Lets make some assumptions here: 8 sparks per revolution The processor takes 20 (just a number I picked for computation sake) clock cycles to do the processing for each spark. First calculate the revolutions per second: revolutions revolutions 1 minute 60 seconds Next calculate the clock cycles per second required as 8 sparks revolutions 20 clockcycles required clock speed Hz revolution second spark (cycles/second) Does the clock speed fall into the realm of microcontrollers (10's of MHz) or microprocessors (~Ghz)? second minute PLCs how do they fit into this? Many of you have taken PLC classes and ask how do PLCs fit into the picture? A PLC's - how do they fit into this? Many of you have taken PLC classes and ask how do PLCs fit into the picture? A functional diagram of a PLC system as shown below is equivalent to what a microcontroller does. The hardware is usually optimized for ruggedness to operate on the factory floor and to use the specialized programing environment of PLCs. Depending on the requirements of a PLC, the underlying processor may either by a microcontroller, a microprocessor, or some specialized processor arrangement.

Just as an example let's assume each battle requires 100 lines of PLC code with each line taking a processor cycle. 1. Converts bottles per minute to bottles per minute 1 minute second 60 seconds 2. Calculate cycles per second cycles bottles 100 lines code processor = 1 cycle X scond Second bottle line of code Your answer should come out well within the range that a microcontroller running at 20MHz can handle. However, note that PLCS may do a lot more, for example handling high speed Ethernet communications so some have processors closer to the X
