The IC695CRU320 is a redundant processor in the PACSystems RX3i product family. The processor is manufactured by GE Fanuc/Emerson automation and is classified as a Programmable Automation controller (PAC).
The IC695CRU320 is especially used in redundant or hot standby configurations. With this controller configuration, availability is significantly improved. Two (2) controller racks with similar configuration functions as the primary (active) and secondary (standby) racks. When a single rack fails, mainly due to an error detected by the IC695CRU320 or an error by the IC695CRU320 processor itself, the responsibility of the active controller is automatically transferred to the secondary (standby) controller. The auxiliary rack becomes the host rack, and the faulty rack is moved to the auxiliary rack. In addition, it can be switched manually.
Controller switching is performed in a maximum of one logical scan with a minimum switching time of 3.133 ms. It supports up to IC695RMX128/228 synchronous links and is capable of transmitting up to 2MB of data. The controller uses a Celeron M processor with 1GHz processing speed and 64MB of user memory, making it ideal for large, complex applications with higher criticality. In addition, up to 512 blocks can be saved to this processor, with each block size up to 128 KB.
The IC695CRU320 processor is mounted on the RX3i backplane directly into the Peripheral Component Interconnect (PCI) slot. Other modules are also connected to the bus via PCI version 2.2 or later. This PCI slot enables fast transfer and sharing of data within the backplane. The IC695CRU320 also supports the 90-30 series I/O modules for phased migration.
The GE Fanuc IC695CRU320 CPU has current requirements of 1 amp at 3.3 volts DC and 1.2 amps at 5 volts DC. Two integrated serial ports are provided on the module to support RS-232 and RS-485 communication respectively. A maximum of 512 blocks can be configured, each of which supports a maximum of 128 KB. Flash memory has a durability rating of at least 100,000 write/erase cycles. The minimum switchover time is 3.133 ms and the maximum switchover time is 1 logical scan. The maximum amount of data that can be transferred at one time is 2 MB. The IC695CRU320 CPU supports up to two IC695RMX128/228 synchronous links for redundancy. The programming of the IC695CRU320 CPU can be done in ladder diagram, C language and function block diagram language. Ethernet communication is supported through the rack-mounted Ethernet communication module.
