What is the difference between centralized and distributed motion control ?
Complete Application-Ready Platforms for the General Motion Control Market
Advantech offers application-ready platforms that range from industrial workstations and industrial-grade CPUs, to motion control, encoder input and isolated I/O cards for
general motion control (GMC) application such as SMT/PCB, semicondutor and LCD manufacturing machines. As machine automation develops, high speed, effective distance
transmissions, and convenient wiring become increasingly important for system integrators. Advantech Distributed Motion Control (AMONet) is a series of products with innovative
architecture that is designed for versatile industrial automation application, and are especially suitable for distributed motion control requirements.
Machine control system architectures generally fall into two categories - centralized or distributed.
In a centralized system, all control loops including logic, trajectory generation, and PID control, are
executed on a single processor on a programmable automation controller (PAC). In a distributed
system, the trajectory generation and logic control executes in the central processor, but the
PID control loop is executed in the intelligent slave module. A distributed approach gives more
processing power, while it reduces overall wiring cost and system complexity.
The Distributed Motion Control Products are categorized in two groups - Master Cards and Slave
Modules. Communication between master and slave is based on a custom-engineered technology
based on RS-485, which saves wires, transmits over long distances at high speeds, and have
time-deterministic features.
The communication interface between master and host PC is based on memory mapping. Various
functions can be chosen on the slave modules, and the industrial DIN-rail mountable design makes
it easy to distribute them in the field. The master card collects information from slave modules and
publishes the data to its host PC, and vice versa.
