R.Smolders Posted July 22, 2015 Report Share Posted July 22, 2015 Dear support and forum members, My name is Robin from the Netherlands, and my boss gave me the ambitious opportunity to program a seemingly easy wood-sanding machine. For this project we bought a Vision130 (V130-33-R34) The machine has: -A conveyor belt for transporting a wooden board, with frequency regulator for the speed. -A safety door lock. (Machine should only be operational when this door is locked) -4 motorized, rotating sanding brushes (2 of these brushes have frequency regulators for the speed.) -4 motorized height adjustments for the sanding rolls (with encoders). -Thermal protection. -The standard buttons like: main switch, emergency stop button, start / stop button, and also an electronic stop. As I'm completely new to ladder programming, I'm struggling with some issues already. I'm familiar to programming languages such as C#, C++, SQL and I know a little Structured Text. I need to address Memory Integers to some states of the machine (so I can 'use' the output of the last line as a condition (input) for the next line. I chose not to use a Memory Bit, so I can address multiple states. In the file that I enclosed in this post, there is the program as far as I could get it to this point. I do understand many of the logic that comes with this machine, however my background is software engineering with no knowledge of PLC's or electronic components. I find it difficult to understand some of the tutorials and manuals that I have read so far. Hopefully there is a smart guy or girl who can help me with this. Regards, Robin Schuurmachine PLC Ladder.vlp Quote Link to comment Share on other sites More sharing options...
