Kepware

We are getting lots of tag from PLC devices (40+) to Kepware. Sometimes, due to some reason the connectivity is lost  between PLC and Kepware. So that we facing data loss issue. Is there any mechanism within a Kepware to address this connectivity loss? How to identify this connectivity loss from ThingWorx for all PLC devices?

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

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.

  

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.

Hi,  I'm currently using a trial version of KEPServer EX 6 for some testing and research. In my current set-up, I have a Matrikon OPC DA simulator server simulating some data for some tags. Then I have the KEPServer connecting to the Matrikon OPC simulator server via the OPC DA Client Driver, The KEPServer is used like a middleware to convert the Matrikon DA Simulator data into OPC UA protocol, for OPC UA clients to retrieve Matrikon DA simulator data. I have an OPC UA adapter that connects to KEPSever OPC UA Endpoint to retrieve the data and sends it to another timeseries historian.  Configuration for kepware da client: Scan Mode: "Respect Client-Specified Scan Rate", Update Mode: "Exception:. Configuration for OPC UA Adapter: Polling (every 2 mins) Here is where I made some observations which I can't comprehend: 1. At first glance, the connection from my OPC UA Adapter to Kepware Server is fine and I continue to receive data. However, when I re

I am currently using KEPServerEX 6 demo and trying to establish an OPC UA connection with UA Expert for testing purposes. I have successfully configured a device (Omron NJ via Ethernet) and am able to browse and render the tag database correctly within KEPServerEX.However, I am experiencing the following issue:When I try to connect to the server using UA Expert, I get the following error:BadSecurityChecksFailedorThe server does not support the configured security policy "None"It seems that KEPServerEX is not allowing connections using the "None" security policy.I want to change the security policies in kep, but i cannot find any option to enable or change the supported security policies. It looks like the interface doesn't expose these controls.What I have tried:Checked and restarted the KEPServerEX Runtime.Confirmed that the OPC UA endpoint is active at:opc.tcp://<my-ip>:49320Tried changing the security mode in UA Expert to match KEPServerEX (e.g., None/None, Basic128Rsa15, etc.

Hi,I am using Kepserver 6.10 and trying to communicate with Lovato DMG610. DMG610 is communicating with NB114 (Serial to Ethernet Converter) and NB114 is communicating with Kepserver. There are total 13 devices connected. I am unable to define slave and Modbus address of DMG610 in Kepserver.  Kindly provide a solution for this. I am attaching the details for further referencing.

I have Kepware Ex6 set up as OPC UA client, connects to Igniton as OPC UA server and real time data are coming through. I like to send them to Rockwell tudio5000 V31 platform ( L72 processor) . Looking for help., Thanks.

At infrastructure level we migrated from VMWARE to Nutanix and after this we keep having this issue everyday. The only way it is getting auto resolved is after reboot. We can do this now since only test environment is migrated and we are soon planning to migrate production environment as well. In that case every time reboot is difficult as production activities will get interrupted. Is there a way to fix this issue? Like deactivating and activating license again? or changing the license type to offline one? Repair option in license utility will fix this? Kepware OPC connectivity suite verison 6.11.764.

Is it possible to use a Kepserver as a gateway/proxy between fx. a Beckhoff PLC and a Rockwell PLC?

Hello, I've created connection with my Rockwell PLC. I'm able to read all the data, However I'm unable to write anything. CS433164 - OPC DA Client driver Async Write 2.0 failed with Callback item error: "0xC0040006" in PTC Kepware Products Tags in PLC are R/W. What can be the issue?

Hello Community,I have created a trigger for already created Log group in Thingworx Kepware Server v6.16 Data Logger.Other triggers are working but created trigger is not working.Created Trigger:1. Always Trigger2. Trigger on Data ChangeAny solution?

I am using the datalogger in KEPServerEx 6.16 to store "frames" of data to SQL. Things like recipes and test results, where I have a single set of data that I want inserted all at once. I have  a way set up that works pretty well. I stage the data to be sent in a buffer in the plc, set the datalog trigger to start and stop on a specific tag and to log all items on starts, and when the data is ready, I activate that trigger and read back the msg_count incrementing as an acknowledge it was sent to reset the trigger and stage the next data. I found that every once in a while, I would get a null or double entry in my database doing this method. I did some experimenting, and what I believe is the cause is occasionally the trigger would be read before all the data had. The trigger is set to update every second while the log data is only every 100ms, so in theory that shouldn't happen. I seemed to have fixed it for now by simply adding a timer delay between staging the dat

We are looking to manage all kepware tags from a central server. Once testing is done, we currently need to export and import these tags into 14 other servers that have Kepware installed. This is tedious and prone to error.   I know I could copy the project file from the central server and copy to the remote servers, but this would entail taking down the Kepware service copying the file and then restarting the service.  I'd prefer to not have to do this.  Is anyone familiar with a tool/program that will compare/sync all Channels/PLCs/TagGroups/Tags between two servers and perform the update without having to take down the services?
