GDD471A001 ABB 控制卡模块
首先，要明确一点，无论是PLC，还是运动控制器、运动控制卡，它们的本质都是一种控制器，主要负责自动化系统中运动轴的控制，同时也支持输入输出信号的控制。从区别来看，主要有以下几点:
1、GDD471A001 ABB 控制卡模块PLC的专长在于逻辑10控制，实现一些复杂的逻辑控制都很易。对于运动控制，一般低端的PLC主要是通过高速输出点来进行脉冲控制，中高端PLC一般会通过总线的方式来进行控制，常用的总线包括Profinet、EtherCAT、CC-Link等.
2、GDD471A001 ABB 控制卡模块运动控卡通过PCI插槽将控制卡插在PC的主机上，也可以通过以大网连接到PC主机上;利用高级编程语言C++、C#、VB、http:/VBNETlabview等编程语言进行开发;编程中使用运动控制卡厂商提供的控制卡AP接口函数，来实现对控制卡资源的使用;运动控制卡也分为脉冲型和总线型，一般总线型要比脉冲型稍贵一些。

3、GDD471A001 ABB 控制卡模块PLC具有工作可靠，编程简单等优点，但其运动控制功能相对简单，PLC的应用过程中主要通过PLC+HMI，这就导致可视化界面受到了一定的限制，因此现在基于PLC的上位机应用也越来越广泛;
运动控制卡可以利用PC强大的功能，比CAD功能、机器视觉功能、软件高级编程等，利用FPGA+DSP / ARM + DSP芯片的功能实现高精度的运动控制 (多轴直线、圆弧插补等，运动跟随，PWM控制等)。
5、运动控制器和运动控制卡的算法几乎一样，它们之间的主要区别在于运动控制卡需要依赖于P编程，而运动控制器可以直接写程序并下载，这样就可以脱机运行
6、随着机器视觉的广泛应用，运动控制与机器视觉得到了良好的结合，相比之下，视觉项目采用运动控制卡能够节约很大的硬件成本，总而言之，PLC相对来说更偏向于逻辑控制，而弱化于运动控制，而运动控制卡、运动控制器更偏向于运动控制，而弱化于逻辑控制，同时，运动控制卡和运动控制器对开发人员的门槛也要相对高一些，因此大家可以根据自己的实际情况，选择合适的解决方案。

GDD471A001 ABB control card module
First of all, to be clear, whether it is PLC, or motion controller, motion control card, their essence is a controller, mainly responsible for the control of the motion axis in the automation system, but also support the control of input and output signals. From the perspective of difference, there are mainly the following points:
1, GDD471A001 ABB control card module PLC expertise lies in logic 10 control, to achieve some complex logic control is very easy. For motion control, the general low-end PLC is mainly through the high-speed output point to pulse control, and the high-end PLC is generally controlled by the bus, the commonly used bus includes Profinet, EtherCAT, CC-Link and so on.
2, GDD471A001 ABB control card module Motion control card through the PCI slot the control card is inserted in the PC host, can also be connected to the PC host through a large network; Using high-level programming languages C++, C#, VB, http:/VBNETlabview and other programming languages for development; The control card AP interface function provided by the motion control card manufacturer is used in programming to realize the use of control card resources. Motion control cards are also divided into pulse type and bus type, and the general bus type is slightly more expensive than the pulse type.
3, GDD471A001 ABB control card module PLC has the advantages of reliable work, simple programming, but its motion control function is relatively simple, PLC application process mainly through PLC+HMI, which leads to a certain limitation of the visual interface, so now based on PLC PC applications are more and more widely;
Motion control card can use the powerful functions of PC, than CAD function, machine vision function, software advanced programming, etc., the use of FPGA+DSP/ARM +DSP chip functions to achieve high-precision motion control (multi-axis straight line, arc interpolation, motion following, PWM control, etc.).
5, the motion controller and the motion control card algorithm is almost the same, the main difference between them is that the motion control card needs to rely on P programming, and the motion controller can directly write programs and download, so that you can run offline
6, with the wide application of machine vision, motion control and machine vision have been a good combination, in contrast, visual projects using motion control card can save a lot of hardware costs, all in all, PLC is relatively more inclined to logic control, and weakened in motion control, and motion control card, motion controller is more inclined to motion control, and weakened in logic control, At the same time, the threshold of motion control cards and motion controllers for developers is also relatively high, so we can choose the right solution according to our actual situation.
