Update PLCs Without Revalidation

April 1, 2004
The Validatable PLC service allows companies in the pharmaceutical and other critical process industries to update their legacy systems without expensive and time-consuming revalidatation.

The service is designed for companies that want to upgrade their legacy Modicon PLC platforms to Modicon Quantum IEC-based systems that comply with FDA regulations, a validation environment, the S88 model and 21 CFR Part 11. Working through its nationwide network of authorized system integrators, the vendor’s applications team serves as project manager, assisting with the design of new systems as well as intelligent upgrades to existing systems. The team provides support to local integrators in new system architecture design and tools that allow an object-oriented approach, while helping customers through the steps dictated by the S88 model. The vendor validates the PLC code and each of the changes in order to have systems quickly ready for implementation in designated plants. The rigorous process addresses key elements implicit in preserving customers’ validated solutions.
