Hello everyone, I have a project where I'm supposed to make a machine, using the V570 (and program it with Visilogic 9.8.79 beta). This machine is required to detect the reference numbers of smth else through its RS232 port, run some tests and then print a label that the thing it tested is in a good shape ( that's just a global view about what I'm supposed to do ). Given that I only have the V570, I know that I/O ports must be added, though I'm clueless to what exactly ask for. I did some researches, and found that there are "snap-in" and "I/O expansion modules" that can be added, still I don't get the difference between them. So my questions are : - what are the Snap-In and I/O Expansion Module exactly? when and where do we use each of them? - How do I chose what should I add to my V570 ? - What hardware (other than the V570) should I exactly have for this project ? thank you in advance

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
