Rackless CPU with Field Agent Quick Start

User Features

The PACSystems™ RX3i CPE400. part of Emerson’s Industrial Internet

Control System, is the industry’s first outcome optimizing controller. It

augments real-time deterministic control with Field Agent technology,

delivering near real time advice through market analysis, fleet and

enterprise data, or asset/process knowledge to optimize the outcomes that

today’s businesses require. The Predix™ enabled CPE400 provides reliable,

secure communication and analytics using either cloud-based or edge

based outcome optimizing apps. Controls can now be programmed to

dynamically influence business outcomes, generate new forms of revenue,

and improve profitability.

▪ The stand-alone CPE400 uses a 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.

o A built-in RX3i PLC:

o User may program in Ladder Diagram, Structured Text, Function Block

Diagram, or C.

o Contains 64Mbytes 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 32k bits for discrete %I and %Q and up to

32k words each for analog %AI and %AQ. Bulk memory (%W) also

supported for data exchanges.

o Supports up to 768 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 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:

o 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

10 concurrent variable subscriptions and up to 12.500 variables;

o up to 255 simultaneous Class 1 Ethernet Global Data (EGD)

exchanges.

o DNP3 Outstation support with up to 8 master client connections

▪ The embedded PLC may use one or both of the Ethernet LAN2 ports to

support the embedded Simplex PROFINET I/O Controller. PROFINET

supports up to 32 I/O devices with update rates of 1 – 512 ms. I/O device

update rates of 8 ms and faster are possible with 16 or fewer devices.

Update rates of 16 ms and higher result whenever more than 16 devices are

configured.

Media Redundancy Protocol (MRP) allows the CPE400 to participate in a

PROFINET I/O network with MRP ring technology. This eliminates the I/O

network as a single point of failure. The CPE400 may be used as either a

Media Redundancy Manager or Media Redundancy Client.

▪ Effective with firmware release 9.30. the CPE400 supports Hot Standby

Redundancy with PROFINET IO. In this configuration, LAN3 is used as a high

speed data synchronization link between the two redundant CPUs. Only the

Primary and Secondary CPUs may be attached to LAN3. Two OLED menu

items support Redundancy operation: RDN Info and RDN Command. The

RACT and RBOK LEDs reflect the status of the Redundant CPUs.

▪ Effective with firmware release 9.30. the CPE400 supports two independent

Redundant IP addresses, one for LAN1 and one for LAN2. LAN2 Redundant

IP is supported when configured for Ethernet mode only. Redundant IP is

supported by the SRTP Server, Modbus TCP Server, and EGD protocols. It is

not possible to use Redundant IP with the OPC UA Server or with the

Ethernet firmware update web page.

▪ The CPE400 is secure by design, incorporating technologies such as Trusted

Platform Modules, secure boot, and encrypted firmware updates.

▪ Optional Energy Pack, IC695ACC403. allows CPE400 to instantly save user

memory to non-volatile storage in the event of loss of power.

▪ OPC UA Sweep Mode & Sweep Time: The CPE400’s sweep mode and

sweep time are available through the OPC UA server. The Sweep Mode

variable reports the controller’s current mode: Stop Disabled, Run Enab
