The PCI-7856 is a PCI interface card that offers two ports for Motionnet and HSL systems for distributed motion and I/O in machine automation applications.

HSL technology allows thousands of I/O points to be scanned at the millisecond level in real-time by using master-slave architecture. Commercial Ethernet cables with RJ45 connectors are used for the simplified setup of the HSL slaves modules as close as possible to sensor devices which results in a dramatic reduction of wiring. System integrators can benefit from the HSL network because it integrates discrete I/O and analog I/O modules. This local network features rapid response and real-time scanning.

A Motionnet system (referred to as “MNET”) is a distributed motion solution for machine systems. MNET is an innovative distributed motion technology that provides distributed motion axis control of up to 256 axes for any servo/stepper motor controlled using master-slave architecture. This not only provides general-purpose 4-axes motion control but also allows specific 64 of the single-axis motion control module to be scanned at millisecond-level in real-time.

Motionnet and HSL features:

*Flexible, comprehensive, extendable distributed motion and I/O solution based on PC architecture or embedded platform

*Convenient wiring for remote distributed motion & I/O modules, including multiple-axis motion control module, single-axis motion control module, discrete I/Os, and analog I/Os

*Space-saving, reduced wiring, and easier maintenance for cost-saving

*Time-deterministic, fast scanning with hundreds of discrete I/O points (up to 2,016 points)

*Real-time and fast scanning to realize high-speed and high-response motion control up to 256 axes support.
