Hello everybody!

I want to implement the following features in my project:

1. Operator is able to program a scheduled maintenance work for a motor. 

2. System alerts the operator one day before the scheduled date is due, through the alarm control, and the operator is able to acknowledge this alarm/alert. 

Feature number 1 is kind of already implemented. The missing feature is number 2. I have an idea of how to implement it but it deals with database communication and other stuff. 

What I want to ask you is: 

Is there any option that directly implements scheduled alarms in TIA Portal? Let's say program an alarm to be triggered at certain date and time. 

Also, I am only using a PC-based system. I am not using any controller inside my projet.

I read about "Program alarm" blocks, but I didn't see a way to implement scheduled alarms with it.  Also, by the limitations of my project I can not add a controller device to it, so I can't use that block.

Furthermore, I came accross with "WinCC/Calendar Scheduler and WinCC/Event Notifier" (https://support.industry.siemens.com/cs/ww/en/view/60532594) and for what I have seen it might allow me to implement the scheduled alarms that I am looking for. I don't really know, I am not sure either if I can install it and get it work along with my winCC Unified installation. 

Any suggestion is very much appreciated. Thanks in advance. 

The installed software in which I am currentlly working on, is:

- TIA Portal V16 Update 4.

- STEP 7 Professional. V16 Update 4.

- WinCC Advanced / Unified PC V16 Update 4.

Hello Alex,

i do understand your intentions and i don't know if there is an easy solution. At the Moment i can think of 2.

1. You need an internal tag for the alarm and you need an internal tag that saves the date of the next scheduled stop. Now you need a cyclic script that checks if the current time is bigger than the scheduled date - 1day. Since your script does not need to be triggered every second a cyclic trigger every minute should be enough an not use that much of ressourcces. You need to think of a way to clear that the alarm is raised every minute if you already aknowledged. Maybe with another internal tag.

2. There indeed is an option named Calendar. There you can define those maintenance intervals and define events that should be triggered a specific time before. I would recommend getting in touch with your Siemens contact to get a little more information here. Because it needs to be based on the technological hierarchie.

Best regards.

First of all, thanks ZickZackTIA!

And sorry for the late response. I have managed to get this correctly working with the help of database handling as I was thinking before. However your suggestion is also a great idea!

Now I am checking the performance of the project and verifying the resource consumption. 

Thanks again for your response, have a great day!
