System Integration Testing

If the project contains functions that are dependent of more than one controller, or

other external systems, these functions shall be verified in a complete system setup,

comprising all involved sub systems.

These kinds of tests can be done in a staging area or after installation in the actual

plant.

Modification Testing

Impact Analysis

If modifications are done to hardware or software parts that already are tested, an

impact analyze shall be performed to identify all parts of the system that might be

influenced by the modification.

For application changes, the “difference report” presented after compilation (see

Difference Report on page 112) provides information that will be useful in verifying

the completeness of the impact analysis.

Functional Testing

The changed parts of the system shall be tested according to the procedures

originally used for such testing the first time. If the modification is done on a

Function Block type or Control Module type, functional re-testing shall be

performed on the instances of the type.

Regression Testing

Regression testing shall be performed to verify that no unintended effects of the

modification have occurred. Such regression testing shall cover all parts of the

system identified in the impact analysis. The level of regression testing shall be

determined based on a competent judgment of the extent and the complexity of the

performed modification.
