Luckily I can build executables that run without a full LV installation on the brewery PC.

I actually changed a lot of the plumbing around in my basement because: 1. needed to run a drain and a couple water lines to the brewing room, 2. old plumbing was not that great. Tomorrow I will be finishing up the plumbing to the sink. I was lucky the storage room I am turning into the brewing room was near both my laundry room and my main electrical panel.


That is actually a picture of my old sump pump which was in drastic need of replacement. Yesterday I installed a new fully submerged pump and cover.


I don't plan on using the sump as a drain unless I am washing the floor or have any major spills.

It all depends, you usually can get the rack and power supply under 100$. The processor depending on the version can be 50-100+. Your regular input output cards are cheap, anything analog will drastically jump up. The biggest expense will be the program for the plc, logix 500. RSLogix 500 starter is around 500$ and RSLogix Standard is around 1200$ and Professional is 2000+.

Yea, but ebay can be your friend.

You can find the software there and pretty much anything you need to get going.

The PC will communicate with a microcontroller board I am building to provide all of the low-level system interfaces such as switch inputs, SSR PWM, sensor reading, etc.
tell me more about this microcontroller board you mentioned. I am trying to get away from allen bradley equipment and move to cheap computers and java.

You can build your own microcontroller pretty cheap, Im not sure what the OP is doing, but arduino is a nice and cheap platform to go with. I believe the programming language is C++(not sure that site should let you know, they might have their own).

For this project I decided to try out a newer development kit that uses an Arm Cortex-M3 32bit mcu. I purchased the LPC1768 version for around $25. Shortly after the purchase NXP had a contest and a survey to fill out which netted me two free LPC1114 Cortex-M0 boards Might use one of those for a keezer/fermentation temp controller. These are overkill for what I need them to do but it is always fun to learn something new.

The demo board has two halves, the first is a JTAG debugger/programmer the second is the "target" or microcontroller. It is programmed in C with all the software needed to create basic programs included.


I will be creating my own base circuit board that the LPCXpresso board will mount to inside my HMI. The base board will break out any peripherals or signals I need and mate them to proper connectors.

I already have the code in place for three channel PWM control of my SSRs after reading in a value from the front panel potentiometers while in manual or hand mode. Last week I finally got the 1-wire master code working so I can read in temperatures from my DS18B20 digital temp sensors. Still a lot more work to be done with this.
