Motion Control

Common Motion API

Introduction

Architecture and Features of Common Motion API

Advantech’s New Generation Motion Control Software

System integrators often encounter difﬁculties when an engineer may not be familiar with the different syntaxes during the integration of various motion control cards. And what

bother them the most is that when the system has to be upgraded, the problems often occur with rewriting the program as well as increasing the development time. To reduce these

difﬁculties, Advantech has introduced a uniﬁed interface - Common Motion API- which provides a single syntax and interface, regardless of the types of motion control card the

integrator chooses to use. The design can proceed under a single syntax interface to save development time and speed up the time to market. The ACM (Advantech Common Motion)

architecture deﬁnes a single interface which consists of three types of operation objects, including Device, Axis and Group and each object has its own Property, Method and State.

Features of Common Motion API

 Provides complete debugging tool utility

- Hardware wiring testing

- Software functional testing

- Condition & status monitoring

 Provides the dedicated APIs for different applications

 Simpliﬁes API calls process

 Improves the integration

 Supports scalable hardware

- Supports the existing hardware and future hardware development, such

as PCI-1245/45E/45L/65/85/85E series

Through the above advantages and the lower learning threshold, integrators

can signiﬁcantly reduce development time and follow-up maintenance work!
