I have a requirement to add a thin banner to the top of the browser window in Composer.  I'm essentially asking for the same thing as this older post that had no response: https://community.ptc.com/t5/ThingWorx-Developers/Custom-banner-in-Composer/td-p/540405  Is it possible to configure ThingWorx/Tomcat to display such a banner across all webpages served to users, including Composer?

Does a stream entry timestamp represent the moment of AddStreamEntry service execution or the moment the stream entry is processed ?

We have many channels and want to organize the channels in folder without affecting the Item ID for the associated tags.For example here, I want to have the ability to make a folder for the dryers and the PRD devices.The folder is merely for organizing within Kepware and should not affect the other systems. Therefore the Item ID, e.g. PRD0147.myDevice.myTag, should not contain the folder. 

  Hi everyone,I’m currently working on a use case in ThingWorx and would appreciate some guidance.Use case: We have a FileRepository (connected to a File Share) where we store images. A customer wants to send 6 images via REST API, each around 25 MB. Total payload per request would be roughly 130–150 MB. After receiving the images, I need to: Store them in the FileRepository Save the path in a DataTable for later access Challenge: Sending images as Base64 in JSON would significantly increase payload size (~30% overhead). The customer prefers to send all images in a single request, not one by one. I’m unsure about the best approach in ThingWorx for handling such large payloads reliably (timeouts, limits, performance, etc.). Questions: What is the recommended approach for handling multiple large file uploads in ThingWorx via REST? Is it better to: Accept a ZIP file (Base64) and extract it server-side? Use multipart/form-data (if supported properly)? Or en

I working on one of my projects. As per my application, I want to take data from DCS over TCP/IP into kepware. From kepware i want to publish those data over opc da for other SCADA/DCS that works as opc da client. My quetion is does kepware works as OPC DA server for this application?

I have a requirement for taking IEC61850 data from an IED device into the Kepserver. After which i need Factorytalk view SE using OPC UA client to read that data. How can I go about it?

We have a Mariocotta slitter HMI/Industrial PC. The mSATA hard drive failed on the PC. We replaced the drive with a new one, & restored that drive from an old Veeam backup of the system. When we restored it, the Kepware Allen Bradley perpetual license was missing. We have been unable to apply the license on the new drive. We are currently utilizing the emergency 7 day license. What is the normal procedure in this scenario? Our vendor is telling us we will need to buy a new license, but this looks like it could simply be rehosted since the only thing to change was the HDD (PC is the same PC). 

In KB article entitled- Request Information to Enable Advanced Model Target Generation directs us to find the Expereince Service ID.  I have looked on both the hosting Vuforia server and the ThingWorx server for the log mentioned in the article.  I have looked in all the relavant thignworx logs I could find, yet could not find the IDAny other ways to find the Experience Server ID?

Hi Folks, I have a thingworx 9.3 version running with basic auth (username/password) and want to implement some modern authentication for my SMTP/Mail notifications. Can anyone guide if its possible to have an advanced authentiction in place like -XOAUTH2 or OAuth 2.0 -Exchange SMTP Relay-Microsoft Graph

I am trying to configure a grid widget to editable via a dropdown list in one or more columns.I have reviewed the documentation here and here. Both documents that detail JSON configuration and dropdown lists indicate statically defining the dropdown list selections in the JSON configuration directly (ie"dropdownConfiguration": {"items": ["Active", "Parked", "Undergoing Maintenance"]}Due to the potential size and expected change over time for the list of selections I would like to define the dropdown list via a service rather than statically defined in the JSON configuration.I would appreciate some guidance on how to define a data source to be used for the dropdown list 

We have ThingWorx 10.1.0-b47.  It appears that the "Service editor theme" in User Preferences is not working.  I believe it was still working as expected before we upgraded as I utilized the "Dark" theme.  Now it appears to use "Light" no matter which setting I select. Can anyone else confirm this behavior in TW 10.1?

Hello,I’m having an issue where I create a Mashup, add a dashboard widget, view mashup, and create dashboard then the dashboard shows up in the DefaultProject. Is there a way to change this behavior?ThingWorx Version: ThingWorx 10.1.0 

Hi all,A few years back I had a use case where I wanted to use the kepware configuration API to create and modify advanced tags from thingworx. Does anyone know if this functionality has been added or is in the future plans to be developed?

Hi, I have a unique use case, where I need to shift the Focus of one Text Field to another Text Field when pressed on ‘Enter’ Key. Is there a way around based on CSS. Thanks.

