studies I learned a lot about Governors. (Regulators) Governing is my
specialty. I do also controls for sequencing, process, auxiliaries and
protection, which in my opinion is not so challenging as the governors.
are all different and the user friendliness is depending on application
engineers who build them. When more engineers work on the same
application, the amount of mistakes and double logic is increasing. The
best applications are made by formerly field Engineers!
There must be
a good co-operation between the Control and the HMI. The HMI is a good
tool to find issues in the control logic. A modbus address can guide me
to the correct place in the logic without studying the whole program.
engineering work on site is mainly correcting mistakes, improvements
and add additional logic. I have been on sites though were I had to
build a control application and the HMI from scratch. If I have
the manuals and the tools, I can do it!
I have made
logic with Relays, Pneumatics, PLC’s and DCS systems.
