Hi, I am very new to PLC and am using this site as a tutorial. I read just about page on this site and am now using the sites simulator for the first time. Heres my question/problem.
When running the simulator I start with a NO contact on the left rung and an NO coil on the right. For the contact I address it as I/0 or I/1 and for the coil I address it as O/0 or O/1. I then run a scan and nothing happens. I clicked the help tab and I am doing exactly as was done in the example used in the help section. I tried using NC contact/coil and the display would energize when scanned but my Input and Output address' would turn to ?. Im not sure what I am doing wrong. Im guessing somehow Im using an incorrect address although Im using the same ones as in the help section. Any information would be appreciated.
