1. 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.
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.

Features at a Glance
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 -40 C to 70 C (-40 F to 158 F).
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:
RUN/IO STOP/IO
Enabled Disabled
The Run/Stop switch is enabled by default; it can be disabled in PME Hardware Configuration (HWC) settings.

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.
LED |

Operating State |
|
OK |
On Green |
PLC has passed its power-up diagnostics and is |

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.

LAN2 |
Default IP Address: |
192.168.0.100 |

Subnet Mask: |

Gateway: |

0.0.0.0 |
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
