This document replaces GB/T 16679-2009 "Industrial systems, devices and equipment and industrial product signal codes" and GB/T 16679-Compared with 2009, in addition to structural adjustments and editorial changes, the main technical changes are as follows.

--- Added terms. information object, data object, signal name, signal connection, signal connection network, signal connection identifier, signal Transmission media, domains, signal classification codes, signal connection characteristics; (see Chapter 3)

--- Deleted the terms. signal connection line, signal connection chain, signal type, signal variable, data point, data item, form (see 2009 3 of the 2011 edition).

--- Changed the basic rules (see Chapter 4, Chapter 4 of the 2009 edition);

--- Changed the signal code (see Chapter 5, Chapter 5 of the 2009 edition);

--- Changed the signal identification in the signal connection network (see Chapter 6, Chapter 6 of the 2009 edition);

--- Added signal identification of data exchange interface (see Chapter 7);

--- Deleted the application (see Chapter 8 of the 2009 edition);

--- Deleted the consistency classification (see Chapter 9 of the 2009 edition);

--- Added letter codes for signal codes (see Appendix A).

Basic Rules.

Introduction

The signal code is closely associated with the signal throughout its life cycle, which starts from the design phase and ends when the signal is no longer used.

until.

GB/T 16679 currently consists of one part.

--- Part 1: Basic rules. Aims to establish rules and requirements for signal codes.

When the device reconstruction causes the signal transmission medium to change, in order to keep the semantics of the signal identification unchanged, the signal identification will not be changed.

The signal represents information. For the purpose of communication, the information is in the form of data. The information is more or less complex. In simple applications, in this example, the information can be represented using a single Boolean variable without the need for an internal structure. In more complex application cases, such as when computers communicate, information can be transmitted by encapsulating the internal structure in complex objects using appropriate protocols.

Common technologies and protocols are implemented in different ways. Figure 1 shows an example related to terminology.

1 Scope

This document provides the rules for the code formation of signal identification and signal connection, including the code for power supply.

This document applies to all types of signals in industrial systems, devices and equipment and industrial products. It does not involve the information aspects of the signal.

Physical realization.

The general principles of information presentation on the human-machine interface are outside the scope of this document. This document does not apply to wiring, terminals, bushings, and other hardware connections.
