Posted 5 Mar 2021 Hello! I have an FX1N PLC that I want to use to operate a sprinkler system. It should have two functions. 1. 1x30 minutes of operation every day. 2. 3x10 minutes of operation every day. Thanks for the help. Share this post Link to post Share on other sites
Posted 5 Mar 2021 You'll need GX-Developer or some other programming software to write your program. 1 person likes this Share this post Link to post Share on other sites
Posted 5 Mar 2021 Hi, thank you your answer. :)I know the program and I found the time, the date registers... I just got stuck with the next steps. I don't know how to operate an output or a mercer. I tried a lot of things that can be found on the internetnet, but I was not successful. :( Share this post Link to post Share on other sites
Posted 6 Mar 2021 Ok, so you have understood the time and date registers. You now have to choose what time of day you want the actions to happen. You then put a line of 'if = ' ie You want the sprinklers to operate for the 30 minute period at 10:15 at night hour=k22 and minute=k15 SET M0 M0 run timer T0 K18000 M0 turn on Y0 (sprinkler output) T0 reset M0 Use a different M relay to turn on Y0 with each run sprinkler event Have a go at turning that in to code. 1 person likes this Share this post Link to post Share on other sites

Turns out I was lame :)Even though I typed the command correctly, it doesn't work.The problem was that I didn’t select the square brackets. :) :) Share this post Link to post Share on other sites
