Engineers will appreciate the distributed architecture enabled by the IMFBS01. This module operates as a slave on the field bus network. Consequently, users can deploy I/O modules up to 500 meters away from the main controller.

Furthermore, the module supports up to 64 I/O modules per bus segment. This capacity allows extensive I/O expansion without requiring additional controller slots. The IMFBS01 manages all communication between remote field devices and the system master.

Interface and Communication Details

The IMFBS01 features a dedicated field bus interface for remote I/O connectivity. This interface operates at 1.5 Mbps data rate for efficient data exchange. The module uses standard twisted-pair cabling for simple installation.

The unit communicates with the system master through the INFI 90 Module Bus. It translates between the two network protocols seamlessly. For reference, other Bailey INFI 90 field bus components share this same communication architecture.

Memory and Data Management

The IMFBS01 includes 64 kilobytes of RAM for real-time data buffering. This memory holds current I/O values during communication cycles. An additional 128 kilobytes of flash memory stores configuration parameters and firmware.

The module handles all polling and data acquisition tasks independently. This design reduces communication overhead on the main processor. Engineers can rely on this performance for reliable remote I/O operation.

System Integration and Diagnostics

You can install this slave module in any INFI 90 rack system. The IMFBS01 connects to field bus segments through standard terminal connections. Diagnostic LEDs indicate power, communication activity, and bus status. These features simplify network troubleshooting and ensure reliable operation.
