Prior to development of PLC/HMI code, Haskell works with their clients to develop the foundational documentation which defines the user and software requirements. This work typically progresses through the development of the functional requirements, recipe parameters, sequence charts, and software design specifications.
After agreement on the technical content of these documents, the PLC and HMI programming code is developed. After development and prior to installation at the client's job site, we thoroughly test and document PLC/HMI programming performance. The Software Test Protocols and Site Acceptance Test Documents are developed based on criteria and requirements defined in the foundation programming requirements and specifications.
We believe in providing proper documentation with the code we write, so that the control system can be maintained and understood by your plant personnel. Haskell engineers focus on developing well-structured and easily maintained logic that provides the flexibility your facility needs today and in the future.
Haskell is proficient with the most modern PLC technology. We continue to provide quality support for legacy systems that many System Integrators cannot manage. Haskell will work with you to get the most out of your plant's capital investment in controls.
