<p>A followup. I've pretty much got everything I intended to up and running. The control box now runs the light schedule as well as a twice daily feeding schedule. A feeding cycle involves turning off the pump, waiting 3 minutes for the backflushing to end, triggering the feeder, and then waiting 6 minutes before turning the pump back on. I got the EPICS control system software running and talking modbus to the PLC, and then created a control screen and line plot. Some photos attached here.…</p>

I've started working with a nearby passive solar greenhouse project and hope to have another of these boxes up and running on a larger scale system.</p>

<p>Ah! Clever idea. It does seem the RS232 interfaced sensors come out cheaper in general, so bringing the data in through serial is another solution. I've been all focused on trying to get the 0-10V or 4-20mA signal directly into the PLC.</p>
<p>One comment: the atlas-scientific site freezes up whenever I click on anything beyond the home page, so I can't get much out of it at the moment.</p>

<p>Very good work.. just give you some more ideas. I have work with F0-CP128 Triple Port ASCII CoProcessor module! You can do fantastic thinks with this module. You can interface with a MAX232 pH stamps, EC stamps and DO stamps from <a href="http://atlas-scientific.com/">http://atlas-scientific.com/</a>. With these stamps you can make a more sophisticated system for example to measure the dissolved oxygen In your fish tank and control the air pumps more efficiently. With this card also you can…</p>

With these stamps you can make a more sophisticated system for example to measure the dissolved oxygen In your fish tank and control the air pumps more efficiently. With this card also you can interface to the PLC a serial controlled LCD screens to display data. DL06 support a small LCD with 2 lines but you can build your own LCD with 4 lines. You can also use 2 digital inputs to make up and down scroll menus to the LCD. This is very low cost solution!</p>

I have one of those as well sitting ready for a project.<br />
Throw an ECOM-100 module in that puppy nd you could have the PLC send emails even if the PC goes down :D
