Thank you all for your input. You have definitely given me alot to think about and several avenues to pursue. Again, I very much appreciate the responses.

Hello, this is my first post. I hope you all will be able to point me in the right direction. I am in the process of building a piece of machinery that will be exposed to the elements, will create vibration due to the diesel engine powering the machine and the shock produced by the machines processes. The machine will be moved from site to site, so I would like for the controller and circuitry to be contained on the machine. The voltage for the controller, inputs, and outputs will need to be 12 VDC. Estimated operating temp range will be -20 to 100 F. I should be able to control the machine with 15 inputs and 15 outputs. So, my question is, which PLC would work the best for my application? Also, this is my first time using a PLC so ease of learning and user friendliness is important. Any suggestions will be greatly appreciated.
