CPE310 Fault Behavior when Configured as a CPU310  A CPE310 that is configured as a CPU310 logs the following faults in the Controller fault table on power up: - LAN Transceiver Fault is generated because the RX3i system detects that the embedded Ethernet module does not have a network connection. - An Extra Option Module fault is generated because the embedded Ethernet module is detected as an unconfigured module.  If the Energy Pack capacitor pack is disconnected or fails, the legacy faults for a missing or failed battery are logged.  When a CPE310 is configured as a CPU310, Ethernet properties cannot be configured and there should be no cable connected to the Ethernet port.  If a CPU310 configuration is stored to a CPE310, the RDSD port is enabled to allow you to transfer CPU310 projects to CPE310 models without using PME.

CPE310 versus CPU310 Performance Differences 

The following differences should be considered when converting legacy applications or developing new applications on the CPE310.  Some exceptionally lengthy CPE backplane operations, such as MC_CamTableSelect, Data Log and Read Event Queue functions, will take longer to complete compared to other RX3i CPU models, and may delay backplane operations to IC695 modules. For example, when an MC_CamTableSelect function block is executed on the PMM335 module, the CPU’s acknowledgement of the PMM355 module interrupt may be delayed. In this situation, you may see the following fault in the I/O Fault Table, even when the interrupt has not been dropped: Error initiating an interrupt to the CPU.  Performance specifications for many features, such as power-up time, function block execution times and I/O module sweep times have changed. For details, refer to Appendix A of GFK-2222R or later.  The RS-232 port on the CPE310 does not provide 5V power on pin 5.
