INICT03A Communication Interface Module ABB Bailey

INICI03 is a Communication Interface Module in the ABB Bailey control system, mainly used to facilitate information exchange among different functional units within the control system. In the system structure, it plays a more connecting and coordinating role rather than being merely a data acquisition or control execution module.         

The interface behavior and system interaction mode of the INICI03 Communication Interface Module are fixed, which helps engineering projects adopt a unified configuration approach in different devices or batches, thereby reducing the cost of differences between projects.

When expanding the system or making local adjustments, through the INICI03 Communication Interface Module for information exchange, it is possible to avoid directly modifying the core control unit, making the system adjustment scope more controllable and the risks lower.
Improve the efficiency of system problem location.
Due to the clear responsibilities of the interface layer, when the system encounters an abnormal situation, engineers can more quickly distinguish whether it is an interface issue or a control logic issue, thereby reducing the time for fault analysis and handling.

INICI03 Communication Interface Module has compatibility with the original Bailey system structure. In system renovation or upgrade projects, it can continue to be used while retaining the original architecture, reducing the uncertainty brought about by a complete replacement.

The INICT03A Communication Interface Module and INICT12 Computer Transfer Module handle all communication with a host computer. These modules are command-driven through software on the host computer. The module receives a command from the host computer, executes it, and then replies. Its firmware enables the host computer to issue commands for data acquisition, process monitoring, and process control, and to perform system functions such as security, time synchronization, status monitoring, and module configuration.

The INICT03A and INICT12 modules are single printed circuit boards that occupy one slot in the module mounting unit. Their capabilities and computer connection methods differ. The INICT03A module can store up to 30,000 point definitions (depending on point types). The INICT12 module can store up to 10,000 point definitions.

For the INICT03A Communication Interface Module, the circuit board contains microprocessor-based communication circuitry that enables it to directly communicate with its INNIS01 module and to directly communicate with an IMMPI01 module. It communicates with the IMMPI01 module through a ribbon cable connection. The IMMPI01 module handles the actual host computer interface and supports RS-232-C or SCSI serial communication.

For the INICT12 module, the circuit board contains microprocessor-based communication circuitry that enables it to directly communicate with its INNIS01 module and to directly communicate with a host computer using RS-232-C serial communication. The module cable connects to an NTMP01 termination unit. Two RS-232-C ports are located on the termination unit. The NTMP01 jumper configuration determines DTE or DCE operation.
