Kepware

We cannot connected the Kepware sever to the DxP(OPC UA client) using  "Basic256 sing"But We connected the Kepware sever to the DxP(OPC UA client)successful on no security. When I turned on encryption, the following error occurred on the client side."Selected security is not found in server endpoints"Please tell me what to check. 

We are running KepServer to monitor our equipment, but we are having frequent disconnection of the system causing data monitoring loss. When we Re-Initialize KepServer, I get the below error I am not sure what to do to correct this issue  

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. 

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

I am looking to evaluate multiple tags in my Advanced Derived Tag with a String output.  I would like the output to be the following machine states: "Running" or "Idle" or "Down".  Is this possible?

Good afternoon. KepServerEX V5.21 I would like to implement a periodic backup of the runtime project: is there a method to do this via the command line by running a batch script or using API calls? RegardsPaolo 

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?

HiWe need to capture the timestamp property of a PLC tag through advance tags module.   We need  the hour in which the data of one tag has been changed..  How can we do it?   We are using kepserverEX  v6.16.203.  Thanks in advance

I've made a Kepware configuration for about 10 Rockwell plc's. But i have an error on one of them. All other 9 are working fine.It is a 1756-L72 CPU where i have issues to connect with. We've a working connection to another PLC with the same configuration which is working fine.I don't see an error message in the diagnostic list of Kepware. what is the best way to proceed with this to find a root cause and a solution?

Hi Support,  I am trying to filter out tags during an import. Could you please provide some examples of how the leaf filtering works. I have tried different itereations and get the same results eavh time.  Thanks

Hi,Is there a possibility to stop KepserverEx + Siemens S7 Plus Ethernet from loading symbols from the PLC every time a client connects ? This takes a very long time for every client connection and really is not needed for my use case (All necessary static tags where manually added).I already disabled following settings on the PLC node:- Tag Generation / On Device Startup = Do Not Generate on Startup- Communications / On Invalid Tag = Disable

HelloI use the driver ControlLogix Ethernet to Write Data to 3 PLC the read function is good but When I am Trying to write Data is very slowly and Take more than 1minute I have switch between Logical and Symbolic but nothing change

this happens every time when I open OPC Quick Client as a read-only user  

Hi all, I am trying to create a kepware tag that only holds the maximum value for a property for each run cycle of a machine. Here is a more in-depth example of what I want to achieve with getting only the maximum and why the maximum advanced tag doesn't solve this. I have a property named XTime, that runs 3 times through it's cycle. The 3 cycles and values are as follows (between cycles the value goes to 0):{0...1...2...3...4...5...6...0}{0...1...2...3...4...5...6...7...0}{0...1...2...3...4...5...6...7...8...0} Now say I have a tag named XTimeMAX where I only want to get the max value from each run and that is the ONLY value that XTimeMAX is set as.So in this case the history of tag XTimeMAX is:{6...7...8}  This is because these are the respective maximums for each cycle. The Maximum Advanced Tag doesn't seem to do this as it sets the advanced tag value with the current maximum each time it changes, so the Maximum tag would change like this whic

Hi all, I am having an issue with how the Maximum Advanced Tag works and am hoping to get some insight. So I want the maximum value for a run written to a tag. But I want ONLY the maximum written to the tag so that is all I see. The Maximum Advanced tag doesn't seem to actually handle this since it writes all values that are a maximum and ends the cycle with the max, but I just want to see the true max for the cycle. For example, the data for my max tag looks like below for a run cycle, but I only want to see the max of 21, not the rest of the data leading up to the actual max. Any help is appreciated!  

i want to replace AB 1761-NET-ENI,  DF1 to Ethernet  with Moxa  Mgate EIP 3170  Is any one proved to connect this moxa gateway to kepserver

I just connected Codesys to Kepserver via first running a virtual PLC via codesys control win and running my program. Then I created a Codesys channel using all the general settings. When adding a device i changed the type of communications in use to CODESYS V3 Ethernet, the address when connecting to the device (Address Type: Logical Address/PLC Name and also the Logical Address to my Device Address from Codesys. But after running Kepserver it tells me my Device is not responding. I have looked at the other thread and since I am new to Kepserver and Codesys I don't really understand what is going on. The addresses for my tags should be right. Any help would be greatly appreciated. I have added lots of screenshots just in case. If you need any more let me know.

We're in the middle of migrating to new servers. We've transferred the license from one server for Allen-Bradley Ethernet per https://www.ptc.com/en/support/article/CS285278. This worked fine, and the license Utility on the new server says the license is good. But the server configurator says it is time limited and is shutting down after the indicated time elapses.  The original server was running v6.0 and the new server is running v6.12. We've restarted and reinitialized and the situation is unchanged. The only thing I've found from searching around is to try to install a lower version, which I will do shortly. Any ideas? 

Hi PTC Community,I'm currently facing a peculiar issue in KepserverEX 6.15 while working with a specific .opf configuration file that includes a datalogger setup.Every time I open this .opf file, the "regenerate column mapping rules" area, under the Advanced Log Group settings, gets altered. The Yes/No choices are changed seemingly randomly.The rest of the configuration stays intact.The project itself is offline and being used to migrate settings from an older Kepware server to a new one.Has anyone encountered a similar issue?Is there a specific setting or migration step that could be causing this?Any troubleshooting tips would be greatly appreciated!

HI All           Can I able to write OPC DA tags of Honeywell Experion DCS to Yokogawa Centum VP via Kepware Ex 6.5 software in the same OT network if yes how can i do the same.

Can we purchase latest license and activate for KepewareEX 5.20 version ?it will be great as we can avoid a middleware server to do DA-to-UA conversion.Thanks 

I am trying to connect the new omni 7000 flow computers to the Kepware omniflow driver, but these computers have a different and larger modbus map than the omni 6000 computers. Some of the registers are kept but there are others that when I try to enter them to the kepserver, I get an error message indicating that the number of registers cannot be added because it is out of range.How can I add the new registers from the omni 7000 to the omni flow driver?
