3、med December 21, 1990Approved December 15, 1981American National Standards Institute1Computer Automated Measurement and ControlIEEE Standardsdocuments are developed within the Technical Committees of the IEEE Societies and the StandardsCoordinating Committees of the IEEE Standards Board. Members of
4、the committees serve voluntarily and withoutcompensation. They are not necessarily members of the Institute. The standards developed within IEEE represent aconsensus of the broad expertise on the subject within the Institute as well as those activities outside of IEEE whichhave expressed an interest
5、 in participating in the development of the standard.Use of an IEEE Standard is wholly voluntary. The existence of an IEEE Standard does not imply that there are no otherways to produce, test, measure, purchase, market, or provide other goods and services related to the scope of the IEEEStandard. Fu
6、rthermore, the viewpoint expressed at the time a standard is approved and issued is subject to changebrought about through developments in the state of the art and comments received from users of the standard. EveryIEEE Standard is subjected to review at least once every ve years for revision or rea
7、frmation. When a document ismore than ve years old, and has not been reafrmed, it is reasonable to conclude that its contents, although still ofsome value, do not wholly reect the present state of the art. Users are cautioned to check to determine that they havethe latest edition of any IEEE Standar
8、d.Comments for revision of IEEE Standards are welcome from any interested party, regardless of membership afliationwith IEEE. Suggestions for changes in documents should be in the form of a proposed change of text, together withappropriate supporting comments.Interpretations: Occasionally questions
9、may arise regarding the meaning of portions of standards as they relate tospecic applications. When the need for interpretations is brought to the attention of IEEE, the Institute will initiateaction to prepare appropriate responses. Since IEEE Standards represent a consensus of all concerned intere
10、sts, it isimportant to ensure that any interpretation has also received the concurrence of a balance of interests. For this reasonIEEE and the members of its technical committees are not able to provide an instant response to interpretation requestsexcept in those cases where the matter has previous
11、ly received formal consideration.Comments on standards and requests for interpretations should be addressed to:Secretary, IEEE Standards Board345 East 47th StreetNew York, NY 10017USAiiiForeword(This Foreword is not a part of ANSI/IEEE Std 675-1982, IEEE Standard, Multiple Controllers in a CAMAC Cra
12、te.)This standard makes provision for the use of auxiliary controllers in a CAMAC crate to extend the capabilities andelds of application of the CAMAC modular instrumentation and interface system of ANSI/IEEE Std 583-1982,Modular Instrumentation and Digital Interface System (CAMAC). (Also Report EUR
13、 4100e of the Commissions ofthe European Communities.) The report on which this document is based (Dept of Energy Report DOE/EV-007), wasprepared by the NIM Committee of the United States Department of Energy* and the ESONE Committee of EuropeanLaboratories*. Corresponding documents are ESONE Report
14、 EUR 6500e and IEC Publication 729 of theInternational Electrotechnical Commission.Auxiliary Controllers (ACs), located in several crates on a CAMAC Command Highway (Parallel Branch or Serial),can provide the user with an extremely effective distributed processing capability. This capability is usef
15、ul in both dataacquisition and automatic control systems where parallel processing is desirable. Auxiliary controllers can be ofvarious degrees of sophistication, and some may include processor elements for increased autonomy from centralcomputers.A further extension of the AC-based CAMAC system may
16、 include a special communication channel direct from an ACto another element in the system. High-speed block transfer of data can be effected to and from the AC in such a case.To permit use of the ACs in CAMAC crates, this report denes the hardware and protocol so as to:1) Provide means for granting
17、 control of the Dataway to auxiliary controllers that request control and to providea priority selection scheme to arbitrate in the case of simultaneous requests from multiple controllers.2) Provide means for the auxiliary controller to address (a) the dedicated module address lines and (b) thededic
18、ated interrupt request LAM (Look-at-Me) lines, all of which terminate only at the crate controllerstation and at the module stations to which they are dedicated.This standard was reviewed and balloted by the Nuclear Instruments and Detectors Committee of the IEEE Nuclearand Plasma Sciences Society.
19、Because of the board applicability of the CAMAC system, this standard was submittedfor review to liaison representatives of numerous societies and committees including the Communications Society,Computer Society, Industry Applications Society, Industrial Electronics and Control Instrumentation Group
20、,Instrumentation and Measurement Group, and the Power Generation and Nuclear Power Engineering Committees ofthe Power Engineering Society.The revision of this standard was in conjunction with the 1981 review (1982 issue) of the entire family of IEEECAMAC standards undertaken to incorporate existing
21、addenda and corrections into the standards.At the time of approval of this standard, the membership of the Nuclear Instruments and Detectors Committee of theIEEE Nuclear and Plasma Sciences Society was as follows:D.
