mrdegold Posted March 14, 2012 Report Share Posted March 14, 2012 Hello I am new to Unitronics OPLC's. Most of my experience has been with RS Logix programing software, The Unitronic was highly recommended to me. I really like the idea of a PLC and HMI in a single package. I decided to start working with the Jazz unit and the U90 software. I printed out the tutorial and followed it line by line. I think that gave me a good starting point for the basic layout of the U90 software and how the HMI interfaces with the logic, My first couple projects I wanted to start working on require me to interpose from 2 too 4 timers. What my definition of interposing timers (right or wrong) is timers that start / hold each other. An example of this would an aeration system where I would energize a solenoid for a short time then pauses for a short time. I am attaching an image of how I would do this in the logix software. Thanks for the help Michael Quote Link to comment Share on other sites More sharing options...
