Also, I was just told that instead of the 4 hour wait, to just keep it as:
Turns on for 30 seconds, then off for 2 minutes. Cycles 5 times then stops.
This can also all be avoided if someone manually presses the reset button i setup on the HMI.
Thanks

Sounds like a fun project. Is this a classroom exercise? Regardless, take your best shot at it and post your project here. Someone will be happy to assist.
I am an intern setting up a wireless doorbell. I have everything setup and as of right now in another function, I have it turning on for 5 seconds then off but that is it (it also keeps a log on the HMI for which push button is pressed and the date/times it was pressed). I just want to improve on the project.

Hello, I am a beginner and am having trouble completing this task.
I am trying to turn outputs on from a push button for about 30 seconds, then off for 2 minutes, then on again for 30 seconds. Repeat 5 times. After the 5th time, I would like to increase the off to 4 hours. This happens until someone manually presses the reset button on the HMI.
Any help would be appreciated. Thanks

Hello, I am quite new at PLC's in general. I am using Banners DXM 100 to communicate with a Push button, which in turn all talks to the PLC.
I am having trouble navigating on how to connect the DXM using UniLogics software. The PLC is already connected via Ethernet to the DXM.
Any help would be appreciated. Thanks

Can you explain exactly how to index the data table down a line each time?

Hello, I am attempting to create a system in which every time someone rings the wireless door bell, it communicates with the PLC and keeps a log of the time and date at which the button was pressed. I am almost done, and only need assistance when indexing down a row (copying the data from the previous row and writing it to the next). I see there is a indexing row tab on the button, but i need help understanding the function in and out tabs and how to use them successfully within my program.
Any help would be appreciated.
Thanks, Michael

Thank you, this information helped out a lot. One last question, when doing the call functions, I see you numbers the time to #1 and the date to #9.... are those arbitrary numbers? What do they represent?

So I am a beginner when it comes to not only unitronics software, but PLC's in general. I am tasked to connect 2 door bells (one in the front, one in the back) to the PLC and create a program that once one of the buttons has been pressed, it sends a signal to the plc which activates a horn and tower lights (depending on the door).
My problem is creating a data table that acts as a log. It is supposed to keep track of - 1. the time when a button is press, and - 2. the date.
Also one other question, the timer off command doesn't seem to work in my programming, which is supposed to turn off the outputs after 5 seconds. of being activated,
Thanks, I know it is a lot but any help would be appreciated.
Ladder counters
in UniLogic Software
Posted
Hello, I noticed that the Unilogic software doesn't provide counters like other software's do. I am having trouble getting out of a loop pulse timer. I am trying to get out after it loops 5 times through. Any ideas?
