Here's the part where I wish people actually read this and commented on it. My questions today or even all this week is working with PLC's still considered Electrical Engineering or is it Technician level stuff?
I attended a class taught by a technician. Kohler hired technicians and engineers but the technician got to do all the cool stuff which irked most of the engineers.
Every year they seem to get easier to program and the jobs just seem to be simpler and more routine. Everyone at UWM seems to think they are for techs and not engineers but they seem to want to hire engineers to do this stuff in industry. Nobody seems to want to hire me to do anything else anyways. I suppose PLC's with the ability to advance to something else would be nice but I do not see that happening at places like Oilgear where they have a routine way of doing things and just crank out projects left and right.
If only I had a choice *sigh* .....
Let's look at some points and lay it all out and compare it to Say VHDL code
They both create logic. PLC logic goes into a big box that outputs 24 volts DC. PLC's do the same with 24 Volts. PLC's can have analog signals VHDL needs a DAC which creates a binary number normally around 16 bits long. (Not sure if PLC's can do this)
Result: Tie
VHDL chips need to interface with chips and cannont directly store their programs in memory. They are placed on PCB boards and require all sorts of power circuits and buss circuits. PLC's are just one big box a tech can program but a tech cannot get the PCB layouts and the other circuitry correct without an enginer.
Result VHDL has this one.
Both are used in a variety of equipment though PLC's are constrained to industry.
Both have some sort of language although VHDL is a much more elegant language and is more powerful
I guess it all boils down to what you like better.
