The GE Fanuc Emerson IC694BEM331 is a Genius bus controller that offers communication of thirty-two devices with the PACSystems RX3i system. This unit reserves in a backplane one single slot. The device can be employed in many standard applications and is compatible with many devices and PLCs. This controller has two LED indicators on the faceplate to show the current status. The IC694BEM331 bus controller can be employed with Genius blocks and remote drops. This controller can be connected with a Genius HHM. The unit can be employed also with Field Control I/O stations and VersaMax. The IC694BEM331 supports GBC communication and datagrams. The bus controller draws a current of 300 milliamperes at a bus voltage of 5 volts DC.

This unit offers many configurable baud rates such as 38.4 kilobaud, 76.8 kilobaud, and 153.5 kilobaud with a maximum bus distance of 2377.44 meters (7800 feet). The IC694BEM331 supports many values of termination resistors at both ends of the bus cable that are: 75 ohms, 100 ohms, 120 ohms, and 150 ohms. This controller supports either shielded twisted pair cable or daisy-chain connections. The controller employs the backplane optical isolation offered by optocouplers to provide electrical isolation of 2000 volts AC and 1500 volts AC transient common-mode rejection. This unit supports a non-condensing relative humidity range from 5 percent to 95 percent and a vibration frequency range from 10 hertz to 500 hertz. The IC694BEM331 weighs approximately 360 grams (0.8 pounds) while shipping and operates at 0 degrees to 60 degrees Celsius (32 degrees to 140 degrees Fahrenheit) for industrial applications.

The IC694BEM331 controller is made by GE Fanuc Automation Genius I/O Bus controller that is part of the RX3i PACSystems product line. It is planned to work in unison with RX3i PACSystems controllers and serial Bus I/O. This controller pairs well with and operates in conjunction with a variety of blocks, remote drops, controllers, portable monitoring devices, and I/O stations. The IC694BEM331 controller supports the simultaneous exchange of up to 128 data bytes across the I/O bus. Two LED indicators that indicate the controller's operating status and communication bus status are on the front of this Genius, I/O Bus controller. When the module is in normal operation, these two LED indications glow green. These LED indicators reflect the module's operational and communication status. During regular functioning, the OK LED is automatically enabled. This LED is switched off during diagnostics and power-up. The COM LED indicates the state of the Genius Bus's communication exchange. When the system is working properly, the COM LED illuminates. When an intermittent bus issue occurs, the COM LED blinks and then turns fully out when the Genius Bus fails. Additionally, the COM LED is not illuminated when the CPU does not receive qualifying data from the IC694BEM331 Bus controller. It offers a variety of customizable data rates; for example, it ships with a rate of 153.5 Kbaud for standard and enhanced communication. Additionally, this device supports transmission speeds of about 76.8 Kbaud and 38.4 Kbaud.
 The RX3i PACSystems IC694BEM331 Genius I/O Bus controller by GE Fanuc terminates the bus with resistors configured at 75 Ohms, 100 Ohms, 120 Ohms, and 150 Ohms on both ends of the electric bus wire. This GE Bus controller has a 2000 Volts Hi-pot isolation rating and a 1500 Volts transient common-mode cancellation rating. Proficy Machine Edition programming software is used to manage the GE Fanuc IC694BEM331 Bus controller unit. It has a rated current of 300 milliamperes and a voltage rating of 5 volts direct current. Additionally, this device has enhanced diagnostic capabilities since it can identify a variety of problems and malfunctions while the PLC system is operating.
