Organise the creation of safe machinery with the V model
13264
Summary
► Define, observe, check and document the workflow steps in the V model
► Define responsibilities for tasks
► Define a person responsible for safety technology (Functional Safety Manager)
Every machine manufacturer should define the responsibilities for the respective tasks within his
company through organisational measures. This is independent of the work steps ...
• for machine design
• for the creation of the application program for the SafetyController
A staff member responsible for the safety technology (FSM = Functional Safety Manager) should also
be appointed. In larger companies this role is assigned to staff members who have the primary
responsibility.
► Tasks:
• prepare specifications
• prepare safety concept and machine specifications
• prepare functional specifications
• determine or calculate the reliability of the safety function
• document all work steps
• archive the documentation and keep it during the life cycle of the machine
► The execution and verification of a task must not be performed by the same staff member!
• create and verify specifications
• create and verify machine specifications
• create and verify the different safety-related function units
• verify the interaction of the function units
The 4-eye principle is typically applied here.
To illustrate this structure in graphic form the V model can be applied. The machine manufacturer
adds the corresponding details and responsibilities to each work step of a particular application. The
machine manufacturer could also
– depending on the work packages – create several organisational
units based on the V model.
It is important that this organisational structure is documented and archived.
