更多>1、Profibus與PROFINET有什么不同?是否有獨(dú)立接口?
What is the diFFerence between PROFIBUS and PROFINET? Is there any independent interface?
回答:
PROFIBUS是一種基于通信系統(tǒng)的現(xiàn)場總線。PROFINET是一種基于通信系統(tǒng)的以太網(wǎng)并提供一種較簡單的方法將自動控制系統(tǒng)集成在廣大的公司IT系統(tǒng)中,如MES(制造執(zhí)行系統(tǒng))或ERP(企業(yè)資源計劃)。
自動控制系統(tǒng)供應(yīng)商同時為PROFIBUS和PROFINET提供接口。
Answer:
PROFIBUS is a Fieldbus based communication system. PROFINET is an Ethernet based communication system and oFFers an easier way to integrate the Automation systems into the company-wide IT-Systems like MES (Manufacturing Execution Systems) or ERP (Enterprise Resource Planning).
The supplier of Automation systems are offering Interfaces for PROFIBUS as well as for PROFINET.

7、目前“樓宇智能化”也是大勢所趨,現(xiàn)場總線在這方面的推廣應(yīng)用有無考慮?
“Building Inligence” is definiy a tendency. Are there any consideration given in this regards towards the promotion of such technology?
回答:
PROFIBUS主要應(yīng)用于工廠及過程行業(yè)。它也可以用于樓宇自動控制。關(guān)鍵問題是該設(shè)備*化樓宇自動控制主要具有的廣泛使用這種分支的總線系統(tǒng)的接口(例如歐洲安裝總線(EIB),當(dāng)?shù)剡\(yùn)行網(wǎng)絡(luò)(LON),bacNET)。
Answer:
PROFIBUS is mainly used in the factory and the process industry. It also can be used in building automation. The key issue is that the devices that are optimized for building automation have mainly interfaces of bus systems that are widely used in this branche (e.g. European installation bus (EIB), Local operating network (LON), bacNET).
8、組態(tài)軟件,例如step7,其與資產(chǎn)管理軟件是不是有相似之處?不同的地方是什么?
For the configuration software, take S7 for example, dose it share similarities with PAM? What’s the difference?

9、PROFIBUS協(xié)議與標(biāo)準(zhǔn)可到什么機(jī)構(gòu)索???
Where can we obtain PROFIBUS Protocol and Standard?
回答:
通常只有產(chǎn)品系統(tǒng)供應(yīng)商及測試實(shí)驗(yàn)室需要PROFIBUS協(xié)議與規(guī)格。PROFIBUS標(biāo)準(zhǔn)本身可通過IEC或國家標(biāo)準(zhǔn)化機(jī)構(gòu)索取。
除了該文獻(xiàn),像“PROFIBUS快速入門”也充足供應(yīng)。
Answer:
Usually only product and system supplier as well as test labs need PROFIBUS protocols and specifications. The PROFIBUS standard itself is available by IEC or the national Standardization Organizations.
In addition to this literature like “Rapid Way to PROFIBUS” is available and sufficient.
10、談到現(xiàn)場總線的使用情況時會說某種總線,比如PROFIBUS及Interbus已安裝了2000多萬個節(jié)點(diǎn),這里“節(jié)點(diǎn)”指什么?這意味著它們應(yīng)用于相關(guān)領(lǐng)域的生產(chǎn)嗎?
PROFIBUS and Interbus have reached over 20 million nodes together. Does 20 million nodes mean point? Does it imply that they are used in the production related fields?
回答:
術(shù)語“節(jié)點(diǎn)”是指“設(shè)備的數(shù)量”而不是I/O點(diǎn)。
只有PROFIBUS能夠應(yīng)用于工廠自動化和過程自動化。大約210萬安裝了1260萬PROFIBUS節(jié)點(diǎn)用于過程自動化應(yīng)用中。
Answer:
The term “node” is identical with “number of devices” but not with IO- points.
Only PROFIBUS can be used for Factory Automation as well as for Process Automation. About 2.1 Million of the installed 12.6 Million PROFIBUS nodes are used for Process Automation applications.
11、PROFIBUS-PA是如何解決冗余問題?
For PROFIBUS PA, how to solve the redundancy problem?
回答:
PROFIBUS具有一個從站設(shè)備擁有兩個物理總線接口的冗余理念。這兩個總線接口能夠
a) 通過一根總線電纜(從站冗余)連接主站
b) 通過一根總線電纜(從站冗余和主站冗余,也稱作臨時冗余)連接兩個主站(初始主站及后備主站)
c) 通過兩根獨(dú)立的總線電纜(系統(tǒng)冗余)連接兩個主站(初始主站及后備主站)
該理念僅適用于作為物理層的RS485接口。PROFIBUS PA典型地與曼徹斯特總線電力傳輸(MBP)運(yùn)行,通過總線電纜產(chǎn)生動力推動設(shè)備,因此不會有兩個總線接口的冗余從站。所以PROFIBUS PA中可使用兩個獨(dú)立的同種從站。該理念依照依賴于DCS的a),b)或c)進(jìn)行應(yīng)用。
Answer:
PROFIBUS has a redundancy concept where one slave device has two physical bus interfaces. These two bus interfaces can be
a) Connected to one master via one bus cable (slave redundancy)
b) Connected to two masters (primary master and backup master) via one bus cable (slave redundancy and master redundancy, also called flying redundancy)
c) Connected to two masters (primary master and backup master) via two separate bus cables (system redundancy).
This concept works only for RS 485 interface as physical layer. PROFIBUS PA works typically with Manchester Bus Powered transmission (MBP) where the devices are powered via bus cable and therefore there is no redundant slave having two bus interfaces. Hence in PROFIBUS PA two separate identical slaves are to be used. The concept that is applied according a), b) or c) depends on the DCS.
12、電力系統(tǒng)產(chǎn)品可以采用PROFIBUS嗎?
Are there any PROFIBUS PA application cases for the power stations?
回答:

