Test Compiler with Virtual Process Link TM


Increasingly stringent standards for software validation in Safety Systems emphasize the need for a modern approach to testing and validation. In order to satisfy both test quality and cost, an integrated approach to logic certification must be implemented throughout the program development life cycle. Furthermore, initial testing efforts should give consideration to a streamlined process of periodical re-certification.

Industry accepted engineering practices rely on extensive test campaigns and documentation of your safety systems and more specifically on your application program before it can go on line.
Those tests should be compliant with the following standards:
 
Osha 29 CFR Part 1910
calls for complete documentation for each inspection and test for your ESD systems
Test date
Name of test engineer/technician
Test results comprehensive description
 ANSI/ISA-84.01
“ 9.7.1 Periodic Functional Test shall be conducted using a documented procedure ”

IEC 61508
Part 1, 7.18 Information on the verification activities shall be collected and documented as evidence that the phase being verified has, in all respects, been satisfactorily completed.

Part 1,7.14 Documentation for validation shall include:
-Activities in chronological order
-Discrepancies between expected and actual results

 IEC 61511-1

Periodic proof test shall be conducted using a written procedure to reveal undetected faults.
TÜV
Guidelines for Safety Related Software
- All tests should be dine by an automated procedure
- Tests must be reproducible
  
 
 
Testing a Safety System software application involves various phases, as follows:
 
         • Simulate process inputs          • Verify results
         • Write input values in your safety system          • Identify discrepancies
         • Execute the application program          • Document the entire test campaign and results
         • Read safety system outputs
