Kepware

Hi Kepware friends!I need to create two calculated tags in Kepware based on another configured tag: ArrayLength:Compute the length of the String Array Tag as an int ArrayToString:Concatenate an array tag into a delimited string. Like ValueArr0 ^ ValueArr1 ^ ValueArr2 ...... I guess the UDD is the solution, but I don't know how to do it. Kind regards O

Not a huge deal but after using the device discovery it would be nice to select 50 or 60 of the few hundred devices and have KEPServerEX do the tag generation on each vs going into the properties of each and then using the create tags option over and over.

In our project, we have planned to add lots of devices and also plan to add all the associated tags which would mean adding the tags 1 by 1. I was going through the automatic tag generation option but even after I click on 'Create tags' in 'Tag Generation' option, nothing happens. How do I enable this?

Hi, I want to migrate a server. I have 3 servers in the same domain 1 server for WinCC SCADA I'll call AServer B is the standby Server now and is connected to WinCC Server A with OPC DA. and now I want to migrate Kepserver from B to C. I tried connecting Server C with Server A WinCC (OPCServer.WinCC.1) while Server B was still connected to Server A. the entire setup is the same as server B.and, from server C, I can scan all tags from server A WinCCbut it takes 1-2 minutes for this pop-up appear. when I try to open quick client, the quality is always bad, and sometimes "out of service"and there is a message said "Failed to establish callback......" Is there a possibility that the WinCC Server from server A can only connect to 1 Kepserver with OPC DA? 

In the projects property editor you can add a description and a title but they are not shown in the project tree. 

Network adapter is not shown. So getting BAD in client file.    Following action also done but still not showing it. Start the server_config.exe as Administrator Go to KEPServerEX 6\server_config.exe > right click Properties > Compatibility > Change Settings for all users > Run this program as administrator > Enable.     Please suggest what to do for Quality as good in client file 

Has anyone tried connecting to the A/B Powermonitor 5000?  The Rockwell manual says we can configure RSLinx as a SLC5/03 as it supports PCCC addressing.  I tried SLC5/05 in KepwareEX and this didn't work.  Neither did the PLC-5 family,  Thanks        

Hi,Does KEPServerEX support integrity with any hardware security module? 

Hello,  I am reading Channel.Device.System*_Error tag via OPC DA Client of the SCADA. I am able to read tags of the device but can't read the _Error tag and quality is bad, whenever I restart the kepserver computer.After started the quick client I can see the tag quality is good.Why this is happen? Thank you in advance.

So I'm tasked with resurrecting neglected OPC connections and I'm encountering a situation where i have to use a custom interface design XML file with KepServerEX 5.12.140.0 to specify tags from Sartorius AMBR systems. I'm also encountering an issue where the OPC UA Configuration Manager that came with KepServerEX 5.12.140.0 seems to be creating a bad URI that can't be parsed by newer software because it puts whitespace in the URI string?'C:\Program Files (x86)\Kepware\KEPServerEX 5\plugins\connection_sharing.dll'. Reason: 'Connection sharing plug-in failed to load due to lack of driver support.'am also encountering the following error "Unable to load plug-in DLL  Wondering if an upgrade to 6.5 will solve my problems or if i need a more expansive license key or if i should be looking at Kepware Server instead: if there's a driver OOB for KepServerEX if i just get a different license type that will allow me to use drivers and not just a CID XML file. Or if I upgrade

If my KepServerEx V6 instance has two separate network connections to a pair of EN4TR com cards in a CLX rack,  This is to give me redundant com paths to the critical systems. Is there a way to configure them in a redundant\failover architecture within KepServerEx? I know this can be done with an external router but I was hoping there was a native solution.  

Greetings, I know nothing about kepware, other than it gets data from my PLCs for me.  i dont setup the topics, i pretty much never get on the server.  not my job. However, i am having trouble getting info from an oracle database, after having what i think i needed installed on the server.  There were some OPCDB addons or something like that, as well as upgrading oracle on the server from v12 to 18 maybe?  I got the user and password from our IT folks. I can connect to and see the columns i want to pull the data from, however when i try to actually pull data, i get the error attached.  i asked our IT folks and they said i had the correct login info to read from the oracle database and they suggested i get on here... I program PLCs, so i may not understand what you say, but hopefully i can show it to someone who will know what to do with it

