Hi I appreciate your help and time, I'm very new to PLC's do you have an example or any reference? Regards Rich

It's a quick question really. I'm having trouble with a particular problem. If I latch an output (motor O:2/0) with an input (start I:1/0) which then in turns unlatch by seeing another input (Prox sensor I1/:3). How can you restart the process when the start (I:1/0) is pressed again. Obviously the motor won't unlatch because of I:1/3? I'm rather confused with this one. Please see attachment. Any examples or drawings would be a great help. Regards Rich

I had to decipher some of the wording of what you said, but I would just like to say a big thank you for your help. That's one small hurdle of many to overcome! Thanks! Rich

Hi all, I'm in the early throws of learning to program Allen Bradley PLC's. I am a beginner so lamen terms will help me a lot. My program is for a door simulation, I'm sure some of you may have come across it. It's with regards to rung 2 and 4. The problem I am having is I am using a binary count to flash my output (control panel lamp) S:4/6. When the door is closing I can get the 'close' lamp to flash, but once the door is fully closed I can't get the output (closed lamp) to stay on and not flash. I feel I've tried everything. Banging my head against my desk no longer works. I will include a copy of the code, see attachment. Please try and not pick holes in it too much as its the first time I have tried this. Though constructive comments are always welcome Thankyou Rich.
