Kepware

Goal: I have multiple OPC UA Clients who will connect to the OPC UA Server (Kepserver). Trust every client is getting difficult. I cannot make the Security Policy to "None".I have created a common CA. Created a server pfx file and imported in Kepserver in OPC UA Configuration Manager>Instance Certificates. Imported the CA.dar file in Trusted Client List.I have created certificates and private keys for Uaexpert and signed them with the same CA.Created CRL and pasted in C:\ProgramData\Kepware\KEPServerEX\V6\UA\Server\crlStill I am facing problem while connecting.Is it possible to do this? Is there any other process to achieve the goal? Please guide me.

I have used KepServEX for many years without issue - but running the latest version for some reason the I/O addressing is backwards. Digital Inputs are controlled with %Q - does anyone know why this is occuring?

when I used KEPSERVEREX 6.16 for customer First it failed to automatically tag generate device (ODBC client), than I search in the community, follow the instruction, change settings about runtime process from system service to interactive mode; it can generate the tags of ODBC client. Second I see the service of windows no runtime service, then when windows lock or log off the system automatically it will kill the application but not the service of windows, So are there any solutions to solve it?

Hello,I would like to receive at the exact same time all the tags values from a data logger when one of the value of the list of tags change. To do so, I tried to use the 'Log on data change' from the Trigger but sometimes I have a delay.Do you know what I could change in the parameters of the data logger to receive all the tags at once ?

Hey there,   First I want to say that I am rather new to this, just learning my way through an existing system. I don't know a ton about APIs or KEPServer. I've been tasked with taking wireless sensors and retrieving their data through Rest API. The sensors are known as Alta Monnit Sensors. Their web portal showcases a way to retrieve data this way.    They also have a guide on how to receive the data utilizing Postman Now I believe what I want to do is create on IOT Gateway Agent, use "https://www.imonnit.com/json/SensorGet?sensorID=1220966 " as my URL, POST as my method. However from here, if I'm on the right track, I'm not sure how to get the data into tags.   Any advice?

Hi all,I am currently working on having a manufacturing execution system (MES) my company uses to writeback values to one of the PLCs it talks to. Our MES is on a virtual machine, let's call it APP014 & Kepware is also installed on this server. RSLinx/our OPC topic configuration is held on a separate server, called "GE".Our current communications configuration is using Kepware as a middleman to talk to RSLinx (in other words, Local Kepware to Remote RSLinx) so that we can retrieve tag values from our PLCs. This is done as a read only process; we are using these tag values to provide real-time data to our MES. However, OPC writeback has never been implemented.Contacting the OEM of the MES, I am able to writeback tag values to the Kepware OPC server, but I would need a separate functionality that writes the values from the Kepware server back to RSLinx, in order to edit tags in the reverse.Does anyone know a way to perform this?Thanks!

Dear team, I have one query, want to covert binary data from the PLC or OPC 16 bit data word. Is it possible in Kepware using any Advance tag or other driver plugin?  

When I open KEPServer it gives me an error that says "Connection attempt to runtime failed" in the event log. Then it times out and gives me a dialog box asking if I want to work offline. The latest project was not showing. I tried to open the project, but it had not been saved. So I tried to open an older project. It opened and I tried to connect the runtime and again it failed. I checked Task Manager and the runtime is running.  I updated the license an hour ago. I got a "Success" dialog box. Does anyone know what is going on and how I overcome this problem? Thank you, Scott

I'm having problems connecting KepserverEX v6.1 to Thingworx v9.3 I can confirm that the pc that kepware is installed on can see the Thingworx server (I'm able to access composer and port query confirms port 443 is open). Thingworx’s Industrial Thing’s Base Thing Template is set to “IndustrialGateway” and the appkey is correct. I have also tried both Host name and IP of the server. This issue is effecting 2x clients both running kepserver v6.1, the reason for the low version number is that both clients were setup 5 years ago to run an Etch line and Penetrant line and we are only now wanting to connect them to Thingworx. Unfortunatly the OEM who did the initial install has gone bust so I'm unable to raise suport ticket via them

Looking for a better understanding of the error we encountered in Kepware: "<DEVICE> | The following errors occurred uploading controller project from device. Resorting to symbolic protocol." We had an issue in our plant where connectivity between Kepware and several Allen-Bradley PLCs were dropping out intermittently due to a networking issue.  Approximately 3 minutes after this event started, we saw the above error message posted for all PLC's involved.  While the message states the "following errors occurred" we never saw an actual message with details.  Just the line above.   For context, all PLC's involved were originally setup with Logical Non-Blocking addressing.  Kepware changing/resorting to using Symbolic addressing appears to have overwhelmed a combination of the PLC, network and driver.  We were unable to recover until we restarted the Kepware server. We've seen Kepware make the switch to Symbolic addressing when

Does anyone know if there is a way to export the asset inventory from Kepserver?  Looking specifically for a list of the devices at a site with their name, IP and/or MAC address, and anything else we can get.  Would be interested in the API call as well if there is one.

