Configured for serial communication transfer and node-to-node data routing in ABB Infi 90 networks, the ABB INIIT01 (INIIT01 Infinet to Infinet Transfer Module) provides direct electrical execution. The module transfers communication packets between Infi-Net segments through dual full-duplex EIA RS-232-C serial interfaces while maintaining deterministic loop communication timing across distributed system nodes.

Module Revision Information

The INIIT01 is supplied as a dedicated transfer communication module for ABB Bailey Infi 90 systems. Available technical data does not define configurable suffix matrices or optional hardware subvariants for this module type.

Hardware Specifications

Deterministic Communication Architecture

The INIIT01 module exchanges communication frames between interconnected Infi-Net loops using high-speed deterministic backplane synchronization. Internal transfer logic coordinates message routing between serial communication interfaces and distributed network nodes.

Backplane communication timing is dependent on connector seating stability and electrical continuity across rack interfaces. Shield grounding consistency between cabinet sections assists in limiting communication retries caused by transient voltage differentials.

The module supports scalable network density through loop segmentation and distributed node assignment structures. Communication throughput is influenced by configured baud rate, loop loading, and serial interface utilization.

Technical Questions

Q: What serial communication standard is supported by the INIIT01?
A: The module supports dual full duplex EIA RS-232-C serial communication interfaces.

Q: Can the baud rate be adjusted by the user?
A: Yes. User-selectable communication rates from 75 baud to 19,200 baud are supported through module configuration.

Q: What network size can the module support?
A: The documented system capability supports up to 62,500 system nodes with 250 nodes per communication loop.

Q: Does the module perform protocol conversion between external networks?
A: The available technical data identifies the INIIT01 as an Infi-Net to Infi-Net transfer module for internal ABB communication routing.

Q: What installation condition most affects communication stability?
A: Improper grounding references, loose connector engagement, and routing serial communication wiring adjacent to high-current AC conductors may introduce communication transfer errors.

Installation and Wiring Practices

• Install the module with rack power removed whenever maintenance procedures permit.

• Verify grounding continuity between communication cabinets before energizing the network loop.

• Route RS-232 communication wiring separately from motor control and AC feeder circuits.

• Maintain proper connector insertion pressure during backplane installation.

• Use anti-static handling procedures during servicing and transportation.

• Inspect edge connectors for contamination or contact deformation before installation.

• Maintain cabinet airflow conditions within specified ambient operating limits.
