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 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

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

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 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?

We are using CWC as a solution to provide work instructions to employeesOver 1 year there is a table that growing very fast called workdefinitionhistory (reaching the 1TB soon)What will be the effect if this table will be cleaned?Is there a PTC way/best practice to clean the table?my plan is to archive and move the data to a different storage.

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?

As per the original post.   Hi,   I have the similar problem as NM_12850686. Could you please share the port issue solution?   Here is my setup: Cleco Controller mPro200 - Open Protocol - Port 9002 - Activated Cleco Controller mPro200 - TorqueNet- Port 12345 - Activated Cleco Controller mPro200 id : 192.168.50.20 KepServerEx - Channel:TorqueToolEthernet - Device:Cleco (Open Protocol - 192.168.50.20 - Port: 9002)   Both the controller and the port can be ping successfully from the PC.   However, none of the tags receives information from Cleco. Could you please look into this?   Thank you,LP

Hello Everyone,I am working with the WebFrame widget in a ThingWorx Mashup and facing an issue related to loading indication.When the URL inside the WebFrame takes time to load, there is no built-in loading indicator or event to detect the loading state. I want to display a custom loading indicator (spinner) until the URL is fully loaded.My requirements:Show a custom loader when WebFrame URL starts loadingHide the loader once the URL is completely loadedChallenges:WebFrame does not provide any loading status or onLoad eventI cannot reliably detect when the content has finished loadingAdditional Issue (Event Router):I tried using the Event Router to control a BOOLEAN variable (e.g., isLoading) for showing/hiding the loader. However, I am not sure how to properly pass or assign TRUE/FALSE values through the Event Router.Questions:Is there any way to detect WebFrame loading start/end events in ThingWorx?What is the best practice to implement a custom loading indicator for WebFrame?How can

We are experiencing inconsistent data loss between KEPServerEX V6.13.266 and our Atlas Copco Torque Tools. Specifically, torque results are missing in the following scenarios:Power Cycles/Battery Swaps: Results fail to report immediately after switching the tool ON or swapping batteries.Intermittent Drops: We are seeing partial data transfer (e.g., only 5 out of 9 tightening cycles recorded).Please review these cases and provide your recommendations or potential fixes to resolve these synchronization issues.Kindly setup the call to discuss or need more informationThanks,MuraliKrishnan

Hi everyone, I’m currently learning ThingWorx and trying to connect a small IoT setup, but I’m a bit confused about the correct architecture and would really appreciate some guidance. My current setup uses an ESP8266-based NodeMCU board to read data from a wireless AC current sensor. At the moment, the ESP8266 collects the sensor data and displays it on a local web server using an HTTP client. That part is working fine. Now I want to extend this project so the device can send the sensor data to **ThingWorx for monitoring and analytics**, ideally using **MQTT** since it seems to be the common approach for IoT communication. From what I understand so far, the workflow might look something like this: Sensor → ESP8266 → MQTT → ThingWorx However, I’m unsure about a few things: Do I need to install and run a **separate MQTT broker** (for example Mosquitto) between the ESP8266 and ThingWorx?Does **ThingWorx provide its own MQTT broker**, or does it only act

I have stream which have data in 11 columns, and rows have data as well as null values.

Hi Community, I am currently working on an integration scenario where I consume data from multiple external APIs (e.g., SAP, APLUs and 4 additional interfaces ).   Each API delivers data in a slightly different structure, but the overall processing logic in ThingWorx is quite similar: Call external API Receive data Perform transformation / validation Execute business logic Return structured output To avoid duplication and improve maintainability, I am considering the following generic approach: Proposed Approach Create a Thing Template that contains: Generic input definitions (API endpoint, headers, payload, etc.) A standardized output structure (e.g., JSON) Shared services for: API execution Data transformation Error handling Logging Then create individual Things inheriting from this Thing Template for each interface (SAP APLUs, Interface2, Interface3, etc.) Override only specific logic where necessary This way: Core logic is centralized
