Looking to Learn About Automation

I am looking for advice on where to start a self study in controls automation. I am a Water Plant Operator, and I am surrounded by controls automation. My aim is to attain a better understanding of the systems I use to interact with the Water Plant, and therefore, better communicate with the people that fix issues that I experiance. I am fairly proficient with computers, but the only programing language that I know is visual basic. I could probably learn another language but have never had the need. The user GUI that we use is from WonderWare. I am more interested in the PLC side. In the Plant I deal with Allen Bradley SLC 500, Control Logics L72, and Compact Logic 1769-L33ER.

Thanks for your help.
