Aram, I think I mentioned 25 rungs. I think you can go well beyond 25 rungs in the LCNC version. I was comparing a stand alone hard PLC - like the Rockwell SLC series to the LCNC soft PLC and what I consider to be "practical". If you just want some PLC functionality, you should consider the Automation Direct Click PLC's. They start at $69 and have a Modbus RTU interface which I have linked with LinuxCNC via ClassicLadder - Modbus. If you forget that the Click PLC is actually a PLC, and only consider it as Modbus I/O, I don't think you will be able to find cheaper Modbus I/O.
