SMC总线技术简介（中英文对照）

What is Serial Networking technology?
什么是串行网络系统？

Serial Network systems use serial transmission to enable controllers (a PC or PLC) to control remoy located process equipment. Programmed commands are generated by the controller and are sent through a two-wire (twisted pair cable) connection to a remote input/output (remote I/O) block. These inputs and outputs are then
connected to devices such as pneumatic solenoid valves, sensors, or instrumentation of some type.

串行网络系统使用的是串行传输，从而使控制器（PC或者PLC）远程控制本地生产设备。 编程指令由控制器产生，并通过双线（双绞电缆）与远程输入输出（远程I/O）模块连接。 这些输入输出模块与诸如电磁阀、传感器、某种类型的仪器等设备相连。

So why does Serial Networking have such an impact on your profitability? To truly appreciate Serial Interface technology, you should understand the difference between a serial and a conventional control system.

那么，为什么串行网络系统会如此影响你的效益？实际上还得益于串行接口技术，你应该明白串行系统和传统控制系统之间的差别。

In a conventional control system, I/O cards are located inside the PLC chassis. All wire connections from actuators, limit switches, proximity switches, regulators, etc. have to be fed back to the PLC. Big deal? Well, depending upon the complexity of the system, the number of wires can easily be in the thousands. Try troubleshooting that system with any speed or efficiency.

在传统的控制系统中，I/O卡位于PLC机箱内。所有连接执行器、限位开关、接近开关、监视器等设备的电线都必须反馈到PLC中。这也没有什么大不了的？嗯，这取决于系统的复杂性以及数以千计的电线。要排除此系统中的故障要耗费巨大的时间和精力。

In a Serial Network system, all the I/O cards and the enormous bundle of wires are replaced with a few cables, a scanner, a Serial Interface unit, and input device. Troubleshooting is quick because of the diagnostic apabilities that are inherent to Serial Network systems.

而在串行网络系统中，所有的I/O卡和数量庞大的电线被一根电缆、一个扫描器和一个串行接口单元及输入设备取代。故障可以快速排除，因为在串行网络系统中内置了诊断功能。

System integrators and engineers have the freedom needed to design world-class control systems thanks to the SMC family of Serial Network (otherwise known as Serial Interface) products.

得益于SMC的串行网络（又称串行接口）产品，系统集成商和工程师可以根据需要自由设计*的系统。

EX250
This advanced system not only has 32 sensor input points (in addition to 32 solenoid valve output points), but it is also IP67 rated for those applications in adverse conditions. Series EX250’s self-diagnostic functions help you quickly identify problems that could have otherwise caused major downtime.

这种先进的系统不仅具有32个传感器输入点（以及32电磁阀输出点），而且它还为在不利条件下使用提供了IP67保护等级。
EX250系列的自我诊断功能可以帮助您快速找出问题，否则可能造成较长停机时间，带来重大损失。
The EX250 device is built with self-diagnostic features to protect the input blocks from over-current and to detect insufficient voltage supply to the valves.

EX250设备内置了自我诊断功能，以让输入模块受到过电流保护，并可检测出电磁阀电源电压的不足。

EX500 SYSTEM
The true power of a serial system is the amount of flexibility and control it gives you in addition to the significant cost savings. SMC’s latest innovation in serial technology…EX500…gives you the power of decentralized control and the flexibility needed for your design.

EX500系统
串行系统真正的魅力在于它在控制方面具有非常大的灵活性，以及显著地节省成本。SMC开发的EX500让你在设计时可以获得所需的分散控制和灵活性。
Series EX500 consists of a gateway unit that gives decentralized control of 4 branches of 16 inputs and 16 outputs per branch (a total of 128 I/O points!). Series EX500 also harnesses the power of our latest valve manifolds — the Series SV and the VQC valve.

EX500系列包含一个网关单位，它可以对4跟分支进行分散控制，每个分支zui多16个输入和16个输出点（即EX500zui多可包含128个输入输出点）。EX500系列还可应用我们的SV和VQC系列阀岛。

The IP65 rating of all EX500 components will ensure the continued error-free operation of your serial system in just about any environment in which your automation applications are located.
所有的EX500组件为IP65防护等级，这确保您在几乎任何自动化应用的环境中运行串行系统都持续无差错。

FASTER WIRING
接线更快捷
Serial Networks typically communicate through just a few cable connections. Imagine communicating with hundreds of inputs and outputs without having to hard-wire each one back to the PLC or controller.
串行网络通常只通过几个连接电缆进行通信。想象一下，如果有数百个输入和输出点，而无需让每个输入输出点都通过不同的电线连接到PLC或控制器，是多么便捷的一件事。
QUICK INSTALLATION
安装更省时
Installing your machine either as a stand-alone application or part of an entire line is a much quicker process through the use of a Serial Network. The modular components can make your installation as easy as “plug and play”.

无论是作为一个独立的应用还是整条生产线的一部分，通过串行网络，安装机器都更为快速。
模块化组件可以让您的安装过程像“即插即用”一样容易。

SIMPLER MAINTENANCE
维护更简单

Have a problem? Save precious time by merely checking the LED display on the serial unit, which will l you if the device in question is working or not. It sure beats checking every wire and I/O point.
出现了问题？仅仅通过检查串行单元上的LED显示屏就可以知道特定的设备是否出现问题或正常工作，这可以节省宝贵的时间。
它会检查每条线和I/O点的节拍。

Benefits of Serial Network Systems
串行网络系统的好处

FLEXIBLE INSTALLATION
安装灵活

Adding or moving devices can be a tedious and time-consuming task when they're hard-wired, but with a Serial
Network, expansion and modification can be as simple as unplugging a phone in the den and reconnecting it in the kitchen!

使用传统的连接系统，添加或移除设备是一个繁琐和费时的任务，但使用串行网络，增加和修改设备简单到就像从书房拔出线然后重新插到厨房一样。
SMALLER SIZE
占地更小
Reducing the number of wires from hundreds (or even thousands) to a few will make a huge difference in your
footprint space. An additional benefit is not having as many I/O cards to deal with.
由于从原来的数百（甚至数千）条线减少到只有几根线，这大大减小了安装空间。另外一个好处就是不再需要去处理许多I/O卡了。

LOWER COST OF OWNERSHIP
生产成本更低
Imagine having fewer wires to number, route, and terminate…fewer I/O cards for your PLC…faster and more effective maintenance. A Serial Network system can achieve all of the above and more. It all adds up to greater added value.
想象一下，只有很少的电线、路线、终端...少量用于PLC的I/O卡...更加快捷的维护性。这些串行网络系统可以实现，并且还远不止于此。这一切都增加了更大的附加值.
