"State definitions" for values, not only styles

Have service where I receive infotable, and show it in grid.One of column is STATUS, with integer values to present OK/NOK, maybe different in future.Style for whole row is set acc. STATUS column, so if there is 2 (which means NOK), whole row is described in red.Is there also a way (configurable via mashup, style definitions, etc.), to display NOK instead of 2, OK instead of 1, etc.? Or the only way is to change it inside service?

ThingWorx cache

What’s the best way to cache data in ThingWorx?Should I use properties, configuration tables, or user sessions (of course user session is valid only for user)?Are there other options available? If the value changes very frequently, is there a better alternative to Thing properties?If the value changes less frequently, what’s the best approach for caching?Also, can Ignite be utilized for caching in any way? I am aware that it depends on use case and scenario. I would like to know what are the feasible options available or supported by the ThingWorx platform. Thank you in Advance. -Abhiram

Distributed Timer Execution in a HA Cluster

Distributed Timer and Scheduler Execution in a ThingWorx High Availability (HA) ClusterWritten by Desheng Xu and edited by Mike Jasperson  OverviewStarting with the 9.0 release, ThingWorx supports an “active-active” high availability (or HA) configuration, with multiple nodes providing redundancy in the event of hardware failures as well as horizontal scalability for workloads that can be distributed across the cluster. In this architecture, one of the ThingWorx nodes is elected as the “singleton” (or lead) node of the cluster.  This node is responsible for managing the execution of all events triggered by timers or schedulers – they are not distributed across the cluster. This design has proved challenging for some implementations as it presents a potential for a ThingWorx application to generate imbalanced workload if complex timers and schedulers are needed. However, your ThingWorx applications can overcome this limitation, and still use timer

Menu widget opens Mashup as full page instead of inside Contained Mashup

I am facing issues regarding Menus not changing Contained Mashups and instead overriding the parent mashup when clicked. This issue was noticed when loading projects developed on Thingworx 9.3/9.4 onto Thingworx 9.5 (ThingWorx 9.5.4-b764). The attached project functions as intended on Thingworx 9.4 (ThingWorx 9.4.0-b49) but not on Thingworx 9.5. The menu is correctly configured (having DrivePageMashupOrBindToMashup set to "Bound to mashup parameter"). Like I said, the exact same configuration functions correctly on TW9.4 but not on TW9.5.

Python scripts used read data from the Kepware stops reading data intermittently.

Hello, I have a multiple PLCs in the operation lines. Each PLC has operation data from single or multiple machines. I read data from them in a single KEPServerEX. From there I am reading data in a Linux server with the help of a Python script which uses asyncua and asyncio to read data and then it stores in a postgresql database.I read data from Kepware in 1 second interval. But sometimes I lose data from any of the machines which is connected to the PLC where as data from other machines are fine. Problem is that everything will be fine for hours and suddenly we lose data from any of the machine. There is a single python script to read all data. asyncio parallel execution method is applied to read data from all machines at a time. When terminate the python code and execute it again everything becomes normal. Can you please say what could be the probable issues and how to fix that.

Java SDK - How can I pass a function call to ValueCollection

Hello,I am using the Java SDK to invoke service QueryImplementingThingsOptimized  let result = ThingTemplates["LoraDeviceGenericModel"].QueryImplementingThingsOptimized( {    maxItems: 1000,}); The corresponding Java code is as follows; ValueCollection getEntityListParams = new ValueCollection();getEntityListParams.SetNumberValue("maxItems", BATCH_THINGS);getEntityListParams.SetNumberValue("offset", offset);InfoTable queryResult = thingClient.invokeService(ThingTemplates, "LoraDeviceGenericModel", "QueryImplementingThingsOptimized",getEntityListParams, TIMEOUT_30_000_MS); But this call could be optimized by using a filter on returned fields; function entityList(inarray) { let out = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape({ dataShapeName: 'EntityList' }); inarray.forEach(entry => out.AddRow({ name: entry, description: entry })); return out; } let result = ThingTemplates["LoraDeviceGenericModel"].QueryImplementingThings

Oracle Autonomous Transaction Processing (ATP) database 19c is not working with KEPServerEX

Hello, Our company's custom MES application uses an Oracle database on the backend and connects with the shopfloor PLCs using the KEPServerEX OPC server. We plan to migrate the MES application (Full-stack - database + Middleware + UI) and the OPC server machine to Oracle Cloud. Below are the existing configurations: Oracle database 12c Rel 2OPC ServerWindows Server 2019KEPServer EX 6.9.584.0Oracle Instant Client 12cOracle ODBC Driver 12cAs part of the migration, we want to upgrade the Oracle database to 19c and switch to the Oracle Autonomous Transaction Processing (ATP) database. We have set up the ODBC connection using the Oracle 12c ODBC driver and instant Client 19c (we also tried the 12c client). KEPServerEX can connect to the ATP database; it can read but not write.  Desired Future ConfigurationsOracle ATP database 19cOPC ServerWindows Server 2022KEPServer EX 6.17.240.0 (The older version 6.9.584.0 cannot even read from the Oracle database)Oracl

Send all tags to iotGateway only on data change using advanced tags using kepserverex 6.15 version

We want to send data of all the tags to iot gateway only when value for 1 of the tags changes using kepserverex 6.15 version. We've tried combinations of publishing on intervals(wide format as well as narrow format) and on data change using Every Scan and On Data Change option for each iot gateway tag. How can this be achieved using advanced tags(linked tag or derived tag) or is there any other alternative to this?

Issue with Infotable Property Logging and History Updates

I have an Infotable property that is enabled for logging and is persistent.This Infotable contains three columns: Number, StartDate, and EndDate. The table is updated every 24 hours.The update logic is as follows:I first assign the Infotable to a variable in the script.I modify the dates as needed.I update the property using me.property.While this updates the Infotable with the new values (updated dates), when I query it using QueryNamedPropertyHistory or QueryInfoTablePropertyHistory, I only see one log entry for the property instead of a complete history.Could you help me understand why the logs aren’t being recorded as expected?Thingworx version -> 9.3.8

Organisation & User Groups & Composer

Hi,   I have created an Organisation and attached the 'Users' user group so that All the Users can log in from the Organisation.    However, all users are able to log in to Composer, even though all articles on removing User access to Composer have been tried.   So how comes this composer access can be restricted if the user group of the user is assigned to an Organisation   Thanks,

Mapping for AD Users based on Group ID over Group Name

Good day everyone, Today we changed the name of a group in our Active Directory and as a consequence we locked all users relying on that group out of the system for a while until we figured out where the problem is coming from - apparently, the connection between AD & Thingworx is based on the AD Group's name rather than its unique SID. For organisations where names can change frequently, this is quite the issue - is there any way around this currently? Kind regards,Martin
