NI PCI-5565PIORC Reflective memory node card

The NI PCI-5565PIORC Reflective memory node card is a real-time fiber optic network product based on the PCI interface or PCI Express interface, which provides high-speed, low-latency, deterministic data sharing capability. The following is a detailed analysis of the product:

1. Basic information

Model: PCI-5565PIORC (Some models may include PCI-5565-PIORC, indicating PCI Express version)

Manufacturer: Usually associated with NI (National Instruments), but please note that specific models may be manufactured or branded by different manufacturers

Type: reflective memory node card

Second, product characteristics

High-speed data sharing:

The PCI-5565PIORC allows data to be shared between up to 256 independent systems (nodes) at rates of up to 170Mbyte/s.

Each reflective memory board can be configured with 128MB or 256MB on-board SDRAM, providing fast read access time to stored data.

Low latency and certainty:

Data transfer is software-transparent and requires no I/O overhead, reducing latency and improving system certainty.

Data transfer between nodes is carried out automatically by the onboard circuit without CPU involvement.

Flexibility and compatibility:

Data can be shared in real time across computers, workstations, PLCS and other embedded controllers with different architectures and different operating systems.

Supports multiple operating systems, such as Windows, Linux, and VxWorks.

High reliability and redundancy:

Optional redundant transmission mode can suppress additional errors and improve system reliability and stability.

Any node on the network can generate an interrupt in any other node on the network or in all network nodes with a single command.

Easy to use fiber optic network:

Support for 33MHZ 64-BIT/32-BIT PCI bus compatibility, as well as PCI Express 2.5GHz signaling (for PCI Express versions).

Fiber optic network transmission rates range from 43MByte/s (4-byte packets) to 170MByte/s (64-byte packets).

Support multi-mode fiber up to 300 meters, single-mode fiber up to 10 kilometers of transmission distance.

3. Application scenarios

The PCI-5565PIORC reflective memory node card is widely used in applications requiring high-speed, low-latency, deterministic data sharing, such as real-time simulation systems, distributed control systems, industrial automation and other fields.
