Introduction
This section GB/T 15969 Part 6, should be combined with the rest for the programmable logic controller and related peripheral devices
read.
Function as a safety programmable logic controller (FS-PLC) product standards, this section may be considered covered by the programmable controller
And related peripheral devices.
If you can not meet the requirements of Part 4 of this chapter, you can not declare compliance with GB/T Part of 615,969.
GB/T 15969 Part 1 defines a generic term. More specific terms are defined in each section.
For the IEC 61508-1.2010, consistent with 1.1, this section contains the IEC 61508-1, IEC 61508-2 and IEC 61508-3
With programmable controllers and their associated peripherals product-specific requirements related to.
IEC 61508 is based on the structure of this part of the principle. However, because some aspects are not directly linked, and therefore require different treatments.
To some extent, this is due to the need to deal with hardware, software, firmware, etc. in a separate document.
As part of the framework of the IEC 61508-1.2010 Fig. 2, there is renumbered as 1, and it has been adjusted to show
FS-PLC for how the overall E/E/PE safety-related system security lifecycle. Although Figure 1 includes a sensor block 10, the logical sub
And the final element of the system (e.g., actuators), but from the perspective of IEC 61508-1, herein incorporated by reference to FIG. 3 projecting FS-PLC.
Likewise, from the perspective of this section, the implementation phase 1 block 10 only reflects the logic subsystem.
Note 1. For clarity, function and safety verification, security management functions and activities related to the functional safety assessment is not shown in the drawings, but these are the overall
The, E/E/PE system and the various stages of the life cycle of software security.
Within the stage represented by block 11 is not in the scope of this standard. Note 2.
Note 3. IEC 61508-2 and IEC 61508-3 relates to block 10 (to achieve), but also relates to the relevant part of block 13, block 14 and programmable electronic box 15
Aspects (hardware and software).
Note 4. See IEC 61508-1 Table 1 describes the objectives and scope of the various stages of each block represents.
Note 5. The overall operation, maintenance, repair modifications, modifications and decommissioning or disposal of the technical requirements needed to be defined as E/E/PE safety-related systems and components and metadata

Programmable controllers - Part 6. Functional safety
1 Scope
This section GB/T 15969 requirements for GB/T 15969.1 defined programmable logic controller (PLC) and their associated peripherals
Equipment requirements, and its purpose is logical subsystems for electrical/electronic/programmable electronic (E/E/PE) safety-related systems. Subject to this section
Programmable logic controller and related peripheral equipment requirements considered to be suitable for E/E/PE safety-related systems, known as functional safety can
Programmable logic controller (FS-PLC). FS-PLC typically hardware (HW)/software (SW) subsystem. FS-PLC may also contain software
Components, such as pre-defined function blocks.
E/E/PE safety-related systems typically comprise sensors, actuators, software, and logical subsystems. This part of the IEC 61508 standard to
Product-specific implementation requirements, compliance with this section to conform to IEC 61508 with all applicable requirements for the FS-PLC. IEC 61508 standard
Registration system is standard, and is divided into Part principles IEC 61508 standard applications in the FS-PLC provides a product-specific requirements.
When used as part of the FS-PLC E/E/PE safety-related systems, this section only deals FS-PLC functional safety and security Ends
Integrity requirements. Function of the final application functional safety requirements overall E/E/PE safety-related systems and E/E/PE safety-related systems
Within the scope of the definition of security requirements are not contained in this section, but they are entered in this section. For application-specific information, the reader can refer to it
His standards, such as GB/T 21109 standard, GB 28526 and GB/T 16855 standard.
This section does not include the FS-PLC universal security requirements, such as electric shock and fire hazard and GB/T 15969.2 specified in the relevant requirements.
This section applies to Safety Integrity Level (SIL) is not higher than SIL3 capability of FS-PLC.
The purpose of this section is.
a) Establishment and description FS-PLC safety lifecycle components, and IEC 61508-1 ~ IEC 61508-3 General Safety and Health identified
Consistent with the life cycle;
b) the establishment and description FS-PLC hardware and software on E/E/PE safety-related systems functional safety and safety integrity requirements
Claim;
c) the establishment of the FS-PLC evaluation methods, according to this section the following parameters/criteria.
1) FS-PLC can be achieved Safety Integrity Level (SIL) statement;
2) probability of failure on demand (PFD) value;
3) the average frequency of dangerous failure per hour (PFH) values;
4) Safe Failure Fraction (SFF) value;
5) Hardware Fault Tolerance (HFT) value;
6) Diagnostic coverage (DC) value;
7) Verify that the specified FS-PLC manufacturer's safety lifecycle process in place;
8) define the security status;
9) for the prevention and control of systematic failures of measures and technologies;
10) For each failure mode in this part of the process, the functional behavior of state failure.
d) establish definitions and identifies the selection and application FS-PLC and related peripheral devices of the main characteristics related.
This part is mainly used for FS-PLC manufacturer. User requirements document, this section also contains a key role in FS-PLC users.
