No worries, Sorry about that you are right, that was a node.js code snippet not JSON. And yes those codes are also very common. In v3 of the REST api we are going to put some effort into making the Swagger output accurate AND useful...

Thank you - the ui settings works.

Yes, I can browse and connect to OPC DA servers installed locally using other clients such as by Matrikon etc. There is very little DCOM configuration needed when you are connecting to servers installed on local machine. As I mentioned, typically browsing locally installed OPC servers should not require any username or password. The help documentation for OPC DA data source does not give a proper example of how to browse and connect to an OPC DA Server.

Is there a video that explains how it works, similar to the video for SVG graphics?

@zhilin-chen said in Why this kind of <style> can not work?: @thomaseinasto said in Why this kind of <style> can not work?: !important Yes!! It finally works!!! Thank you so much!! Be careful using !important everywhere, it makes it hard to override elsewhere. Follow my instructions above and read this article - https://developer.mozilla.org/en-US/docs/Web/CSS/Specificity

I know something like this can create a ball to move along the path. </ma-svg> </div> <style type="text/css" > .ball { width: 15px; height: 5px; background-color: red; border-radius: 50%; offset-path: path('M10 80 Q 77.5 10, 145 80 T 280 80'); offset-distance: 0%; animation: red-ball 2s linear alternate infinite; } @keyframes red-ball { from { offset-distance: 0%; } to { offset-distance: 100%; } } </style> <path fill="transparent" stroke="#888888" stroke-width="1" d="M10 80 Q 77.5 10, 145 80 T 280 80" class="path"></path> </svg> <div class="ball"></div> But what if I want to let the ball move along a path in my SVG (the path is complicated can not write it out as a single Line coordinates)? And this is what the line looks like.! [image: x8JslV1.png]

Thanks. New version solved issue.

@PSpivey can't guarantee this but try updating your Java JDK - https://help.infiniteautomation.com/installing-java The one you are using is quite old.

@uelojazz We do not currently support those protocols as data sources. However a quick Google shows IEC 62056-21 can be ASCII based so you may be able to use a script to read/write to the serial port and gather data from a meter. Another option would be to create a data source module for Mango in Java, or if you contact support@infiniteautomation.com we might be able to provide a solution. The easiest method would be to use something like a Modbus protocol converter device.

@Balistar that isn't enough information to go on. Can you review your logs from the upgrade and see if anything went wrong? Each time Mango starts it should create a new log file so I would start by reviewing the log from the time you started and did the upgrade. Also check the com.serotonin.m2m2.db.upgrade.UpgradeXX.logs to see if any SQL commands failed that were not logged in the normal log file. Thanks.

@Xof1986 that is expected. The events system uses the concept of 'user events'. When an event is raised every user that has permission to see the event gets their own user event stored in the database. This is not ideal but was used so that a single user could silence an event for themselves and not effect anyone else. To make a long story short, old events will not be visible to a new user because they will not have any user events for events that happened before they existed. We are planning to remove this for Mango 4.0 but this is how it works currently.

@terrypacker Just updated the module and saw that you added the filename regex, thanks so much!

@Phillip-Weeks just a little more info would be helpful for me to pinpoint the Mango code in question. Are you using NoSQL? What is this script from? Context point in a script? Where is the script? Meta point, Excel Report... I did a quick check of our database queries and they are correct. I can't see the data you are referring to in the image as that is only a window for times that are not in your test. Also its nice to put a code block around code as it makes it easier to read. Thanks.

@dcitech Great!

Hi Andrew I have run into the same issue before, unfortunately, there is no easy way to trigger the generated history. The generate history can be triggered by via the rest API, so you could create a script that monitors the mango PTCP data source, stores the timestamp when it disconnects, then when reconnected, do an API request to start the generate history with the saved time stamp and the reconnected time stamp. I did not have to go this far when I ran into this issue so I have not attempted the script yet.

Thanks Might add point through API from external prog as well (example phyton)
