Thanks for the input everyone, as you can tell I really spared no expend in the brewery build, I am a welder/pipefitter in the food industry, I have been around the allen bradley controls forever but will be the first to admit dont know a damn thing abput the programing, thus the interest. I hnow the piping, where the rtds go the level sensors flow meters etc, I am looking at this as another learning adventure, I worked on hot tubs 20 plus years ago when it was all mechanical relays hi limit switches etc i am going to make the process this way first (since I know how) and when thats done look at automation with the plc, what are the real software costs of the allen bradley? and thae anual costs? And a model number for the baddest ass automation direct plc thanks again so much!!
