GE PACSystems RX3i CPE400 Quick Start Manual page 6

•
The stand-alone CPE400 uses a 1.2GHz quad-core microprocessor and real-time
hypervisor technology to run real time deterministic control applications
concurrently with Field Agent technology without any adverse impact of one
over the other.
•
A built-in RX3i PLC:
User may program in Ladder Diagram, Structured Text, Function Block
o
Diagram, or C.
Contains 64Mbytes of configurable data and program memory.
o
Supports auto-located Symbolic Variables that can use any amount of user
o
memory.
Reference table sizes include 32k bits for discrete %I and %Q and up to 32k
o
words each for analog %AI and %AQ. Bulk memory (%W) also supported for
data exchanges.
Supports up to 512 program blocks. Maximum size for a block is 128KB.

•
Field Agent technology is a platform for securely applying Predix applications
and secure connectivity to the Predix Cloud as well as running edge apps.
Running the Field Agent concurrently with the real-time control applications
allows the CPE400 to rapidly leverage external data. External monitoring may be
used to analyze and optimize entire business operations. The analysis can then
be used to dynamically adjust real-time industrial controls to align with changing
business objectives in today's Industrial Internet age.
•
Supports four independent 10/100/1000 Ethernet LANs. Three are located on the
front panel, as shown in Figure 1. LAN1 attaches via the upper, dedicated RJ 45
connector. LAN2 and LAN3 each attach via a pair of internally-switched RJ 45
connectors. The fourth LAN, labeled EFA (Embedded Field Agent), is located on
the underside (Figure 2), and is specifically used for Field Agent connectivity (see
Field Agent bullet just above).
•
The embedded communications interface has dedicated processing capability,
which permits the CPU to independently support LAN1 and LAN2 with:
up to 48 simultaneous SRTP Server connections;
o
up to 16 simultaneous Modbus/TCP Server connections;
o
32 Clients are permitted; each may be SRTP or Modbus/TCP.
o
OPC UA Server with support for up to 5 concurrent sessions with up to
o
10 concurrent variable subscriptions and up to 12,500 variables;
up to 255 simultaneous Class 1 Ethernet Global Data (EGD) exchanges.
