I have been asked to convert the PLC on an electrostatic precipitator to something more current. I have everything I need to do the program translation. However, in the interest of exceeding the customer's expectations, I was wondering if anyone here is up to date on the current best practices in the field.
The existing program controls the plate rapping cycle, it constantly seeks the optimum voltage level for each field, and it controls fault annunciation. The system was originally installed in 1990.
This project is limited to replacing the PLC. There will not be any new mechanical components. Are there any new control techniques that have been developed over the last 16 years? If so, can anyone provide any links to where I might find information on the current state of the art.
