Emergency Requirement

Text

This field describes the details of handling the failure of SIS in case of emergency. On the datasheet, this field appears as a text box, in which you can enter the SIS handling in case of emergency. The description may detail manual override of SIS.
Is Default Logical Indicates whether the record is the default one. If set true, then the SRS Template is a default template for the category supplied by GE Digital.
Last Modified By Character The name of the user who last modified the record. On the datasheet, this field is disabled and updated automatically whenever the record is modified.
Last Modified Date Date The date on which the record was last modified. On the datasheet, this field is disabled and populated automatically.
Normal Operation Requirement Text The behavior of the SIS during normal operation. On the datasheet, this field appears as a text box, in which you can enter the normal operating behavior that the SIS is designed to handle.
Revision Number Numeric A number that represents the number of times the record has been revised. On the datasheet, this field is disabled and populated.
SIF Demand Mode of operation Text

The demand rate exerted on the safety system.

  • Low Demand Mode: Safety Function demand rate is less than or equal to once a year.
  • High Demand Mode: Safety Function demand rate is greater than once a year.
  • Continuous Mode: Safety Function is operating as a continuous control function.
On the datasheet, this field appears as a text box, in which you can enter the demand rate on the SIS that the SIS is designed to handle.
SIF Protection Mode Text The SIL level used for protecting the asset. (for example, SIL 1, SIL2 or SIL3) On the datasheet, this field appears as a text box, in which you can enter the SIL specifications that the SIS is designed to handle. (example: SIL 1, SIL2 or SIL3)
SRS Methodology Text The methodology used to allocate the safety integrity requirements, depending the necessary risk reduction. (for example, quantitative method (numeric risk reduction) or qualitative method (risk matrix, risk graph) On the datasheet, this field appears as a text box, in which you can enter the methodology used for allocating the safety integrity requirements that the SIS is designed to handle.
SRS Purpose and Scope Text The purpose of the SIS and the details of the coverage. On the datasheet, this field appears as a text box, in which you can enter the SIL purpose and what SIF it is targeted to cover are described.
SRS Standards Used Text The standards used in designing the SRS. On the datasheet, this field appears as a text box, in which you can enter the SIL standard that the SIS design is based on (IEC 61508 or ISA 84).
SRS Template Description Character A description of the record. On the datasheet, this field appears as a text box labeled Description, in which you can enter a description of the record.
SRS Template ID Character The ID of the record. On the datasheet, this field appears as a text box labeled Field ID, in which you can type the ID.
System Definition Text The system under consideration. On the datasheet, this field appears as a text box, in which you can enter the system specifications that the SIS is designed to handle.
