Backwards Compatibility of CPE310 with CPU310
The CPE310 may be swapped with a CPU310 with no upgrade to the Proficy Machine Edition Logic
Developer-PLC programming software. Logic and configuration equality in the programming software is
maintained when storing the same project to either a CPU310 or a CPE310. Proficy Machine Edition
versions that recognize the CPE310 (7.0 SIM3 and newer), allow either a CPU310 configuration or a
CPE310 configuration to be stored to the CPE310. For all programming software versions (both current
and legacy) a CPU310 device can accept only a CPU310 configuration.
Legacy CPU310 Projects
The CPE310 supports CPU310 projects. Proficy Machine Edition versions earlier than 7.10 SIM 3 interpret
the CPE310 as a CPU310. The CPE310 can be configured as a CPU310 using Proficy Machine Edition
versions as old as 5.5, Service Pack 1.
RDSD 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 Proficy Machine Edition.
Fault Behavior
Faults related to the embedded CPE310 Ethernet interface may be generated on power-up, as detailed
in the following section.
Replacing a CPU310 with a CPE310
▪
A CPE310 that is configured as a CPU310 logs the following faults in the Controller fault table:
A 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.
▪
When a CPE310 is configured as a CPU310, the Show Status dialog box in Proficy Machine Edition
displays CPU310A.
