IoT & Connectivity

Hello All,   Last weekend Brazil should have entered Daylight Savings Time but it was canceled earlier this year by the government. After that, some services that use times are very strange.   For instance, this simple javascript code that returns the epoch timestamp: time = new Date ("2019","09","25","0","0","0");time_ms = time.valueOf(); result = time_ms;   This returns the following result: 1571968800000.  Converting this epoch value to date time using https://www.epochconverter.com/ gives the following date-time:  Thursday, October 24, 2019, 11:00:00 PM GMT-03:00 which is offset in 1 hour from the time inserted originally.   Using the same code on an online javascript editor such as https://playcode.io/ gives the result 1571972400000 which gives the correct date.   The time on the client-side and the server-side are correct.    Any thoughts?

I created a chart mashup application using the Time Series Chart widget.  Currently I am querying data inside the mashup containing the chart widget and feeding it into the chart.  Some of my use cases may need the data queried or filtered differently, so it may be more useful to pass in the InfoTable of data into the mashup as a parameter.   My question is whether it would be feasible to pass in the 16 InfoTables of data (max pens for Time Series Chart widget) with potentially 100s or 1000s of data points each?  Are InfoTables passed into Services and Mashups by reference or by value?  Or in other terms, Is a local copy of the InfoTable created when passed into a Service or  as a Mashup parameter? This information will help determine memory usage and effects.

Hi, hoping someone might have a solution to a problem we are having when applying the license bin file on startup for a linux server. It looks like it gets the license file, but fails to start up. We are running the start up as root to test.  Below is the errors we see in the application log 2019-11-04 19:48:00.571+0000 [L: INFO] [O: c.t.s.s.Subsystem] [I: ] [U: SuperUser] [S: ] [T: localhost-startStop-1] Starting Subsystem [LicensingSubsystem] 2019-11-04 19:48:10.421+0000 [L: WARN] [O: o.a.h.c.p.ResponseProcessCookies] [I: ] [U: SuperUser] [S: ] [T: localhost-startStop-1] Invalid cookie header: "Set-Cookie: visid_incap_1771292=fQXYN9JSTxC+vZ2H074m93mAwF0AAAAAQUIPAAAAAACIdU6MhoTtktTrSVr45uS5; expires=Tue, 03 Nov 2020 10:54:13 GMT; path=/; Domain=.ptc.com".

Hi, I am using ThingWorx 8.2 and suddenly the license got ignored. I generated a new license for my device id and deployed it again. But it ignored the license again. Please help me to resolve this issue.   Thanks, Shalini V.

Hello Experts,   Good Evening...!  I am looking for a method to link the Chart widget or another mashup to the values/parameters available in the Advance Grid containing info table data. Want your suggestions how I should get it done. FYI I am at beginner level about TWx platform

We have an old version that we cant get up and running again.Version 7.4 running on Ubuntu 14TLSI'm now trying to build a new server and restoring/moving data from old to new.Steps I've taken:Have a new server CentOs 7 with Postgres. Thingworx 8.4.2 installed and working. Can login to Thingworx composer etc.I then copy the folders related to Thingworx from the old server to the new. I also export the data out the old server with pgdumpOn the new server I recreate the DB with the scripts provided in the install directory. I then import the pg dump file into the new server.When I start tomcat I cant access the website.Error:503 Service UnavailableBack to composer.

Good afternoon,   I recently connected Thingworx to a remote OPC server via the OPC Aggregator. The connection was made successfully and all of my devices are populated as Things in Thingworx. Within the Thingworx Composer I can browse all tags normally via any Mange Bindings screen. However, when I try to browse for tags in either the Trends & Troubleshooting or Configuration & Setup, I cannot expand past the top level. Why would I be able to browse for tags in Composer but not from within any of these mashups? See attached screenshots for the differences.  

Hi guys,   I am trying to figure out how to customize the KPI calculations on a shape level and not equipment level.  Is this possible?    For instance in my system quality is always 100%.  I tried changing the QualityRatio_Calculate service on the PTC.SCA.SCO.QualityRatioThingShape thing shape but that is not possible.  Where can I set this then because it has to be true for all assets.   Any assistance is welcome.

Hi All,   I want to create website like menu similar to screenshot below using thingworx mashup. I had tried creating the same using thingworx widget like (tabs). But the look and feel of the mashup created using widgets is not the same.Please let me know if there is any other widget which I can use or I need to create a custom widget or any other approach which I should follow.

Hi,   We can create and set remote binding programmatically. But how can we set property attributes such as "Start Type", "Cache Method" and other parameters related to remote property.   I have attached the image for better understanding.   Also, I have shared the code which I tried.       With regards Yedukrishnan   var aspects = {"industrialDataType": "Short","tagAddress": "Channel1.Device1.tag3","scanRate": 1000,"tagType": "Static","readOnly": "true"};   var params = {propertyName: "PropertyTag" /* STRING */,pushThreshold: 0 /* NUMBER */,aspects: aspects /* JSON */,foldType: undefined /* STRING */,sourcePropertyName: undefined /* STRING */,timeout: 0 /* INTEGER */,pushType: "VALUE" /* STRING */,cacheTime: undefined /* INTEGER */}; // no returnme.SetRemotePropertyBinding(params);   With regards Yedukrishnan  

Hi,   Can anyone please tell me how to pass selected data from thingworx collections to another mashup or widget.. Thank you in advance 🙂  

Hello,I'm in need to raise events (ThingworxEvent) from my extension. They are triggered from separate threads. My question is: what is preferred security-context: super-user (via SecurityContext.createSuperUserContext()), system-user (via SecurityContext.createSystemUserContext()) or something different? Is there a general rule?Regards,Marcus

Hey folks,    since I'm pretty new to the Thingworkx development stuff, I wanted to ask you for help. I created a data table mashup by using the standard templates, etc.    Now I want to add data to that mashup by using Postman (e.g. accessing the "Add/Update" button without using the Thingwork Dev Portal) and I don't really know how to access the mashup since it doesn't open up in a new tab. I hope you can help me a bit since I don't really know how to proceed for now....   Thanks in advance.   Here I have a screenshot of the data table so you can maybe imagine better what I really want to do:  

Hello,I am just a beginner of the ThingWorx platform. Does thingworx provide any facility to send alert messages via SMS or email? If yes then how?

Has anyone implemented ThingWorx Asset Adviser? I would like to know what data points did you collect from your machines? What roadblocks or issues you ran into while you were implementing predictive maintenance? I would love to connect and see if you can share some of your experience that can help me avoid mistakes that everyone makes during predictive maintenance implementation?   Thank you in advance for the help!

I’m trying to see if a KEPServerEX server can read some points from a Oracle database and then write them to a Wonderware Historian.   I found the Kepware client connectivity guide and it sounds like you can have a KEPServerEX write to a Wonderware Historian.   Can it write to more than one Wonderware Historian at the same time? Can it do store and forward for a Historian that is down for a time? Can it force write values that have not changes for a time? After a certain amount of time the Wonderware Historian will reply with a null value if the value has not changed or been undated with a new date time stamp.   https://www.kepware.com/getattachment/b024c169-24a5-4708-80e8-8ccb7c4d2106/kepserverex-wonderware-historian-guide.pdf
