SMC總線技術簡介（中英文對照）

What is Serial Networking technology?
什么是串行網絡系統？

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.

串行網絡系統使用的是串行傳輸，從而使控制器（PC或者PLC）遠程控制本地生產設備。 編程指令由控制器產生，并通過雙線（雙絞電纜）與遠程輸入輸出（遠程I/O）模塊連接。 這些輸入輸出模塊與諸如電磁閥、傳感器、某種類型的儀器等設備相連。

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，為什么串行網絡系統會如此影響你的效益？實際上還得益于串行接口技術，你應該明白串行系統和傳統控制系統之間的差別。

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.

在傳統的控制系統中，I/O卡位于PLC機箱內。所有連接執行器、限位開關、接近開關、監視器等設備的電線都必須反饋到PLC中。這也沒有什么大不了的？嗯，這取決于系統的復雜性以及數以千計的電線。要排除此系統中的故障要耗費巨大的時間和精力。

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.

而在串行網絡系統中，所有的I/O卡和數量龐大的電線被一根電纜、一個掃描器和一個串行接口單元及輸入設備取代。故障可以快速排除，因為在串行網絡系統中內置了診斷功能。

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的串行網絡（又稱串行接口）產品，系統集成商和工程師可以根據需要自由設計*的系統。
SMC’s modular approach to solving system control problems provides for maximum flexibility. And with SMC’s unequalled reputation for high quality manifolds and valves, you know the entire system will optimize the integrity of your design. Series EX250 and EX500 Serial Network components are just two examples of our
commitment to provide these solutions to your control system problems…

SMC模塊化的方法為解決系統控制問題提供了zui大的靈活性。使用SMC聲譽的閥島和閥，將會使你的整個系統的設計得到zui大的優化。下面僅以EX250和EX500系列串行網絡組件為例來說明我們如何提供這些解決方案來控制系統的問題......
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.

這種先進的系統不僅具有32個傳感器輸入點（以及32電磁閥輸出點），而且它還為在不利條件下使用提供了IP67保護等級。
EX250系列的自我診斷功能可以幫助您快速找出問題，否則可能造成較長停機時間，帶來重大損失。
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設備內置了自我診斷功能，以讓輸入模塊受到過電流保護，并可檢測出電磁閥電源電壓的不足。

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系統
串行系統真正的魅力在于它在控制方面具有非常大的靈活性，以及顯著地節省成本。SMC開發的EX500讓你在設計時可以獲得所需的分散控制和靈活性。
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系列包含一個網關單位，它可以對4跟分支進行分散控制，每個分支zui多16個輸入和16個輸出點（即EX500zui多可包含128個輸入輸出點）。EX500系列還可應用我們的SV和VQC系列閥島。

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組件為IP65防護等級，這確保您在幾乎任何自動化應用的環境中運行串行系統都持續無差錯。

FASTER WIRING
接線更快捷
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.
串行網絡通常只通過幾個連接電纜進行通信。想象一下，如果有數百個輸入和輸出點，而無需讓每個輸入輸出點都通過不同的電線連接到PLC或控制器，是多么便捷的一件事。
QUICK INSTALLATION
安裝更省時
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”.

無論是作為一個獨立的應用還是整條生產線的一部分，通過串行網絡，安裝機器都更為快速。
模塊化組件可以讓您的安裝過程像“即插即用”一樣容易。

SIMPLER MAINTENANCE
維護更簡單

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.
出現了問題？僅僅通過檢查串行單元上的LED顯示屏就可以知道特定的設備是否出現問題或正常工作，這可以節省寶貴的時間。
它會檢查每條線和I/O點的節拍。

Benefits of Serial Network Systems
串行網絡系統的好處

FLEXIBLE INSTALLATION
安裝靈活

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!

使用傳統的連接系統，添加或移除設備是一個繁瑣和費時的任務，但使用串行網絡，增加和修改設備簡單到就像從書房拔出線然后重新插到廚房一樣。
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.
由于從原來的數百（甚至數千）條線減少到只有幾根線，這大大減小了安裝空間。另外一個好處就是不再需要去處理許多I/O卡了。

LOWER COST OF OWNERSHIP
生產成本更低
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，只有很少的電線、路線、終端...少量用于PLC的I/O卡...更加快捷的維護性。這些串行網絡系統可以實現，并且還遠不止于此。這一切都增加了更大的附加值.
