Product Description


The GE Fanuc IC694BEM331 Genius Bus Controller interfaces a PACSystems RX3i and a Genius I/O serial bus. In addition to the Bus Controller, the bus will also serve: Genius blocks, remote drops, VersaMax and Field Control I/O Stations, PLCs with Genius Bus, Genius Hand-Held Monitor (HHM), and numerous hosts. Featuring 128 bytes exchange with each device on the Genius I/O bus, the Genius blocks and other devices report faults in an automatic fashion, including alarms and certain other previously defined issues to the bus controller. The bus controller then manages any diagnostic messages it receives, which are then read by the CPU routinely. Faults can then be displayed in the fault table if the programming software is employed.

The IC694BEM331 maintains all Genius datagrams and can send up to 128 bytes of Global Data with each bus review. Global data is data that is spontaneously and mechanically broadcast. Up to eight Genius bus controllers can be incorporated in the system with each transferring up to 128 bytes.

LEDs are found on the front of the controller to specify operating status. With advanced diagnostic capabilities, the daisy chained bus cable uses a single twisted pair plus shield or Twinax. However, fiber optic cable and modems can also be used. The largest length of the bus is 7800 feet at 4Kbaud, 4500 feet at 76.8 Kbaud, 3500 feet at 153.6 Kbaud, and 2000 feet at 153.6 Kbaud standard. The highest number of devices for this unit is 32 at all baud rates except the 38.4 Kbaud or 16 devices at 38.4 Kbaud. The controller is well-suited with multiple series and can trade global data with an RX3i Genius bus controller with firmware version 1.5 or higher. The user should know that no handheld monitor connector is available on the module, but a handheld monitor can interconnect with the controller.

The IC694BEM331 controller is a Genius I/O Bus controller manufactured by GE Fanuc Automation as a member of the RX3i PACSystems product line. It is designed to interface seamlessly with the RX3i PACSystems controllers as well as the serial Bus I/O. This controller is well matched with and works with various blocks, remote drops, controllers, handheld monitoring devices, and I/O stations. The IC694BEM331 controller allows for exchange of up to 128 data bytes on the I/O bus at one time. There are 2 LED indicators on the front of this Genius I/O Bus controller to show the status of operation and communication bus status. These 2 LED indicators turn green when the module is in regular operation. It supports various data rates which are configurable, for instance, it comes with a rate of 153.5 Kbaud for standard and extended communication. This unit also comes with possible communication rates of about 76.8 Kbaud and 38.4 Kbaud.

The GE Fanuc RX3i PACSystems IC694BEM331 Genius I/O Bus controller has resistors rated at 75 Ohms, 100 Ohms, 120 Ohms, and 150 Ohms for the bus termination and the resistors are found on both ends of the electric bus cable. This GE Bus controller features a Hi-pot isolation rating of 2000 Volts, with a transient common mode rejection rating of 1500 Volts. The GE Fanuc IC694BEM331 Bus controller unit is controlled through the Proficy Machine Edition programming software. It has 300 milliamps of rated current with a voltage rating of 5 Volts DC. This unit also has improved diagnostic abilities and it can detect various errors and faults while the PLC system is in operation.
