I own web based software for irrigation water management called Probe Schedule. Part of the scheduling is irrigation valve scheduling and activation. The hardware actually opening the valves is the Nelson TD200 and Nelson Twig. This is an off line system but can take instructions via RS232 port. I want to put a plc between the PS and TD200. The plc will be hard wired to the TD200 (RS232) and will take the instructions and give the commands as and when needed. These commands are Valve X On or Valve Y Off. PS will generate a schedule for up to 200 valves, consisting of Valve number, time ON, duration.
This project is for someone who can program the plc to take a set of instructions from the PS ftp site and pass along to TD200. The plc could be any brand but right now I am thinking OPTO 22 Snap Pac or ABB. I have the protocol used by PS and by TD200. I also have TD200-Twig hardware to supply to the successful contractor. This project must be completed within 1 month.
I am open to using any brand plc the that programmer is comfortable with.
