Description
The B&R 8I0IF108.400-1 is an industrial Ethernet communication expansion module specifically engineered for the ACOPOSinverter P74 and P74new variable frequency drive (VFD) platforms. It provides a high-speed, deterministic dual-port POWERLINK V2 network interface, enabling real-time motion control coordination, synchronization, and comprehensive parameter diagnostics from a centralized B&R PLC system over a structured Ethernet bus architecture.

Field Engineering & Integration Notes
In field deployments across high-performance packaging, printing, and CNC motion systems, the 8I0IF108.400-1 is inserted directly into the designated option slot of the ACOPOSinverter P74 housing. The dual RJ45 interface configuration features an integrated hub that supports daisy-chain line topologies, minimizing field cabling runs by eliminating the need for localized external managed Ethernet switches.
During a 2 AM commissioning cycle or network topology alteration, field engineers must note that this module arrives with pre-installed firmware. The module’s active runtime environment is managed directly by the B&R Automation Runtime operating system on the master controller. If a firmware version mismatch is detected between the VFD interface option card and Automation Studio, the PLC will automatically push an updated runtime patch to the module over the network.
Important Field Caveat: Legacy ACOPOSinverter P74 hardware revisions (specifically version A0) require a complete cold hardware power cycle (de-energizing main and auxiliary supply power) after a module firmware update to correctly initialize the updated registers.

Protocol & Automation Studio Configuration
Configuration is executed within B&R Automation Studio. The hardware profile must be added to the physical configuration tree under the respective slot configuration for the P74 drive:
- Station Addressing: Node addresses are set electronically through the drive parameters via the HMI keypad or software mapping, matching the project’s hardware topology rules.
- Cyclic Data Mapping: Allows real-time mapping of critical motion parameters, including Target Velocity, Actual Velocity, Control Word, Status Word, and Torque Limits, directly into the PLC’s cyclic tasks (Task Class 1 or 2).
Frequently Asked Questions
- Q: Can this module be hot-swapped while the ACOPOSinverter is powered up?
- A: No. Installing or removing the 8I0IF108.400-1 option card while control power is applied will cause a hardware fault and can permanently damage the sensitive internal logic bus contacts of both the card and the host inverter. Disconnect all AC line input and auxiliary 24 V DC power sources before hardware service.
- Q: The Link LED turns on, but the PLC reports an I/O communication timeout error. What is the cause?
- A: This indicates physical link connectivity, but the logical POWERLINK node assignment has failed. Verify that the hardware node address configured in the drive parameter parameters matches the exact node number defined in the Automation Studio physical network tree.
- Q: Does the module require an external 24 V DC power input to retain network settings?
- A: No. The card draws all necessary processing power from the internal bus structure of the ACOPOSinverter option bay. All communication configurations are pushed to the device upon system startup by the master PLC controller. Verify specific boot parameters on the official OEM datasheet.
