ČSN EN 61158-5-3 ed. 3 The fieldbus application layer (FAL) provides user programs with a means to access the fieldbus communi-cation environment. In this respect, the FAL can be viewed as a "window between corresponding application programs." This standard provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to fieldbus. The term "time-critical" is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life. This standard defines in an abstract way the externally visible service provided by the fieldbus application layer in terms of an abstract model for defining application resources (objects) capable of being manipulated by users via the use of the FAL service, the primitive actions and events of the service, the parameters associated with each primitive action and event, and the form which they take and the interrelationship between these actions and events, and their valid sequences. The purpose of this standard is to define the services provided to the FAL user at the boundary between the user and the application layer of the fieldbus reference model, and Systems Management at the boundary between the application layer and Systems Management of the fieldbus reference model.

ČSN EN 62734 This International Standard specifies a method of reliable and secure wireless operation for non-critical moni-toring, alerting, supervisory control, open loop control, and closed loop control applications. This standard defines a protocol suite, including system management, gateway considerations, and security specifications, for low-data-rate wireless connectivity with fixed, portable, and slowly-moving devices, often operating under severe energy and power constraints. The application focus of this standard is the performance needs of process automation monitoring and control, where end-to-end communication delays on the order of 100 ms can be tolerated.

ČSN ETSI EN 301 649 V2.3.1 The present document defines the standard for packet radio services for Digital Enhanced Cordless Telecommunications (DECT) systems conforming to ETSI EN 300 175-1 [1] to ETSI EN 300 175-8 [8]. It is the basis of profiles, which define more specific applications (Application Specific Access Profiles ASAPs), aimed at the connection of terminals supporting packet data services to a fixed infrastructure, both private and public. DECT Packet Radio Service defines several operation modes, named Classes, and several transported services and protocols, that may be frame relay or character oriented. " Class 1 does not use a network layer C-plane and provides a service similar to a Wireless Local Area Network. " Class 2 implements full DPRS capabilities, including complete C-plane with call control and mobility management, and provides all capabilities of the packet service of public cellular networks (i.e. GPRS). Both services Class 1 and Class 2 support multiberaer and asymmetric connections, and implement Management Entity procedures intended to achieve maximum performance, optimal efficiency and minimal access times. " Class 3 and Class 4 are simplified modes intended for auxiliary data services in voice terminals or other moderate rate data services. The annexes to the present document contain the conventions for interworking of the frame-relay and character oriented services, as well as, other relevant information. The following services are defined in the present document: Frame relay services: " LAN IEEE 802.3 [13] (also known as ISO/IEC 8802-3), (clause B.4). " LAN IEEE 802.5 [14] (also known as ISO/IEC 8802-5), (clause B.5). " Internet Protocol (IP) [15], (clause B.6). " Point to Point Protocol (PPP) [16], (clause B.7). " Generic interworking (clause B.8) that allows the direct transport of other protocols. Character Oriented Services: " V.24 asynchronous interface, including a Packet Assembler and Disasembler (PAD) module (annex C). The present document defines the additional requirements on the Physical Layer (PHL), Medium Access Control (MAC) layer, Data Link Control (DLC) layer and Network (NWK) layer of DECT. The standard also specifies Management Entity (ME) requirements, which ensure the efficient use of the DECT spectrum. The present document includes New Generation DECT, a further development of the DECT standard introducing wideband speech, improved data services, new slot types and other technical enhancements.

ČSN ETSI EN 300 175-5 V2.6.1 The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). The present document specifies the Network (NWK) layer. The NWK layer is part 5 of the ETSI EN 300 175 and layer 3 of the DECT protocol stack. The present document only specifies the C-plane (control plane) of the DECT NWK layer. It contains no specification for the U-plane (user plane) because the U-plane is null for all services at the DECT NWK layer. The C-plane contains all of the internal signalling information, and the NWK layer protocols are grouped into the following families of procedures: - Call Control (CC); - Supplementary Services (SS); - Connection Oriented Message Service (COMS); - ConnectionLess Message Service (CLMS); - Mobility Management (MM); - Link Control Entity (LCE). The present document uses the layered model principles and terminology as described in Recommendations ITU T X.200 [i.3] and X.210 [i.4].

ČSN EN 62680-2-1 This document defines an industry-standard USB. The specification describes the bus attributes, the protocol definition, types of transactions, bus management, and the programming interface required to design and build systems and peripherals that are compliant with this standard. The goal is to enable such devices from different vendors to interoperate in an open architecture. The specification is intended as an enhancement to the PC architecture, spanning portable, business desktop, and home environments. It is intended that the specification allow system OEMs and peripheral developers adequate room for product versatility and market differentiation without the burden of carrying obsolete interfaces or losing compatibility. The specification is primarily targeted to peripheral developers and system OEMs, but provides valuable information for platform operating system/ BIOS/ device driver, adapter IHVs/ISVs, and platform/adapter controller vendors. This specification can be used for developing new products and associated software.
