SafetyStandards provides the supported safety standards. Examples are:
- IEC 61800-5
- IEC 61508
FunctionalSafetySilLevel provides the information to the supported safety integrity level (SIL) according to IEC 61508 standard. The values of the MultiStateValueDiscreteType variable are defined Table 156 and shall be used. Additional values are added in the specification in according to the standard. Manufacturer-specific extensions are not foreseen.
FunctionalSafetyPerformanceLevel provides the value used to define the ability of safety-related parts of control systems to perform a safety function under foreseeable conditions. The values of the MultiStateValueDiscreteType variable are defined in Table 156and shall be used. Additional values are added in the specification in according to the EN ISO 13849 standard. Manufacturer-specific extensions are not foreseen.
FunctionalSafetyCategory provides the information to the existing functional safety category. The values of the MultiStateValueDiscreteType variable are defined in Table 156 and shall be used. Additional values are added in the specification in according to the ISO 13849-1 standard. Manufacturer-specific extensions are not foreseen.