When communicating with Mitsubishi PLC via Mitsubishi Ethernet from kepServer, I wonder if it is difficult to link if they are on different networks.I have already confirmed that linking is possible on the same network.----------------------------------------------------------Translated the topic from Korean to English using google translate.Body - kepServer에서 Mitsubishi Ethernet을 통해 Mitsubishi PLC와 통신할 때 다른 네트워크에 있으면 연동이 어려운지 궁금합니다.같은 네트워크에서 연동이 가능하다는 것은 이미 확인했습니다.-By Community Moderation Team.----------------------------------------------------------

Hello community, We're experiencing issue where errors attached bellow pops up and it seems like this problem causing outages in our MES visualization system. Any ideas what can cause this error message or how to deal with it? Thanks in advance for suggestions. JT  

I have a problem about I changed the location of KEPSeverEX from PC-A to PC-B I transfer the licence and save lic file and active with new PC -B but I can't connect to my PLC and  it still show time limit  ( I can monitor some data )  how to solve this problem please suggest. Thank you in advance.

Hello Team, I would like to read the value from configuration API service, How can read the Value?   

I'm not even exactly sure how to ask this question so if I seem ignorant that's only because I am. I assume that I'm having an issue understanding a fundamental concept of interacting with an OPC UA server.  I'm attempting to create an OPC UA client in Python to ultimately read values that originated from Modbus PLC registers. The targeted PLC is successfully connected to KepServerEX6 and values from registers are being pulled into KepServerEX Project>Channel>Device>Tags perfectly. The data (values from PLC registers) is being and has been successfully used from this KepServer by another application for several years so KepServer and connections to multiple PLCs (multiple brands) is working just fine. Python code completely aside, in a 3rd party OPC UA client application (UaExpert), I can connect to the OPC UA server, I can see a lot of things about the server/KepWare, (Root/Objects/Server, ServerCapabilities, ServerDiagnostics, etc) but the Objec

I am using KepServerEx (version 6.16) OPC DA client to access ABB MicroSCADA OPC server data.I am able to access OPC tags using the connection parameters. But when trying to read data using the OPC channel, i am getting the BAD vartype errorPictures (1-5) If I directly add OPC server to OPC client, and import tags to it from the same server, i am able to read all the values.Pictures (6-7) 

Hello community,Is there a way to check what the real error is in KEPServerEX for SQL diagnostics? This doesn't help at all:Date Time Level Source Event12/08/2024 16:39:18 Error Data Logger Plug-in Unknown error while executing query in table 'mytable' for log group 'datalog-azure'. I am guessing it's something about security/privileges since I am trying to log data in an Azure database.I am able to see tables, columns when I am mapping the data but unable to write values to table.Using app version 6.16 (V6.16.203.0)  Any help is appreciated. Cheers, 

I am trying to configure Datalogger and keep running into issues in the configuration. I have created my DSN correctly and it successfully passed the connection test. But whenever I try to select the table name, the dropdown list does not show any of the tables in my database. I attached a screenshot of what shows up in the dropdown. 

Hi, I'm Refsam Maulana, a technician who is working using the kepware applicationI have a question about kepware, related to OPC DA Client on a domain system. How to make computers that have different IP scopes, but in one domain to be read on the client's computer? Or is there a way to add servers manually instead of choosing from the Microsoft network?Me and my coworkers still haven't figured out how to read the servers on computers that have different ip scopes but in the same domain.    Hoping to get a solution 

Good morning, I have a problem connecting to some OPC UA Clients.Sometimes I get this warning:Warning OPC UA Client XYZ.B&R | Read request failed on device. | Status description = 'The operation timed out.', Status code = 0X800A0000.When it happens some tags are in 'Unknown' quality and until I force a synchronous write the status cannot return to "Good" status. I tried to change "Asynchronous Reqst Timeout", but increasing it immediately returns the value to the default of "1000". Let me know please.Thank you.Regards

I am working on a solution that involves creating tags using the Kepware Configuration API. I have been able to find documentation for and create normal tags, but I can't seem to find any information on how to create Advanced Tags using the API. I have looked through the Advanced Tags help guide as well as the Kepware Server help guide but it doesn't have any documentation on how to create advanced tags using the API (unless I am missing it somehow). Can anyone confirm if advanced tags can be created from the API and if so is there documentation on how to construct the API call? If anyone could point me in the right direction that would be greatly appreciated, thanks!

I have upgraded KepServerEx.V5 to V.6. It can communicate with ControlLogix before upgrading. After upgrading to V.6. 

Hi all, Fairly short question, but is there a way to get all tags among all tag groups on a kepware device using the configuration API? I am finding that I need to be specific in my API calls and specify the tag group, but I'd like to be able to get all of the tags for the device in one call. Thanks!
