Questions About Movicon 11 SCADA and Movicon.Next SCADA
I would like to start a thread for Movicon 11 SCADA and Movicon Next for solving basic problems. So you can write your question(s) below into the "comment" side and then I(or anyone who want) will try to give the answer your question. We, as the learner of the Movicon, are waiting your questions and contributions.

Do you know how to write such a code in the Movicon in Basic Scripts so that you can track the appearance of a signal along the previous edge of a variable, and also changes in the signal along the falling edge?
ReplyDeleteIn the first sight, your question can be solved with two properties of the Movicon, which first one (as you said) is "Basic Scripts" and the second one is related to "How to execute this script?". It can be named as "Events". So we will focus onto the two concepts: "Basic Scripts" and "Events". Steps can listed like that:
Delete1-) Create the variables. One bit for signal and two words for counting the number of occurrence.
2-) Right click onto the Event and the click "Add a New Event Object". You can change the name of the event.
3-) In the created object;
Event Variable: Name of the Bit(Signal)
Condition: Change
Commands: Choose the script that you want to execute
4-)Add a new basic script and write below basic code:
If Signal = False Then
NumberOfZero = NumberOfZero + 1
Else
NumberOfOne = NumberOfOne + 1
End If
In addition to that you can track the time of the being false and being true in the same time. I mean how many minutes this signal is gone high or low. You should use for the second variable of the System Event. Every change of the signal you execute a script that count the number of total seconds.
I hope my answer fits your question.

I still do not understand how to use Basic Scripts to track the change in the signal along the edges. At the moment, I have implemented tracking the signal edges using Events for changing this signal. But based on the fact that I have a lot of such bit signals, it is necessary to write a universal handler using Basic Scripts, but I don’t understand how to describe the change in the bit signal in the script. I plan to run the script every 125 ms cyclically
DeleteIn that cycle time, it looks good idea to use ladder diagram of PLC which can asset this cycle time(scanning time of PLC).
Deleteis it possible to drag pen in trend area to visible as we drag that pan (variable) on trend area and show that historical data as well as current live data?
ReplyDeleteThanks in advance
Hi,
DeleteYes you can. When you connect data logger to the trend you can easily edit the pens. Under the properties of Trend, you can make visible pens under "LEGEND AREA". In this area, there are many things to personalize. In the run time you can see trend which variable(s) selected. On the other hand, with double click on the pen you can change the properties of the pen in the run time.
Best Regards...
