FUNCTIONAL DESCRIPTION:

IC670GBI002 is a Field Control Genius Bus Interface Unit I/O Module manufactured and designed by General Electric as part of the Mark I & II Series used in GE Speedtronic Turbine Control Systems. Field Control Genius Bus Interface Unit I/O Module to a host PLC or computer via a Genius bus. It can exchange up to 128 bytes of input data and 128 bytes of output data with the host, each Genius bus scan. It can also handle Genius datagram communications. The intelligent processing capabilities of the Genius Bus Interface Unit allow the configuration of features such as fault reporting, selectable input and output defaults, analog scaling, and analog range selection for the modules in the station. In addition, the Genius Bus Interface Unit performs diagnostic checks on itself and its I/O modules, and relays diagnostic information to the host (if configured for fault reporting) and to a Hand-held Monitor. The Genius Bus Interface Unit can be used on a bus controlled by redundant CPUs or Bus Controllers. It can also be used on a dual bus. The Bus Interface Unit mounts on a Bus Interface Unit Terminal Block. It can be removed and replaced if necessary without removing the wiring or reconfiguring the I/O station.

BUS INTERFACE UNIT TERMINAL BLOCK:

The Bus Interface Unit Terminal Block, which is included with the BIU, has connections for power wiring and single or dual communications cables. It has built-in bus-switching circuitry, allowing the Bus Interface Unit to be used on a dual (redundant) Genius bus (no external Bus Switching Module is needed). The Bus Interface Unit Terminal Block stores the configuration parameters selected for the station. Field Control I/O Modules are available in many types to suit a wide range of application needs. Modules can be installed and removed without disturbing field wiring. One or two I/O modules may be mounted on an I/O Terminal Block.

FIELD CONTROL IN A GENIUS SYSTEMS:

The Genius bus is an industrially-hardened Local Area Network (LAN). It passes I/O (control) data and background information (datagrams) between the Bus Interface Unit and a Genius bus controller. A Genius bus can support up to 32 devices. Each Bus Interface Unit station counts as one device on the bus, regardless of the number or type of modules present in the station. Other devices on the same bus can be Field Control stations, remote drops, I/O blocks, Bus Controllers, and Hand-held Monitors. Typical buses reserve one location for a Bus Controller and one for a Hand-held Monitor, leaving 30 for additional devices. The illustration below shows a Series 90-70 PLC connected to a Genius bus with I/O blocks and two Field Control stations.

FREQUENTLY ASKED QUESTIONS:

What is a Bus Interface Unit (BUI)?

A Bus Interface Unit (BUI) is a device used to interface with a host PLC or computer via a Genius bus, enabling the exchange of input and output data, diagnostic checks, and fault reporting between the system and the bus.

What is the voltage range for a typical Bus Interface Unit (BUI)?

A typical BUI operates within a voltage range of 90 to 135 Volts AC and 105 to 150 Volts DC, with a nominal supply voltage of 24 VDC.

What types of diagnostics can a BUI perform?

A Bus Interface Unit is typically equipped with intelligent processing to perform self-diagnostics on itself and its associated I/O modules. Diagnostic information can be communicated to the host or a Hand-held Monitor (if configured for fault reporting).

What is the power consumption of a typical BUI?

A Bus Interface Unit typically consumes around 16.8 watts of power during operation. Power consumption may vary based on voltage (e.g., 48 Volt-Amps at 115 Volts AC).
