I thought I would add an about me. I am a simple man, with simple likes. I develop polyurethane foams and gels by day and raise beef cattle by night. I have been having a blast with the Unitronics PLC's. From controlling temperatures, tank weights and levels in the tank farms to upgrading old test equipment. I owe a big thanks to our Unitronics distributor, The Proud Company. They have been great with supporting us.
