(Scientific), The object of this technical report is to propose a software and hardware interface standard of dynamic modules.The dynamic modules addressed are defined in the IEC 62343 series. Inc., Normative references undated references, the latest edition of the referenced document (including any amendments)applies. None. Survey outline 3.1 Survey contents a) Types of dynamic modules (supplier/user) b) Standard of the control interface which is planned to be offered from now on (supplier) c) (p Standard of the control interface which is requested and used (user) e) Comments aboutthe standard of a typical control interface (supplier/user) f) Opinions about standardization of the control interface (supplier/user) 3.2 Survey conditions a)Requestto55companies (81 departments: users, suppliers,representatives of suppliers) b)Received28 effectivereplies Users: 12companies Suppliers: 13companies Both: 3companies c) Survey period FromSeptembertoOctober2004 4 Interface definition The layer structure of the interface of a dynamic module is shown in Figure 1. There are an optical component and two microprocessors for control, and there are three interfacing points: interfaceA,interfaceB andinterface C. yrighted I material - 9 - TR62343-6-2@IEC:2013(E) licensed to BR Demo b Interface A is the electric fundamental interface portion of the core optical device and the optical component.It is,for example,analogueinterface,the electric powerdirectly impressed to a conductor or a motor.Moreover, it isthought that many proprietary specifications are changed according to the TTL/CMOs level digital interfaces with a simple conversion circuit. This interface point is defined as the fundamental interface group. As a second interface group, there are dual port RAM and 2C, etc., which are used at interface B. These interfaces have spread widely and are adopted as standard interfaces in equipment by the system side. The interface used at interface C is classified into a third interface group. There is a bus form which is original with a system vendor etc.,and Ethernet and PCl/compact-PCl bus are classified into this interface C. (Sci In addition, traditional interfaces such as GP-IB and RS232C are also classified as interface C. RS485 andUSB,which are considered a substitution for RS232C,arealso classified into this. Inc. Since these interfaces are easy to treat for use with PC, their use has spread widely. Subsystem/unit/board Dynamic module Component .com.

NOTE investigated. Since 2oo4, WSS (wavelength selective switch) has been one of the most attractive dynamic modules. It is found that the software and hardware interface of WSs is only DP-RAM. Moreover, the other dynamic modules have continued to use almost the same interfaces as those in 2oo4.This result is identical to the result shown in nitted. the first edition of IEC 62343-6-2.
