12.3 Interfaces

The Power Panel has two interfaces:

12.3.1 CAN Interface

The electrically isolated standard fieldbus interface is used for the following tasks:
• Communication with other control systems
• Decentralization and remote I/O expansion using B&R 2003 components and a CAN bus
controller
We recommend using the AC911 T-connector for coupling to a CAN network. A terminal
resistance is integrated into the T-connector for the bus termination, which can be switched on
or off. For more information on wiring CAN fieldbus systems, see chapter 2, "Installation", section
"CAN Fieldbus" in the B&R SYSTEM 2003 User's Manual.
