Good Morning, I am working on my first mildly complex program with LOGO!, I am using a 4-20 ma pressure transducer for a compressed air system, consisting of two air compressors. I call them Compressor A and Compressor B
up to this point the system works as intended, however I want to alternate the order of those compressors. I have some ideas but not a good way to actually implement this,
But how do I go about switching the order? would I just simply add a second function block ? if someone here could point me in the right direction I will greatly appreciate it. Attachmentalternating_compressors.zip (76 Downloads) |

Here is a suggestion for changing the priority every 24 hours. The suggestion is just to show you the principle of the change. Other events such as the failure of a compressor or monitoring the time the compressors need to restore the pressure (for example in the event of a leak).

Thanks for your help, I added some sort of hysteresis and a low pressure alarm to it, TDE display for pressure and time/date just for kicks. I am sure more changes will come later. I am attaching the file with the small changes I made in case someone could benefit from it EDIT 7/5/2024 Added a new attachment
