IoT & Connectivity

Hello We are using KEPServerEX 6.17.240. We are trying to diagnose an issue with frequent disconnects between a Siemens PLC and KEPWare, communicating over OPCUA. We are looking at the OPC Diagnostic log from View -> OPC Diagnostic and I am looking for any documentation for how to interpret these events.   For example, we are continually getting these "ServerFaultResponses" (which are timeouts associated with a previous "PublishRequest". But there's really no documentation I can find to help interpret these. Some of the other logs have an actual program name in the brackets, where as this example has a seemingly random number. Is there a way to associate this number with a process? Is this number generated somehow by KEPWare or something like a ClientID from the actual OPC Client application?I'm basically looking for extra information about what some information in these logs mean, specifically for helping to interpret why we are flooded with timeouts and th

Hello! With reference to this topic i have talked with MAzak and in the new versions of the controller you can activate the CVARs, but the problem so far is y only can see the System and assets which at least in kepware we do not see the tool life/ Cvars Value, i can only see those in the XML locally

Hi all, Looking for more information on the service mentioned in the description. Mainly more information or examples on formatting for the inputs of the service as the descriptions seem limited for someone without experience on using the Analytics functions of Thingworx. Thank you!

KEPServerEX 6.15.132.0We have 8 Allen-Bradley Compact Logix 5300 PLCs connected on individual channels using the Allen-Bradley ControlLogix Ethernet driver via a wireless Moxa Gateway device. We also have 4 Siemens S7 PLCs that are configured, but are currently powered down and offline. These devices have been connected for almost a year and working without issue. This morning all of the tags on all of the connected devices began showing Bad (Out of Service) tag Quality. Nothing has changed on the KEPServerEX side that we are aware of. The KEPServerEX event log doesn't show any errors, just a few warnings where devices that are not online have been automatically demoted, and auto-promoted to determine if communications can be re-established.We have restarted KEPServerEX and rebooted the Windows 2022 VM Server that KEPServerEX is installed on several. We can ping all of the connected devices and can Telnet into TCP/IP Port 44818 on all of the devices. We disabled all of the devices exce

1) Top diagram is work properly before. Due to client's decision and to avoid the data lost because of client/server certificate need to renew every 3 years. we are agreed to change the security policy to "None"2) I have completed change the security level to "None" on the UA sever side. I have perform the loop back test and it's successfully (re-create the channel to connect locally).3) When I want to change the security policy from "Basic256Sha256" to "None". the setting on the UA client keep fall back to "Basic256Sha256" once I click the Apply and OK button.4) I tried to disable the tag scanning and configure, the result still the same.would it be the Authentication issue? default OPCUser issue? the log of the configuration HMI is showing i'm the administrator. seem like I can't update the security setting on UA client.

Everyone is talking about Generative AI, Large Language Models (LLMs) in particular. They are being used to provide Customer Service assistance in Chatbots, automate writing code in software development, summarizing long articles, documents, and data stores, among many other use cases. LLMs have the ability to ingest huge amounts of data, process queries related to that data, find patterns, and provide answers to natural language questions asked of the model. Could LLMs be used to provide greater insights into factory floor operations? The answer is most definitely yes! And ThingWorx can be used to facilitate this capability. ThingWorx enables connectivity to sensors, systems, and databases on the factory floor to monitor and analyze operations. Linking ThingWorx to an LLM establishes an AI Assistant capability that can provide personnel with valuable insights on the floor that can greatly reduce downtime and increase overall productivity.A new Best Practice has been developed tha

  

I'm trying to communicate CompactLogix L-18 ERM QBFC1 (firmware version 20) with Kepware (V6.13) and facing one strange issue.If I add the tags manually, I'm getting bad quality data in Kepware. If I try to add tags using automatic tag generation, I'm able to get few tags with good quality data but not all the tags present in the controller. Using .L5K file option, I'm able to add automatically all the tags present in the controller but data quality for all the tags is showing bad.Please help.

Hi, I have set up a number of temperature/humidity hardware controllers to a KEPserverEX.These hardware controllers will have to be powered off from time to time when the hardware is not being used.The client is a log software that automatically generates monthly data log files and requires noadministration.When the hardware is shut down it will generate a fault in the KEPserverEX event log and the client will time out on these OPC channels. Client log interval is 10 minutes with a scan of 2 cycles/s and channel. If I use the Auto-demote in KEPserverEX will the client receive anything else but a non response and time out on each request made to a non powered controller? I am open for any suggestions but particularly interested in the Auto-demote function. Would the Auto-demote add anything positive to my timeouts or is there a better way to handle this state? I am using KEPserverEX v6.9 and protocol Modbus RTU serial using Ethernet encapsulation.

I have a Thingworx 9.1 instance and am looking forward to upgrade it to 9.7. The instance is using the SQL DB. And we are planning for migration upgrade.What would be the easiest way to do this?1. Should I Upgrade to an intermediate version before upgrading to 9.7?2. Should I directly install 9.7 version in the new server and export the custom apps from 9.1 and then import it to 9.7? 

I have an output from my SQL database saved as an InfoTable in ThingWorx (I've already filtered the timestamp before extracting it). How can I average all of the data in my InfoTable? I couldn't find a way to extract the data into an array (if that's even possible).

Hi, I am very new to thingworx. I created a very basic mashup with a form where the user can enter data. What I don't understand is how to ensure the data entry is saved somewhere. How does this work in thingworx? I would like the form to be saved somewhere once its filled out with a possibility to edit in future if needed.

I have parent mashup and 2 child mashups. I am showing the child mashup as pop ups.The flow of pop up is1. A button is clicked in parent mashup and child mashup A will show up.2. A button in child mashup A is clicked and child mashup B will show up without A closing.3. A button in child mashup B is clicked to update values in A and close mashup B.4. Mashup A is present after closing of B but data did not update real time. How to enable refresh real time for mashup A?

Hi is this topic solved?? Help need because I have the same problem. I have parent mashup and 2 child mashups. I am showing the child mashup as pop ups. Child mashup A has navigation button to child mashup B. When I click a button in Mashup B, it will close. Now, I want the child mashup A data to refresh. How do I do that?  

We had accidently built custom extension using java 17 whereas the environment was on java 11. Upon importing this extesnion on ThingWorx the environment was not coming up and below error was observed in tomcat logs: java.lang.UnsupportedClassVersionError: com/thingworx/extensions/sshExtension/SshServerThing has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0. Removed the extension entry from postgresDB by deleting the corresponding entries from table extensions, extensionpackage_model and model_index after this the environment became accessible. Also, the entry was deleted from thingpackage_model and widgel_model.Post that also when we are trying to import the correctly build extension its giving below error:Unable to delete Extension zip file from storage. This is likely due to other errors: [1,018] Data store unknown error: [Error occurred while accessing t

Performed in place upgrade from thingworx version 9.3.8 to 9.5.7 and several system tokens seem to be missing. Windows server 2019 MSSQL 2019. Example screenshots below. Is there a place to download the system localization tables for english and spanish?
