[PLC pig roaster]

Hello all,

 

For my final theoretical project for my college course, I am required to build something which requires a PLC or a microcontroller.

 

I have decided to build a portable PLC controlled rotiserrie machine.

 

I haven't determined all the parts that I need for this project yet, but was wondering if someone can help me out figure out if its possible

 

I belive that the Unitronics M91 PLC wll be suitable for this project. I will have a portable 12VDC supply (Car Booster Pack) to power the PLC.

 

I require the PLC to:

 

- Set/ Operate a (stepper or geard) motor to spin the spit in a clockwise and counterclock wise direction.

- Set/ Operate a (stepper or geard) motor to raise and lower the spit.

- Measure and display 2 anolog temperature sensor readings

- Measure and display the speed from a tachogenerator

- Contain programable "set time" operations

- Contain display with time of day and other varibles.

 

Can this be done? What limitations will I encounter?

I would really appreicate some help

 

Thank you
