2 RSTi-EP EPSCPE100 Standalone CPU Quick Start Guide GFK-3012
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.

Features at a Glance
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.
Highlights include:
A built-in PACSystems RSTi-EP PLC CPU
o User may program in Ladder Diagram,
Structured Text, Function Block Diagram.
o Contains 1Mbytes of configurable data and
program memory.
o Supports auto-located Symbolic Variables that
can use any amount of user memory.
o Reference table sizes include 2k bits for discrete
%I and %Q and up to 2k words each for analog
%AI and %AQ. Bulk memory (%W) also
supported for data exchanges.
o Supports up to 512 program blocks. Maximum
block size is 128KB.
Supports two independent 10/100 Ethernet LANs. LAN1 has only one port and is
dedicated to highspeed Ethernet and whereas LAN2 comprises of 3 switched
ports configurable as either an embedded Ethernet controller or an embedded

PROFINET controller. 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.
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 -40C to 70C (-40F to 158F).

1.1. Membrane Run/Stop push button
Pressing Membrane Run/Stop push button briefly, will change the
state of CPU from the state it is in to the next state. Switch operation
state as given in the following state diagram:
The Run/Stop switch is enabled by default; it can be disabled in PME Hardware
Configuration (HWC) settings.

PLC has passed its power-up diagnostics and is
functioning properly
Power is not applied or PLC has a problem.
Blinking; All
other LEDs
off
PLC in STOP/Halt state; possible watchdog timer fault.
If the programmer cannot connect, cycle power and
refer to the fault tables.
Blinking; All
other LEDs
off
Indicates that PLC has encountered a fatal error and is
blinking the error code.
PLC is in STOP/Faulted mode: a fatal fault has
occurred.
No fatal faults detected.
1.2. LED Indicators (LEDs)
Ethernet Status Indicators
There are two LEDs (Yellow/Green) for each Ethernet ports of LAN1 and LAN2, which
are embedded in the RJ-45 connectors. The green LED indicates an Ethernet
connection has been established. The yellow LED indicates packet traffic.
Module status Indicators
There are three LEDs and one Membrane Push Button on the front panel
(The one in blue color) as shown in the figure. The below table describes
the behavior of each module LED:
Push Button: Toggles the current mode of the PLC.

1.3 Ethernet Ports
LAN 1 connects to the uppermost RJ-45 connector. It is not switched. LAN2 connects
to the three lower RJ-45 connectors. They are switched internally.
The embedded Ethernet interfaces automatically senses the link data rate (10 Mbps or
100 Mbps), communications mode (half-duplex or full-duplex), and cabling
arrangement (straight-through or crossover).
The embedded Ethernet LAN 1 port may be used to communicate with PME
programming software using the Service Request Transport Protocol (SRTP, a
proprietary GE protocol, used primarily for communication with the programmer).
To establish Ethernet communications between the PME programming package and
the CPU, you first need to set an IP address.
Note: LAN2 will not be operational unless it is configured from the programmer with a
valid IP address.
A typical application will take advantage of the two independent LANs. The dedicated
LAN 1 port will be used for communications with plant-level or supervisory layers. The
