PCI-7020F-00A1E Application Field and Working Principle

PCI-7020F-00A1E is a compact 4-channel isolated CAN bus module developed by ADLINK for industrial application and vehicle control. This product adopts a PCI bus platform. And it conforms to the PC104+ expansion bus standard and PCI v2.2 agreement. By utilizing the high isolation voltage of 2000V, PCI-7020F-00A1E makes the system reliable and free from external electrical noise interference.

This product is applicable to the fieldbus of industrial automation and control and inter-vehicle communication applications, especially when the operational environment requires heavy vibration, high reliability, or high isolation. For example, it can be used as a bridge between a separate CAN bus network and the PC, with Linux, Windows XP or Win CE 6.0 as the operating system.

Application Fields

PCI-7020F-00A1E can be used in various industrial motion control projects, such as factory automation, machine control, process control, medical devices, vehicle and motorcycle bridge connection, etc. For instance, it can be used to drive motor and tamper detection in medical robots. It can also be used in fuel supply control, instrumentation control, automated accurate dispensing, flow control, motion control acceleration, etc.

Working Principle

PCI-7020F-00A1E adopts a CAN bus protocol stack, which is suitable for industrial control environments and can provide higher level solutions. It supports both standard CAN 2.0A protocol and extended CAN 2.0B protocol, with a communication speed up to 1Mb/s.It also supports 8 priorities and error voting algorithms, and can strengthen the network stability. The adjustment and programming of the module is very simple because it can be done online.

The module contains point-to-point, point-to-multipoint, multidrop configurations and voting mechanisms for applications that require extremely reliable message transmission. This solution also provides redundant message transmission that can verify the data and repeat the transmission if it detects an error. It also provides bit-level mask configuration control, allowing the nodes to be assigned a filter to ensure uninterrupted communication.
