Automation Systems Integrators
Systems Integrators are companies that build and program the automation systems
They are sometimes part of the makers of the DCS and PLC systems themselves or more typically separate companies
A Control Systems Integrator:
Must understand the User Requirements
Determines an appropriate collection of hardware that can run the software required
Designs the physical equipment to house this hardware such as cabinets for controllers, inter-connecting wiring, power supplies
Designs an overall software architecture
Determines the software modules that are needed including standard 'library' modules and custom ones
Configures the module by providing all the data they need
Codes custom modules in the systems languages
Ensures that the end user is involved and ultimately accepts the system as meeting the finally agreed requirements
Provides an accurate documented history of the development of the system and the origin of the data used
And does all this in a planned time and at a cost that is acceptable for all.
