to 158F).

User Features

The PACSystems* RSTi-EP EPSCPE100. is an enhanced performance standalone

1GHz programmable controller equipped with 1MB of user memory and four 

Ethernet ports to run real time deterministic control applications.

LAN1 is dedicated to highspeed Ethernet and LAN2 comprised of 3 switched ports

configurable as either an embedded Ethernet controller or an embedded PROFINET controller,

which provides the PROFINET functionality and supports only simplex mode of operation.

It is a standalone PLC that supports distributed I/O.

From now on in rest of the document this controller will be referred to as CPE100.

The CPE100 is programmed and configured over Ethernet via GE’s Proficy Machine Edition (PME)

software.

It can control/process up to 2K I/O points.

All four ports are located on the front panel, as shown in Figure 1.

 The embedded communications interface has dedicated processing capability,

which permits the CPU to independently support LAN1 and LAN2 with:

o up to 16 combined SRTP Server and Modbus TCP Server connections out of which Modbus 

TCP cannot exceed more than 8 connections (or) up to 16 simultaneous SRTP

 Server connections (or) up to 8 simultaneous Modbus TCP Server connections.

Features 

▪ Hot standby (HSB) redundancy. Two redundant units 

make up a redundancy system. Each unit requires one 

Redundancy CPU (IC695CRU320) and a redundancy 

Memory Xchange module (IC695RMX128/228) configured as a redundancy link. 

▪ Contains 64 Mbytes of battery-backed user memory and 

64 Mbytes of non-volatile flash user memory. 

▪ Provides access to bulk memory via reference table %W. 

▪ Configurable data and program memory. 

▪ Programming in Ladder Diagram, Structured Text, 

Function Block Diagram, and C. Refer to PACSystems RX7i 

& RX3i CPU Programmer’s Reference Manual, GFK-2950. 

▪ Supports auto-located Symbolic Variables that can use 

any amount of user memory. 

▪ Reference table sizes include 32Kbits for discrete %I and 

%Q and up to 32K words each for analog %AI and %AQ. 

▪ Supports most Series 90-30 modules and expansion 

racks. For a list of supported I/O, Communications, 

Motion, and Intelligent modules, refer to the PACSystems 

The PACSystems* RX3i Redundancy CPU can be used to 

perform real time control of machines, processes, and 

material handling systems. The CPU communicates with the 

programmer and HMI devices via a serial port using SNP 

Slave protocol. It communicates with I/O and smart option 

modules over a dual backplane bus that provides: 

▪ High-speed PCI backplane for fast throughput of new advanced I/O. 

▪ Serial backplane for easy migration of existing Series 90*-30 I/O.

Expansion Memory

The PCM can operate with or without an expansion

memory daughter board.  The base memory on the

PCM board has up to 95 Kbytes user memory.  The ex

pansion memory daughter board permits expansion of

program/data memory by 64. 128. 256 or 512 Kbytes.

The battery which supports this memory is located on

the base board housing as shown in figure 2.

• Installation should not be attempted without refer

ring to the applicable Programmable Controller

Installation Manual (see reference 5).

• Make sure rack power is off.

• Install expansion memory if required.

• Connect the battery to either of the battery con

nectors on the module. (See figure 2)

• Install in the rack. (See figure 1)

• Turn on power.

The module should power up and blink the top LED.

When the diagnostics have completed successfully the

top LED stays on.
