Chapter 2. CPU Features & Specifications
Energy Pack Connector
The CPE400 compatible Energy Pack, IC695ACC403, is supplied with a purpose-built cable which installs
in the connector shown in Figure 3.
Use of the Energy Pack is optional. Once charged up, the ACC403 allows the CPE400 to instantly save
user memory to non-volatile 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
power-down.
Refer to the PACSystems RX3i Rackless Energy Pack IC695ACC403 Quick Start Guide, GFK-3000, for
complete wiring and grounding instructions.
Note that the connector shown in Figure 3 is not supplied with the CPE400.
Input Power Connector
If no Energy Pack is to be connected, refer to Section 2.4 of the RX3i IC695CPE400 1.2GHz 64MB Rackless
CPU w/Field Agent Quick Start Guide, GFK-3002. Otherwise, refer to the PACSystems RX3i Rackless
Energy Pack IC695ACC403 Quick Start Guide, GFK-3000,
Backwards Compatibility of CPE400
In Proficy Machine Edition, the CPE400 is identified as a PLC within the PACSystems RX3i Rackless
family. To convert an existing project which uses any other PLC, use the Family Conversion feature in
PME. Be aware of the constraints involved. For instance, the first PROFINET Controller in an RX3i CPU320
application will be assigned to the Embedded PROFINET Controller feature (refer to Section 2.1.6) of the
CPE400.
