This recommended practice defines the functions, performance, interface, and environmental conditions of vital computers used in rail transportation systems such as railways, metros, light transport, and trams. This recommended practice is applicable to vital computers for onboard and wayside equipment. This recommended practice is not applicable to the application systems which are developed based on vital computers and does not define specific safety targets for application systems, but the… read more safety-related conditions for application systems are proposed. It is difficult to regulate internal structure and technical realization of vital computers, because of the great diversity that exists. In order to encourage technical competition and prompt the development of technology and industry, this recommended practice does not constrain or recommend the internal structure and technical realization of vital computers. Only the preliminary interface is defined in this recommended practice, on a function level. The detailed interface of a vital computer is not covered and can be defined in the form of external interface specifications. Compliance with the provisions of this recommended practice does not guarantee or ensure safety, security,health, or environmental protection. Users are responsible for observing all applicable legal and regulatory requirements. read less

The basic CAMAC specification (see Ref [1]) defines a single CAMAC operation as the activity which oc curs in response to a single CAMAC command. This activity may consist of the transfer of a single data word bet ween a CAMAC module and computer memory or the changing of the status of a module [for example, F (26), F (24)] or return of a value for Q as the result of a test made on the module, or any compatible set of the previously named activities. A block transfer is defined as a sequence of… read more single CAMAC operations involving data which the user specifies by a command said to be of a higher level than one which specifies a single CAMAC operation. The higher level command contains all the information required for the specification of the desired sequence of single CAMAC command s and is interpreted by a channel which governs the activity on the CAMAC highway. Control information such as the readiness of the computer to participate in a data transfer, the state of the CAMAC Q line and the state of certain LAMs (Look-at-Me's) or special synchronizing signals must be made available to the channel. The use made of the control information by the channel defines the block-transfer mode. If a module is to influence the sequence of ope rations within a block transfer, then it must have the features required by the algorithm. read less

This recommended practice views the CASE adoption process as more than the selection of CASE tools. The CASE adoption process consists of the activities by which an organization identifies appropriate CASE tools and related technologies and introduces them into general use. The steps of a successful CASE adoption process include the following: a) Defining CASE needs b) Evaluating and selecting CASE tools c) Conducting a pilot d) Fostering routine use of the tool A successful CASE adoption… read more process is not limited solely to tool use. Rathere, it embraces the planning and implementation of an entire set of technical, organizational, cultural, and management processes necessary to achieve the required organizational improvements. It is founded upon a strong understanding of what CASE tools can and cannot do for the organization. Steps a) through d) above are appropriate for a wide range of computing organizations, including those that develop management information systems and those that develop scientific and technical systems. This recommended practice can also be of benefit to government and commercial software organizations. Specific situations may influence the manner in which CASE adoption is performed. For example, when a specific tool is mandated by customer preference or contract requirements, adoption steps will require tailoring to reflect the predetermined nature of tool selection. In other cases, the relative simplicity or complexity of the tool, the degree to which the tool supports or conflicts with existing processes, the required degree of integration with other tools, and the characteristics and experience of the targeted users, may lead to the tailoring of the adoption process. read less

This standard defines a Serial Highway (SH) system using byte-organized messages, and configured as a unidirectional loop to which are connected a system controller and up to sixty-two CAMAC* crate assemblies in accordance with ANSI/IEEE Std 583-1982, [Modular Instrumentation and Digital Interface System (CAMAC*)] or other controlled devices. The highway transfers data and control information in either bit-serial mode (using one data signal and a bit-clock signal) or byte-serial mode (using… read more eight data signals and a byte-clock signal).

The Dataway defined in ANSI/IEEE Std 583-1982, Modular Instrumentation and Digital Interface System, is the basis for all CAMAC* systems. It provides the means of interconnection between modules and a crate controller within one crate. This standard defines the CAMAC Parallel Highway Interface System for interconnecting up to seven CAMAC crates (or other devices) and a system controller. The Parallel Highway, so called because the data bits are transmitted along the Highway in parallel, is… read more capable of handling higher data rates than nonparallel highways. However, in some applications, for example, where there are long distances between crates or where simplicity of interconnections is particularly important, the Serial Highway of ANSI/IEEE Std 595-1982, Serial Highway Interface System (CAMAC), may be more suitable. read less
