“The Modbus training class was very informative. It gave me the knowledge and confidence to get my project going. Texas Automation Systems even provided some tools for use in the classroom that I got to keep. I was able to use these tools to bench test my project and then get it implemented in the field. The instructor was very knowledgeable and easy to understand. I enjoyed the class and learned a lot from it.” – Tony Garcia – Valero Energy

“It was a great class. It helped us to understand some of our PLC com’s issues that we were experiencing. For the price, material, and the software it was a great value that should help any industry that uses Modbus.” James Watt – Holly Refining
