User-friendly route to distibuted motion control

An Agile Systems product story
Edited by the Engineeringtalk editorial team Dec 1, 2003

Command Interface is a new language for distributed motion control that opens up the communication protocol so packets can be created independently of library or host platform.

Agile Systems has released the next generation of network support for its line of distributed motion controllers and drive products.

This proprietary network language, entitled Command Interface, opens up the communication protocol so packets can be created independently of library or host platform in an easy user-friendly format.

Command Interface consists of a rich instruction set for complete control and flexibility for all motion control needs.

The release of Command Interface helps customers reduce servosystem costs and increase portability while taking advantage of new powerful features.

Opening the communication protocol means a software license is no longer necessary to communicate with Agile Systems controllers.

An ANSI C library is available that provides portability across Unix, VxWorks, QNX, Windows, RTOS or any host that supplies an ANSI C compiler.

Based on a query-response model, Command Interface specifies an easy user-friendly approach to commanding and interacting with Agile's family of distributed motion controllers.

Communication with Agile's patented DigitalPower platform technology has never been easier.

Key features of the Command Interface specification include: packet standardisation across Agile's complete line of motion control products; increased portability for system developers; a query-response model with responses being generated within 100us; 22 commands or register based instruction set; six return packet possibilities; instruction set for specifying motion, status of inputs, outputs, registers and motion status; support for commands for PTP, PT, PVT, pulse and direction; cyclic redundancy check protection for detecting transmission errors; and an ANSI-C library available for packet generation.