Hi Community,I am a beginner in ThingWorx and trying to understand the correct way to implement custom JavaScript-based functionality in a mashup.My requirement is drag and drop. For example, I have two columns, A and B, and I want to drag an image from column A and drop it into column B. As soon as the image is dropped, I want to call a ThingWorx serviceI have a few beginner questions:For this kind of requirement, should I create a custom widget / extension, or is there any simpler way to do it in a mashup?If I need a custom widget, should I build it using plain JavaScript or TypeScript?Does ThingWorx support this kind of drag-and-drop behavior out of the box, or does it need to be implemented as a custom extension/widget? If a custom widget is the right approach, are there any beginner-friendly examples or documentation for creating ThingWorx web components/widgets? PTC’s Web Component SDK docs mention creating widget extensions and packaging web components for Mashup Builder. ()Afte

Hello,I'm reading data from another application via an OPC UA Client on any channel in Kepware. I can receive notifications when the data changes. Is there a way to create notifications before the data changes? Reading at intervals doesn't solve my problem. I have a timestamp indicating when a value has been read. I want to notify the client of the same value when the timestamp changes. 

Hello all,I use Schedule chart and I want to find a way how to expand/collapse several or all groups at the same time.Now, by default, it is possible to expand only one group (if I click on another group, the first one collapses).For example, if I click on LABEL-1 group, the detail opens, but if I click on LABEL-2 group, the detail opens for LABEL-2 group (while the detail for LABEL-1 group collapses). Please, find screenshots Is it possible to expand/collapse all or several groups at the same time?  

Hi,How can we establish an SSO connection between Thingworx and Codebeamer? Thank you!

Hello PTC Community,I would like to confirm the expected behavior of the Kepware _System._NoError tag when it is referenced from ThingWorx.I reviewed the following support article:CS466164NoError tag value fails to update in ThingWorx when NoError tag is updating in Kepware Modified: 19-Mar-2026 / Last Seen: 15-Apr-2026As I understand the article summary, it states that:the NoError tag is updating in Kepware, but the NoError value in ThingWorx is not updating, the cause is that only the NoError tag is bound, and the suggested resolution is to bind a device static tag on the same Thing together with _System._NoError, ensure that the static tag completes its first scan, and then verify that the NoError value updates in ThingWorx.However, from my understanding, _NoError is a system tag representing the device communication state on the Kepware side, while ThingWorx is in the client position relative to Kepware.Because of that, the explanation that _NoError is not evaluated until a normal

Hi, I have been trying to upload new attachments for Detail case 18053094. When I try to upload, It seems that nothing happens and nothing appears in Case History. It is important for us to solve the problem as fast as possible since it’s a quite urgent case

If I create a notification entity in composer, and a trigger, it will put information about this in 2 tables in the DB (notificationcontent_model, notificationdefinition_model). When I delete a trigger, it is not deleting this row from the table. Because of this, I cannot create a new trigger with the same name on the same notification entity. For now, I have been deleting this row in the DB table in order to ensure this name is available for use again. I also noticed the same thing happens if you delete the entire notification entity. None of its data are removed from the tables in the DB. Is this a bug? Are there any side effects to removing these rows from the table in the DB when a trigger is deleted? 

Hi, I have a customer that is using Kepware Server for OPC DA / OPC UA / OPC DA communication between two systems. At the moment we are having issues with certain slow updating tags (booleans and integers) that freezes and are not updated between the two systems. Continuous updating values are no issue... The issue seem to be that the tags gets timed out and are not correctly mirrored between the systems. If we create local subscriptions on the KepServer node on the actual tags the error seem to disappear. Is there a way to configure kepware to establish the subscription to the source tags regardless of the client status? We cant find any correlating error messages in kepware. 

The official documentation for the Collection widget incorrectly describes the collection data binding requirements.The documentation states that collection data should be bound as { "Prameter1": "Column1", "Parameter2": "Column2"}Where the parameter defined in the child mashup is the key and the column name of the data source is to be used as the value.This is backwards both to the tooltip shown in the mashup composer and to the actual function. The tooltip correctly states that the mashup property binding is a JSON object with Infotable fields as its Keys and mashup parameters as values. I have confirmed that the tooltip version is correct and allows the collection to function as expected.I would like to see the documentation error corrected as it misled me and wasted development time

We have a connection issue between KepserverEx 6.18 and Janitza UMG96-S2 power measuring device. The connection is working and the tags can be readed via QuickClient but during the reading the quality of some tags randomly switching from good to bad for a while. The strange is that not all of the tags quality switches and it happens randomly. Does anyone has a similar issue with a Modbus TCP connection?
