IC695CPU320-HS RX3i Series CPU – GE

Description

Product Description
IC695CPU320 is the central processing unit of the GE Fanuc PACSystems RX3i series. IC695CPU320 has an Intel Celeron-M microprocessor with a rated frequency of 1 GHz, with 64 MB of user (random access) memory and 64 MB of flash memory. The RX3i CPU is programmed and configured to control machines, processes, and material handling systems in real-time.
The chassis of IC695CPU320 is equipped with a pair of independent serial ports. Both serial ports occupy one slot on the system base. The CPU supports SNP, serial I/O, and Modbus Slave serial protocols. In addition, IC695CPU320 has a dual backplane design, and the bus supports RX3i PCI and 90-30 serial bus. Like other CPUs in the Rx3i product series, IC695CPU320 provides automatic error checking and correction.
IC695CPU320 uses Proficy Machine Edition, which is a common development environment for all GE Fanuc controllers. The Proficy Machine Edition is designed specifically for creating, running, and diagnosing operator interfaces, motion, and control applications.

Many examples of faults indicate that in order to reduce the probability of faults in the DCS system, it is necessary to carry out comprehensive work from DCS selection design to operation, start and stop maintenance.
1. Selection, design and debugging of DCS
1.1 The configuration of the system and controller should focus on reliability and load rate (including redundancy) indicators. The communication load rate must be controlled within a reasonable range, and the load rate of the controller should be as balanced as possible to avoid the occurrence of “high load” problems.
1.2 The allocation of system control logic should not be overly concentrated on a certain controller, and the main controller should adopt redundant configuration.
1.3 The power supply design must be reasonable and reliable. Pay attention to the load rate of power supply design and the redundant configuration of power supply to ensure two independent power sources.
1.4 Pay attention to the reliability of DCS system interfaces, and pay attention to the interface methods and redundancy of important interfaces.
1.5 The grounding of the DCS system shall be carried out according to the manufacturer’s requirements to avoid grounding issues causing large-scale system failures. Attention should be paid to considering anti-interference measures of the system, and I/O channels should emphasize isolation measures. Pay attention to cable quality and shielding, and use computer specific communication shielded cables for important signals and controls.
1.6 According to the operating characteristics of the equipment and the requirements for handling emergency faults of the unit under various working conditions, configure an operator station and backup manual operation device. The emergency shutdown button configuration should adopt a separate operating circuit from DCS.
1.7 For the protection system, use the multiple signal acquisition method. Reasonably use the blocking conditions to enable the signal circuit to have logical judgment ability.
During the debugging period, all logic, circuits, and working conditions shall be tested according to the debugging outline and methods to ensure that all parameter settings are correct and reasonable.

2. DCS operation, start stop maintenance
2.1 Prepare for maintenance
The maintenance of the DCS system requires the following preparations:
(1) Maintenance personnel should be familiar with the structure and functional composition of the DCS system, understand the hardware knowledge of the system equipment, and proficiently master the DCS configuration software.
(2) System backup: including operating system, control system software, and logical configuration to ensure data integrity and up-to-date. Priority should be given to using optical disks, and using mobile hard drives, USB drives, etc. to ensure dedicated use of dedicated disks.
(3) Hardware reserve: Make an appropriate backup of vulnerable and short life components and key components, ensuring that there is no less than one spare part for each type of card and module, and store it according to the manufacturer’s requirements. If conditions permit, the spare parts should be verified.
(4) Organize the scope and schedule of product after-sales service, and form a technical support communication list for DCS manufacturers and design and debugging units.
