Functional Description
IC694BEM331 is a Genius I/O Bus controller developed by GE Fanuc. The Genius Bus Controller is a component within the PACSystems RX3i family, designed to interface the PACSystems RX3i with a Genius I/O serial bus. This controller is essential for managing communication across a network of devices, enabling seamless data exchange and fault management.
Features
- Interfaces with a wide range of devices, including Genius blocks, remote drops, VersaMax and Field Control I/O Stations, PLCs with Genius Bus, and the Genius Hand-Held Monitor (HHM). It allows the exchange of up to 128 bytes of data with each connected device, ensuring efficient communication across the network. The controller also facilitates automatic fault reporting from these devices, enabling prompt identification and resolution of issues.
- This controller manages all Genius datagrams and supports the transmission of up to 128 bytes of Global Data with each bus scan. Global Data is automatically broadcasted across the network, keeping all connected devices updated. The controller processes diagnostic messages received from devices, which are then relayed to the CPU for routine monitoring. If programming software is used, any faults detected can be displayed in the fault table for easy troubleshooting.
- The Bus Controller is capable of exchanging up to 128 bytes of data with each device connected to the Genius I/O bus.
- Genius blocks and other devices on the bus automatically communicate faults, alarms, and certain predefined conditions to the Bus Controller. The controller captures and stores any diagnostic messages it receives, which are then automatically accessed by the CPU. Faults can subsequently be displayed in the fault table via the programming software.
- The Bus Controller is compatible with all Genius datagrams. For detailed information on utilizing datagrams, please refer to Chapter 3 of the Genius I/O System and Communications User’s Manual (GEK-90486-1).
- During each bus scan, the Bus Controller can transmit up to 128 bytes of Global Data. This data is broadcast automatically and repetitively by the Genius Bus Controller.
- Additionally, the Bus Controller can receive up to 128 bytes of Global Data during each bus scan from every other Bus Controller present on its bus.
Scalability and Configuration
- Highly scalable, supporting up to eight Genius bus controllers within a single system. Each controller can transfer up to 128 bytes of data, making it suitable for larger installations with numerous devices.
- The controller supports configurable communication rates, including 153.6 Kbaud for standard and extended communication, as well as 76.8 Kbaud and 38.4 Kbaud. The maximum bus length varies with the baud rate:
- 7,800 feet at 4 Kbaud
- 4,500 feet at 76.8 Kbaud
- 3,500 feet at 153.6 Kbaud
- 2,000 feet at 153.6 Kbaud (standard)
- The system can handle up to 32 devices on the bus at most baud rates, with a reduction to 16 devices at 38.4 Kbaud.
LED Indicators and Diagnostic Capabilities
- The front panel features LED indicators that provide real-time feedback on the controller's operating status and the communication bus. These LEDs turn green when the controller is functioning normally, allowing operators to quickly assess system health.
- It is equipped with advanced diagnostic capabilities, enabling it to detect and respond to a variety of errors and faults during PLC system operation. This ensures high system reliability and performance, even in complex industrial environments.
Compatibility
- Series 90-30 PLC: When integrating the RX3i Genius Bus Controller with a Series 90-30 PLC, the CPU model must be one of the following: CPU311K, CPU321K, CPU331L, or any version of CPU313, CPU323, CPU340, CPU341, CPU350, CPU351, CPU352, CPU360, CPU363, or CPU364. Additionally, it is crucial that the CPU firmware is version 5.0 or later to ensure compatibility and full functionality with the Bus Controller.
- Series Six PLC: To facilitate the exchange of global data with an RX3i Genius Bus Controller, a Series Six Bus Controller is required, specifically catalog number CBB902F/903F. The firmware version must be 1.5 or later for effective communication and operation.
- Genius Hand-Held Monitor: While there is no dedicated Hand-Held Monitor (HHM) connector on the Bus Controller module, it is possible for a Hand-Held Monitor to communicate with the Bus Controller when connected to any other device on the Genius bus. To ensure compatibility, the HHM version must be IC660HHM501H (revision 4.5 or later).
- Genius Bus Specifications: The Genius bus utilizes shielded twisted-pair wiring configured in a daisy-chain topology between devices, with termination at both ends to prevent signal loss. The selection of appropriate cabling is vital for the reliable operation of the system. For a comprehensive list of suitable cable types, refer to GEK-90486-1, the Genius I/O System and Communications User’s Manual. Proper adherence to these specifications will enhance the performance and stability of the overall system.
Electrical Specifications
- Features resistors for bus termination, rated at 75 Ohms, 100 Ohms, 120 Ohms, and 150 Ohms, located at both ends of the electric bus cable. It has a Hi-pot isolation rating of 2000 Volts and a transient common mode rejection rating of 1500 Volts, providing robust protection against electrical disturbances.
- The controller operates with a current rating of 300 milliamps at 5 Volts DC, ensuring efficient power usage within the system.
- It is controlled and programmed using Proficy Machine Edition software, providing a user-friendly interface for configuration and monitoring. This software enables detailed system setup, fault management, and data exchange control.