Hello,I am involved in a project requiring integration between our MES system and an ECU, where the primary communication challenge is interfacing via CAN Bus. Our objective is to supply test criteria to the ECU and capture the results directly into the MES system VIA KEPServerEX 6.Given our constraints, we are considering using gateways that can convert CAN Bus protocols (CAN 2.0a/b and CAN/J1939) to more common protocols like TCP, UDP, or OPC UA. I am concerned about the reliability of these gateways, especially since many are from lesser-known vendors with limited reviews.Does anyone have experience with such setups, particularly with CAN/J1939 to TCP or UDP conversions? Are there specific gateway brands or models you would recommend? Additionally, there are mentions of MODBUS to CAN Bus conversions in some threads, but details are scarce. Can anyone shed more light on this option?Any insights, experiences, or recommendations on gateway configurations and best practices would be gre

Hello everyone,I am trying to use Kepware Ex Datalogger with FloatArray type.I have selected all items from the device into datalog configuration in Narrow Table Format. When I trigger my DataLog, It only logs data for tags other than Array type tags and I get below error in Kepware. "Error Data Logger Plug-in Unable to query recordset on Log Group 'DataLog_abc_Profile'. Reason: String data, right truncation" I have not configured individual elements of Array type tags rather I have selected direct tags' name in datalog items. Is my configuration OK or I will need to configure individual element for data logging?

Hi, This is Sai Ram Choppavarapu, We are facing an issue related to kepserver license activation with Mykepserver credentials.Same credentials are working for eSupport but not for Mykepserver. Tried to change/forgot password but new password also not working.Getting an error "Your login attempt has failed. Make sure the username and password are correct". Thanks & regards,Sai Ram Choppavarapu.

Good morning, I would like to create a tag, mentioned boolen type flip-flop, which the automation will set to 1 and I would like Kepware to automatically and immediately set to 0.In this way I can alert the automation when communication is missing.I found a thread that covered a similar, but still unresolved topic:Solved: Disable tags when PLC is offline and re-activate w... - PTC Community Thank you.

After computer reboots client connection to the OPC UA is refused until service is restarted.  Issues with service starting and accepting clients after initial computer starts for the OPC UA end point.  Once services are are restarted client connections work great.  However, we are unable to figure while after computer reboot / startup our client connect is refused until restarting service.  We have use KEPServerEX v6.5.829 as well the latest KEPServerEX v6.16.203, these versions have not resolved the issue.  

I try to make a connection with a Rockwell SLC over DH485. For this connection I use the controlox ethernet driver. In RSlinx there is a topic made for this connection with the following path: ip-adress\Backplane\4\Channel\14\DH485\3. We want this connection in kepware instead of RSlinx, how do i do that?

Hi, I'm wanting to use KepServer as a way to expose an OPCDA device via OPCUA. I can connect to the device's server using Quick Client (and other clients), when its configured in KepServer I can browse and import tags but then KepServer fails to connect at the last moment. . .  Screenshot: 1) Quick Client Happily connected2) Config in KepServer3) Failure. . .   Any help appreciated.

Hi, Can I get collect data (the last row) of an auto-update CSV file with KepServerEx?The auto-update CSV file will add another row of information after a cycle time that machines runs.For simulation, I have tried Advanced Simulator where I read from another article. However, the result is not what I expected.It can read CSV file but while I open OPC Client, I cant config my CSV to add a row which makes it look likes an auto-update CSV file (it says the file is using for another process).Do you have any solutions about it or I have to convert the data in my CSV file to a database then use ODBC Client to read it?

I have been pushing data from KepserverEx through an IoT gateway out to Splunk. The data tag name from Kepware remain pretty simple. However, when the data is pushed through the IoT gateway, the tag out includes the device, channel and original tag name. This causes unnecessarily long tag’s to appear in my splunk charts and confuses people who don’t know why that information is included. Is it possible to change the tag name and remove the long name that appears in the code for my splunk charts?

Is there a way to update certificates through an API service for Kepware?Or another way to automate this?

As discussed here.   We are also using two KEPServerEX. One for Development and another one is dedicated to Production. Many of the times, we do not get data from some devices due to that.How can we solve this issue? Can we create an OPC connection between the two KWPServerEXs so that we can get data from devices in Development KEP without hampering Production KEP? --> can OPC aggregator be a solution in this case? If Yes then How?  

I have a device called EWON that send data to kepserver. Now I want to connect another Kepserver to that same device. Will that be possible? And after connecting I get error message as Date Time Level Source Event10/28/2021 10:16:58 AM Error KEPServerEX\Runtime Attempt to add item <device> failed.10/28/2021 10:16:58 AM Error ThingWorx Native Interface Error adding item. | Item name = <device>. Is that error message related to my query?
