The PLC/ Embedded Controls Debate
- Some say that using PLC code that some back
yard busnut wrote requires you to go back to the person that wrote
the code. Absolutely wrong, the fact is that
Detroit Diesel and Allison Transmission are the worst of all when it
comes to getting your expensive and proprietary DDEC or ATEC control
box fixed. Or ask the company that built the controls for your
generator or heat system to provide you with the code and see what
they say. Automotive companies can even go so far as to prevent you
from monitoring a signal from a sensor with that expensive diagnostic
tool you just purchased because they have declared that sensor signal
a proprietary trade secret.
- If you use PLC's or imbedded microprocessor
programmed in ladder logic, C, C+, Java or any other programing
standard available to anyone who wants to give it a shot, you can
chose anyone familiar with the programing language. Just stop by any
technical school and find a sharp kid to check out the problem for a
few bucks. In not so many years industrial, automotive and desktop
computers will not be distinguishable except for the color and shape
of the box.
- Most of the smart plc and micro controller
manufacturers are realizing the need to produce extended temperature
range components if they want to compleat in the next decade.
