Hi Guys, I have a commercial client that has asked me to program up a CTC to have 1 page that has 5 loads with an individual On & Off Button for each. When the On button is pressed, he would like it to start a stopwatch which displays the result of how long the load was on under the On button when the Off Button is pressed and the same with the off button. So when the Off button is pressed the Off stop watch starts and records the time when the On button is pressed, and so the loop goes on... As an extension to the above requirement, he also wants the data saved in a text file to be able to retrieve the data later for analysis. Has anyone got any ideas in which direction I should look at going ?
