•
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.
•
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 Enabled, Stop Enabled,
Run Disabled, Stop Faulted, and Stop Halted. The Sweep Time variable reports
the sweep time in seconds. These variables are located under
GE Device Information -> PACSystems RX3i -> Controller.
•
An OLED display that provides access to basic CPE400 status and control
information including each LAN's configured IP Address.
•
Operating temperature range -40C to 70C (-40F to 158F).
•
Alternate panel-mount adaptor plate included.
