Introduction
Considering the advancement of the industrial machine automa-
tion field, designers not only use centralized control systems but
also need a distributed solution to develop more complex machine
applications. Distributed solutions provide many benefits such as
lower maintenance, reduced wiring and a vast number of modules
that are easy to integrate. Motionnet and HSL technologies are
innovative distributed motion and I/O technology that enable time-
deterministic scanning of thousands of I/O points in milliseconds
using master-slave architecture. The Motionnet bus further
improves distributed motion control capability by providing control
axes up to 256 axes and minimal command execution time for sin-
gle axis control.
The PCI-7856 is a PCI interface card which 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 mater-slave architec-
ture. Commercial Ethernet cables with RJ45 connector are used
for simplified setup of the HSL slaves modules as close as possi-
ble to sensor devices which results in a dramatic reduction of wir-
ing. System integrators can benefit from HSL network because it
integrates discrete I/O and analog I/O modules. This local network
features rapid response, 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 which provides distributed motion axis control
of up to 256 axes for any servo / stepper motor controlled using
mater-slave architecture. This not only provides general purpose
4-axes motion control, but also allows specific 64 of single axis
motion control module to be scanned in millisecond-level in real
time.
