Overview
The CANopen X80 master modules (BMECXM) provide access to CANopen bus on a M580 PAC.
Ruggedized Version
The BMECXM0100H (hardened) equipment is the ruggedized version of the BMECXM0100 (standard) equipment. It can be used at extended temperatures and in harsh chemical environments.
For more information, refer to chapter Installation in More Severe Environments.
NOTE: In Control Expert, there is only one device part number BME CXM 0100 in the Hardware Catalog to declare and configure both CANopen X80 master module references.
Altitude Operating Conditions
The characteristics in the tables below apply to the modules BMECXM0100 and BMECXM0100H for use at altitude up to 2000 m (6560 ft). When the modules operate above 2000 m (6560 ft), apply additional derating.
For detailed information, refer to chapter Operating and Storage Conditions.

Backplane Connector Connection
The Ethernet bus interface at the back of the BMECXM module connects to the Ethernet backplane connector when you mount the module in the rack.
The module is powered by the backplane. It is hot swappable, that is, it may be installed and uninstalled without turning off the power supply to the rack.
The X Bus connector of the backplane is not used by the module as it is an Ethernet only module.
The module uses the Ethernet bus on the Ethernet backplane to manage the connectivity to the Ethernet I/O scanner.
The module can be managed by:
The module communicates with a PC that is connected to the Ethernet network using an asset management, a network manager, or a web browser.
