I'm in the process of building an Electric Home Brewing based on Kal's design on http://www.theelectricbrewery.com. The major difference between his design and my design is that I'm going with PLC/HMI controls versus a control panel. I'm a chemical engineer and design and implement control systems for a living so such a project is right in my sweet spot.

For controls purposes, I've chosen a Direct Logic DL06 PLC. I've been wanting to try one of these cheap PLC's for years, so this is the perfect project to give it whirl. If I don't like it, I'm going to swap it out with an older Allen Bradley SLC500 I have laying around at work.

The other control difference I'm implementing is to use a Cascaded control loop on the Mash Tun Temperature control. The Mash Tun Temperature Control Loop will set the HLT Temperature, which in turn will control the HLT Heating element. This is a very similar setup that I use in full size industrial applications. Of course, I can always put the HLT Temperature Control Loop in Auto versus Cascade and just control HLT temperature.

Here is the panel I'm building for this brewery.


Here is the Wiring diagram:


Finally, here is the I/O wiring diagram:


Feel free to provide any tips or let me know if I overlooked something.

Unfortunately, the Blichmann Brew Kettles are on back order so it will probably be the end of April or Early May before I get this project complete.

The last thing I'm working on is picking out the HMI. I'm thinking about a panel mounted HMI, but may also just put the software on a laptop powered by the external outlet on the side of the cabinet. This way, I have a programming node/HMI on the same PC.

Thanks in advance for any feedback.

Its unfortunate that there isn't a "personal License" or something similar from Rockwell. But then again, Rockwell is a bargain compared to Emerson's DeltaV Licensing. Even as one of only 50 Rockwell Solution Partners here in North America, we pay $$$$ for licensing.

Thanks for the heads up on the Polar Pots I'll check them out.

Subscribed! I'm interested in seeing the outcome.

Sweet. I was going to roll my own but I have to check this out before doing so. I have licenses for Wonderware, FactoryTalk, iFIX and about a half dozen other HMI products but my goal is not to have to use any of the high $$$$ HMI software to avoid having to buy a license that is not work related.

Here is the panel so far


I'm still waiting on some parts.

Also I decided to switch out the 10 gallon kettles for 20 gallon Blichmann kettles. I figure if I'm going though th effort of doing this I might as well set myself up for 10 gallon batches.

Here is my in progress SLC5/03. I'm just using my turkey fryer setup because I'm kinda in the middle of getting the house ready to sell and build.


Here is my old version of Advance HMI project.


I choose it over RSView because of the ease of using the source code of Advance HMI. It is very easy and very versatile.

Nice. If the DL06 didn't work out I was going to swap it out for a SLC. However it looks like the DL06 will do just fine.

I have a DL06 in my drag car that I use for data logging and the dual stage nitrous control. For the price you can't beat them. I also have rs logic 500 on unlimited installs if I were to use a micrologix 1500. Which can be found used on eBay. This may be an interesting thread.
