GE Fanuc IC695CRU320-EN Redundant CPU
GE Fanuc IC695CRU320-EN is a programmable automation controller (PAC) that supports hot standby redundancy, designed and manufactured by GE Fanuc (now possibly merged into Emerson Automation Solutions). The following is a detailed introduction to this redundant CPU:
1. Product Overview
Model: GE Fanuc IC695CRU320-EN
Series: RX3i PACSystems product line
Main functions: As the core processor of the automation control system, it has the function of a logical brain and is used to control different machines, processes, and material handling systems in real time.
2. Technical Specifications
Processing Speed: 1 Gigahertz (GHz)
Memory:
64 megabytes (MB) non-volatile flash memory
64MB battery-backed random access memory (RAM)
Processor: Intel Celeron-M microprocessor
Communication Interface:
Two built-in serial communication ports: one RS-232 port and one RS-485 (or RS-486, slightly different from different sources) port
Supports serial protocols such as SNP, serial I/O, Modbus slave and host
Expandability: Supports local and remote expansion racks, adopts serial backplane design, and is compatible with expansion modules (but not main racks) in the 90-30 series I/O product line
3. Redundancy Features
Hot standby redundancy: This CPU supports hot standby redundancy, that is, users can set up and configure two RX3i CPUs to perform the same function in a given application. When the main CPU fails, the backup CPU can seamlessly take over the control task, thereby minimizing the downtime of time-critical applications.
Switching time: Controller switching is performed in a maximum of 1 logic scan, with a minimum switching time of 3.133 milliseconds.
4. Application environment
Material and protection: Made of hard and durable plastic, it is factory-installed in an open housing and is not suitable for industrial environments with high humidity, dust, debris or water. Therefore, it is recommended to install it in a properly protected enclosure to maintain the environmental parameters specified by the manufacturer.
Operating temperature: It should be maintained between 0 and 60 degrees Celsius (32 to 140 degrees Fahrenheit).
5. Programming and compatibility
Programming environment: Use Proficy Machine Edition, a development environment common to all GE Fanuc controllers.
Installation and connection: The CPU can be installed in the AGFanuc PLC system through the RX3i PCI or 90-30 series serial backplane bus, directly installed into the peripheral component interconnect (PCI) slot, and connected to other modules of the bus through PCI 2.2 or higher.