13、問一個非技術(shù)的問題。據(jù)我觀察參加本次研討會的有不少高校學(xué)生,說明現(xiàn)場總線也是高校學(xué)生研究的熱點(diǎn)之一。作為其中一員,我想請問唐教授CPCC有沒有開展一些面向在校碩士、博士的實(shí)踐和培訓(xùn)活動?還想問在座的各大公司如西門子,ABB,E+H有沒有提供一些現(xiàn)場總線方面的實(shí)習(xí)或培訓(xùn)機(jī)會?
I have noticed that there are some university students that are participating in this seminar, which indicates that the filed bus field has been the hot area for the students from the universities to pay close attention to. As one of them, I want to address this question to Professor Tang Jiyang from CPCC regarding the practical training and other activities that are directing towards the students working on their Master degrees and Ph.D.s degrees. And what about the companies like Siemens, ABB and E+H?
回答(E+H):
E+H方面還沒有為學(xué)生開設(shè)專門的PROFIBUS培訓(xùn)。E+H對PROFIBUS的支持可以直接同Lianwang.Dou(lianwang.dou)。
回答(西門子):
西門子提供有關(guān)英語(中文正在建立中)PROFIBUS和PROFINET基于培訓(xùn)。請參閱:(/htm. 76/f 11 simaticwbt.html)。
當(dāng)然,每個當(dāng)?shù)匚鏖T子辦事處都會提供有關(guān)PROFIBUS和PROFINET支持。
Answer by E+H:
There are no special PROFIBUS trainings for students from E+H side. For PROFIBUS support from E+H side please feel free to contact directly Mr. Lianwang Dou (lianwang.dou).
Answer by Siemens:
Siemens offers web based training for PROFIBUS and PROFINET in English language (Chinese language is under work). Please see: (/html_76/f_11_simaticwbt.html).
Of course every local Siemens office offers support for PROFIBUS or PROFINET.
14、就發(fā)展趨勢來講,APC*控制算法,已內(nèi)嵌到DCS的現(xiàn)場控制站(如Emerson的Delta V),SIEMENS,ABB的DCS現(xiàn)在能提供類似的技術(shù)嗎?
As far as the future trend, APC has already been imbedded into the DCS controller in the field (For example, Emerson’s Delta V), Can the DCS from either Siemens or ABB now provide the technology similar to it?
回答(西門子):
自5.0版本(2001年)以來,西門子DCS Simatic PCS7就可以使用*過程控制算法(APC)。
Answer by Siemens:
Advanced Process Control (APC) id available for Siemens DCS Simatic PCS7 since Version 5.0 (2001).
15、如果APC算法內(nèi)嵌到DCS的控制站,那么控制站的基礎(chǔ)控制算法(PID等)若能內(nèi)嵌到帶現(xiàn)場總線的現(xiàn)場設(shè)備,勢必大大增控制站的控制和優(yōu)化功能。FF目前已具備在現(xiàn)場設(shè)備內(nèi)嵌PID的功能塊的功能,PROFIBUS-PA目前沒有這樣的功能。PROFIBUS-PA今后會解決這個問題嗎?
Now that APC is imbedded into the DSC controller, then if PID would be able to be imbedded into the field devices, it would be enhance the control and optimization of the controllers. FF, so far, is capable of imbedding the PID module block. PROFIBUS PA currently has no such functionality. Will PROFIBUS PA solve this problem? There seems nothing mentioned regarding this area in today’s seminar.
回答(西門子):
控制站沒有必要運(yùn)用PROFIBUS PA,現(xiàn)場總線性能充足并不斷增強(qiáng)確保冗余的自動控制的有效性。
