Hello,
Before I make my inquiry, allow me to introduce the setting of my question... I am doing a senior project with PLC for college. I am also interested in PLC and automation so this project is a hobby as much as it is a "project".
I am not a complete noob with PLC. I have some experience in school. I understand basic electrical and how to write basic ladder logic. But I am having an incredibly frustrating issue...
First, I havent bought the PLC, but I dont need anything too over the top. I plan to go with a CLICK PLC from Automation Direct with an I/O expansion. All discrete outputs.
The software I am using to write the ladder logic is "LogixPro" - a cheap PLC programming simulator.
So, onto the question. I keep getting a timer loop. Basically, what I am trying to do is turn an output off that is ON in a previous rung, with an output from a timer later in the logic. And no matter what I do, I keep getting a loop. Even when I use a fake output after the last timer, which is turned on by the done bit, to shut off the previous rung output with a NC contact, it still loops.
I have attached a picture of what I am speaking too. If any more information is required, please let me know.
Thank you all
