The ABB INIIT12 serves as the primary INIIT12 Infi-Net to Infi-Net Transfer Module utilized to execute high-speed data unidirectional or bidirectional bridging across Infi 90 platforms. It establishes the physical and protocol interface required to route data packets between independent INFI-NET communication rings via integrated serial ports.

Hardware Specifications

Backplane Bus Communication Velocity and System Firmware Integration

The INIIT12 operates in strict compliance with the deterministic backplane bus communication velocity baselines defined for the Infi 90 module mounting unit. Data processing between separated processing rings is managed via local memory blocks, utilizing the 256 kbytes NVRAM segment to retain cross-ring node addresses and configuration mapping parameters during power disruptions. Firmware flash compatibility must be validated across all participating system network components to ensure that data packet routing across the dual RS-232-C channels avoids synchronization lag and transmission time-outs.

Frequently Asked Questions

Q: What are the specific power supply requirements for the INIIT12 module?

A: The module demands a steady current load of 2 A at +5 VDC from the shared chassis backplane. Power distribution calculations must budget exactly 10 W for this slot to maintain overall voltage regulation.

Q: How is the configuration mapping retained when the rack loses power?

A: Node configurations and ring mapping parameters are stored within the 256 kbytes of onboard non-volatile RAM (NVRAM), bypassing the need for continuous backplane battery backup power.

Q: Can this module card be extracted or replaced while the backplane bus is fully energized?

A: No. The INIIT12 does not possess hot-swap capability. Removing or inserting the card while live can induce electrical transients that disrupt active data packets on the backplane or corrupt the onboard memory contents.

Field Installation Guidelines

• Isolate all incoming power sources connected to the module rack assembly before inserting or extracting the hardware card.

• Align the upper and lower circuit board edges carefully within the module guide tracks to guarantee full insertion into the backplane connector.

• Route all asynchronous RS-232-C serial cables in separate conduits isolated from high-current AC power cables or inductive motor control loads.

• Clamp the braided shields of all external serial communication cables directly to the central copper earth ground bus bar inside the enclosure.
