Bug free PLC programming example – 21 CFR Part 11

PLC programming example

GMP (Good Manufacturing Practice), GAMP 5 (Guide for Validation of Automated Systems), 21 CFR Part 11. IEC 25010

Best practices in the PLC programming realm, uses Static Analysis (verification testing). It is probably one of the least covered in PLC training, and therefore least practiced. (With those receiving BIN95 PLC training being an exception to that rule as they have always covered it in the instructor based classes since 1995.) Yet it should be one of the most important parts of the automation control design phases.

See 5 reasons why static analysis of PLC programming is very important.

The most important being Safety, Maintainability and Cost Savings over the life cycle of the equipment that PLC code controls. Many machine designers and system integrator claim they do not have the budget to do static analysis to GAMP 5 level of quality. The cost of not doing so, is passed on to you (the end-user of the equipment) for the life of the equipment.

That cost to end-user, when measured in using TDC (True Downtime Cost), can and often is … astronomical over the life of the equipment.
