The CPE400 is programmed and configured over Ethernet via GE’s Proficy* Machine Edition (PME)
software. It is a stand-alone CPU with the following features:
• An OLED display that provides access to basic CPE400 status and control information.
• A micro-SD slot which may be used for program transfer and/or data collection. The slot is
protected by a cover that protects the memory card from ESD. This slot is not yet functional.
• A built-in RX3i PLC, supported by a dedicated microprocessor core.
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 512 program blocks. Maximum size for a block is 128KB.
• Supports four independent 10/100/1000 Ethernet LANs. Three are located on the front panel, as
shown in Figure 2. LAN1 attaches via the upper, dedicated RJ45 connector. LAN2 and LAN334
each attach via a pair of internally-switched RJ45 connectors. The fourth LAN, labeled EFA
(Embedded Field Agent), is an RJ45 port located on the underside (Figure 3), and is a dedicated
Field Agent port.
• The embedded communications interface is supported by a dedicated microprocessor core. This
dedicated processing capability permits the CPU to independently support LAN1, LAN2 and
LAN334 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.
• 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 – 512ms. I/O device update rates of 8ms and faster are possible with 16 or fewer devices.
Update rates of 16ms and higher result whenever more than 16 devices are configured.
• Embedded SNTP Client allows synchronization of the high-resolution Time of Day Clock to an
SNTP network time server.
• Field Agent permits the CPE400 to securely exchange data with the Predix™ Cloud, allowing
users to configure and view extensive data from an entire installation, such as a wind turbine
farm, within the Predix Cloud environment. This functionality is supported by two of the four
CPE400 microprocessor cores.
• Achilles Level 2 Communications Certification35
• Optional Energy Pack, IC695ACC403, allows CPE400 to instantly save user memory to nonvolatile storage in the event of loss of power. Upon restoration of power, with the ACC403
connected, the CPE400 PLC function is able to resume operations from the state saved at powerdown.
• Ability to display serial number and date code in PME Device Information Details
