Description
The B&R Automation 4IF370.7 is a plug-in communication interface module designed for the Power Panel 15, 21, 35, and 41 HMI/controller series. The unit equips the parent Power Panel with one electrically isolated CAN network interface. This enables network-capable integration with distributed I/O blocks, servo drives, and other industrial field nodes via standard CANopen or proprietary CAN layer-2 communication architectures.

Field Integration & System Engineering Constraints
1. Slot Mechanical Alignment
The 4IF370.7 is styled as an unshielded internal PCB assembly featuring an attached narrow metal faceplate panel. It slides directly into the backend option slots of compatible B&R Power Panel touch terminals. Ensure the guiding tracks line up accurately during insertion to prevent misalignment of the multi-pin edge pin header. Hand-tighten the retention screws to achieve proper system grounding across the chassis.
2. Network Topology and Termination
When configuring the CAN bus network, termination resistors (120\ \Omega) must be placed at both physical ends of the trunk line to absorb reflection signals. Failure to terminate the ends properly causes network packet collisions, packet dropouts, or cyclic bus-off failures inside the B&R Automation Studio diagnostics tool.
3. Electrical Isolation Compliance
The onboard electrical isolation safeguards the main Power Panel processor circuitry from high-voltage spikes, transient noise, and earth loops originating in field wiring channels. Always separate the CAN signal cables from heavy AC power conduits (e.g., 480 V motor circuits) to keep data transmission errors to a minimum.
System Safety Constraint: Never attempt to install or uninstall the 4IF370.7 module while the parent Power Panel terminal is connected to an active power line. Hot-plugging the interface card will blow internal logic fuses or permanently corrupt the backend option bus controller.
Frequently Asked Questions
Which specific firmware versions support the 4IF370.7?
The 4IF370.7 is fully native to B&R Automation Studio V2.x and V3.x environments. When replacing older revisions or migrating settings, the system configuration profile handles the mapping. Ensure that the corresponding hardware topology file (.hwx) matches this exact model number string.
Can this module operate as a CANopen Master?
Yes, depending on how the application project is configured in Automation Studio, the 4IF370.7 can function either as a CANopen Master or a CANopen Slave node, or process generic raw CAN identifiers using custom software blocks.
What should I check if the CAN communications fail to initialize?
Verify the power network state first. Then check that the physical baud rate settings configured in your software match the physical length limitations of your cable layout. Finally, confirm that the ground pin of the network connector is bound to a clean reference point to stabilize signal levels.
