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

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 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. 

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

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

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. I want to create a service which goal is,Fetch ~500 records from a ThingWorx StreamInsert them in a single bulk operation into Postgres using a DB Connector.please anyone can help me how to create this service and their logics. 

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

Hello,I have a PLC program which send the DTL from the PLC, although I can log the timestamp based on the SQL side, is there anyway to log DTL directly from PLC to Kepware with the new/upcomming updates ?

Hi, I currently use LinkMaster to map tags between my field devices and PLC. I want to get rid of LinkMaster and do the mapping in Kepware Server. I currently have Version 6 of KepServerEx. Do I need to update to V7 in order to use the advanced tag linked tags feature or is that available in the version I have now? Also, is there a way to just export my LinkMaster tags and import into Kepware or does it have to be a manual migration? Thanks 🙂

先前客戶在 ODBC 做讀寫，再透過 OPC UA 提供給 InTouch。每日固定時間會出現數值異常。我們已經更換過 Server 環境，也更換過資料庫（MSSQL / MySQL）。若直接接收溫度資料則是正常的，使用 Local Historian 也是正常的。我們嘗試過許多測試方法，目前的結論是：只要資料經過 ODBC，就會發生異常。異常現象大約持續幾分鐘，在這段時間內，A 項數值會突然升高，B 項數值也會升高（沒有太明顯的規律）。而且只會發生在特定時間。想詢問 PTC 或其他夥伴，是否有遇過類似案例，或有任何可能的原因與建議方向。Previously, the customer used ODBC for read/write operations, and the data was then provided to InTouch through OPC UA. Data abnormalities occur at a fixed time every day.We have already replaced the server environment and also changed the database (MSSQL / MySQL). When temperature data is received directly, the values are normal. Using Local Historian also works normally.We have tried many testing approaches, and the current conclusion is that the abnormality only occurs when the data passes through ODBC.The abnormal behavior lasts for a few minutes. During this time, the value of item A suddenly increases, and item B also increases (without a clear pattern).This issue only occurs at a specific time each day.We would

I use KepserverEX6.14 for linking Rockwell and siemens PLC's.We have 207 link tags in both directions. But we have troubles with 1 Siemens 1512 PLC when the communication drops (without voltage or network troubles). After the communication restores, kepserver can read the datablocks but CAN'T write to the datablock. The solution is then disable-enable tags, after this everything works like it should. My datatypes are boolean's and words (not defaults).There is a scan rate of 2000ms for PLC values. And the linked tags are written when input changes.I have tested with Auto-Demotion on and off (also with 'Discard Requests when Demoted' on/off) What can i try else?

Hi, I need to connect to KepserverEX 5.8 in a Windows 2000 Pro/Sp4 workstation with Ewon Flexy 205.The goal is using the ewon (in this case 5 of them) as middle point to communicate s7-300 PLC with Wonderware 8.0 using KepserverEX 5.8 as the OPC server. When configurating KepserverEX 5.8 channel i use OPC UA and configure UA server in the channel (see attachment 1) and when i try to import items on  the device to import the tags of the Ewons an error appear (see attachement 2).See attachement 3 for ewon configuration.Any suggestion to address this?

Hello, im setting up tags in Kepware where previously we have used RS linx, the booleans tags are all showing 0 when it should be a 1 and are not changing at all. The quality of the tag is good and its showing correctly (1) in RS linx but a 0 in kepware, anyone got any advice? Kepware server 7

I am trying to get a hold of Sales in order to purchase additional license options on my Kepware OPC Server package.  I have tried submitting a ticket but I received a "you are blocked" response to that.  I've tried calling but after being on hold for nearly an hour, it just disconnects me.  I mean, really?  I'm wanting to buy stuff from you.  Does PTC really make it that difficult to make a purchase?  Can someone PLEASE contact me? m.barnes@amrize.com

使用者希望使用有效期限為10 年或更長的自簽名憑證。使用原有的KEPServerEX客戶端時，只需一個憑證即可實現雙向通訊。然而，由於架構較為複雜，目前似乎無法在多個系統間重複使用自簽名憑證。請確認自簽名客戶端憑證是否可以被多個伺服器使用。OPC UA證書會自動續約或延長有效期限嗎？如果用戶端憑證過期，是否會影響現有系統？例如，是否會導致EAP無法連線等問題？ The user would like to use a self-signed certificate with a validity period of 10 years or longer. With the original KEPServerEX client, only one certificate is needed for mutual communication.However, it seems that a self-signed certificate cannot currently be reused across multiple systems, possibly due to the more complex architecture. Please confirm whether a self-signed client certificate can be used by multiple servers.Will **OPC UA certificates automatically renew or extend their validity period?If the client certificate expires, will it affect the existing system? For example, could it cause issues such as EAP being unable to connect? 

Hi! Has anyone used the KepServer Siemens Suite with Siemens new S7-1200 (G2) CPU's? Best regardsPär

各位先進夥伴好，近期接到一個CASE，客戶突然想做升級，4版到7版(當前最新)。Dear partners, recently we encountered a case where a customer suddenly wants to upgrade from Version 4 to Version 7 (the current latest version).因為4版真的太過古老，最簡單的OPF匯出，都不知道能否順利？想討論有甚麼注意事項。Since Version 4 is extremely old, we are not even sure whether basic functions such as OPF export can be completed smoothly. We would like to discuss what considerations or precautions we should pay attention to.軟體、系統、硬體都可以。Any suggestions related to software, operating systems, or hardware are welcome.
