Kepware

Hello, is there a way to disable the certificate verification on startup for Kepserver 6.8 so that I will not get error message like this "The UA Server certificate is expired. Please use the OPC UA Configuration Manager to reissue ... "    

Hi, I am currently configuring some Advanced Tags in Kepware and I would like to round up some of the values that come up from the machines. For example, if it is 35.5 , round it up to 36 and ranging from 35.1 to 35.4, round it up to 35. Is there a way to do it? What we are looking for is a function or formula to round up a number with standard procedure.When it is 35.5,35.6,35.7,35.8,35.9, round it up to 36.When it is 35.1,35.2,35.3,35.4 , round it to 35.

Hello community,     The Data Logger poped out a warning window showing "unable to retrieve column information" when I was setting up the column mapping for a tag. My ODBC data source (32bit) had been configured and tested successfully, so as the target table in the database.  I tried reinitializing the enviorment and reconfiguring the data source but did not make any progress. The snapshots are attached below. Any suggestions are welcomed and appreciated.     Thanks again for your attention.      

I tried to install kepware edge on an EC2 instance. But the error message shows 'command not found'. I tried multiple variations of the command by just using the filename, or the file name with location, but the error persists. The command for getting the CLI which is this command+ '--help' also shows the same error.   Are there some other steps to install Kepware Edge on an EC2 instance (I have already installed default-jdk and lsb)?    

Hello community, I hope you can help me. I am trying to connect Csense with kepware (6.4 version) with the block "OPC Classic Client source" I have made the configurations both from GE and kepware as is, enable port 135, DCOM settings, but I still do not connect them, for the moment I just want to show both a graph in real time in conjunction with its historical. I am getting all the data from a siemens 1500 plc. If someone has done something similar I hope you can support me. I remain attentive to your comments. I attach images.

OPC Software: KEPserverEX (Kepware OPC server software) Third party software: VB6.0 (Visual Basic 6.0) (OPC Client)   There is a channel, device and tag items are available in Kepware OPC server and would like to read value of OPC tags into VB6.0 software using OPC DA or any other easy method. I would like to read/write value of OPC tag from VB6.0 software. Could you please help me providing the source code and supported files so that I can assemble in my computer without any issue. Thank you.    

We are working on a scenario where we need to provide one set of two redundant OPC UA Servers that act as a proxy between our customer's system and multiple individual sets of redundant OPC UA servers.Because I do not have experience with connections to redundant OPC servers and OPC UA itself, I am not sure if this is at all possible and which packages I need for this. I tried contacting local system integrators as well as PTC itself, but I'm not getting any response. My hopes are therefore on this community! Any advise is much appreciated.Secondly there is a note from the customer that mentions functionality that is easy to understand and makes sense in a way, but it not mentioned anywhere in documentation: Buffering shall be turned on for the proxy OPC Servers to ensure that data collection continues when connection with the customer is lost. All buffered data will be transferred when the connection is restored. Check and confirm buffering duration. Is this at all possible

Hi,   What is the maximum number of tags that can be configured against a single kepserver instance in a Server without any performance issue? I know the number of channels and devices are depends on the driver used. but my question is not about it. It is all about total number of tags per single Kepserver Instance without any performance issue. Your answer will be highly appreciated. Thanks. Below are the system scenarios.   1) Only Kepserver is the application running in the server except other Windows OS service. 2) Using One device per single channel configuration.  

Hello everyone, currently I'm exploring the uses of kepware server ex.Kepware I'm using is "KepserverEx V6.13 "(trial).   My problem is i cannot able to access my tags in Quickclient window, its completely empty(yesterday things were showing perfectly). I'm attaching the screenshot here.         However, if i try to add tags manually, it still doesn't work. Tags do appear but 'cross' sign inside it.   I don't know whats the problem here. Is it kepware(trial) version I'm using or something else. Guide me.   Thanks in advance...  

In my current scenario I have 2 OPC servers (KepServerEx 6.9) collecting data through the Modbus driver and making this data available in OPC UA and DA.Generally, client applications do not have redundancy tools and only my OPC01 server provides data for this type of application.Contrary to this, Osisoft PI already has a tool in its implementation that allows switching between data sources (OPC01 or OPC02).Through the video https://www.youtube.com/watch?v=vaoKidtZ82w I realized that it would be possible to create a Windows cluster to solve this problem and create a redundancy between servers.However, I did not find documentation/guide on the Kepware website that directs me to this type of implementation.Is there any? Could you refer me?PS: I'm familiar with the "Redundancy Manager" solution, but I'd rather point to a cluster than purchase additional licenses for each of the client applications.

Hello, I want to read data from Modbus PLC, so in the Kepwar device tag, there is a string data type. how to use that. my use case is to read the Device name from Modbus PLC and that data push to thingworx, I have connected kepware and thingworx but I want to know how string and other data type work, other than Word data tyepe

Dear, I am evaluating Universal Device Driver (UDD) for one on-going project using socket TCP communication. I can find some examples of the profile files from following github link.https://github.com/PTCInc/Universal-Device-Driver-Examples I also studied the video tutorial from following Youtube post (Getting Started with the Universal Device Driver). But the example (openweathermap api) doesn't work.https://www.youtube.com/watch?v=RGWTfE3Yg4Y&t=5s So can I find other detail tutorial, then I can build up an end-to-end example? Thanks   

Hello, we do a lot of development on an Allen Bradley PLC and had the question come up wondering if there is a way to read or write to the Device Level System Tags (the ._System tags) that you see in OPC Quick Client. Are there any examples or is there a way to do this? This is a 1756-L72 ControlLogix 5570 with revision 32.11 and using KepServerEx v6.10.659.0, basically the thought is can I create a tag in the PLC that can write to or read to a particular ._System tag? Or anyway to read all of the ._System tags on the PLC side?

Hello, I am quite new to using Kepware so sorry if there is a super obvious answer to this question. What are some ways a PLC can know that it has lost connection to Kepware? In one of my projects we created a handshake between Thingworx and the PLC to ensure that the PLC would know that the data had been saved on the Thingworx side.I also read about some OPC UA status codes that should be sent if the connection is lost.Is this what should be used? I have tried to find some information about this on google but haven't really had much luck, so any help would be highly appreciated. Thanks,Jens

Hi,We are attempting to activate new license based on updated sales order, but license generation is not working.During activation process, there is now a prompt window to enter credentials, which didn't happen the first time. Team is continuing to see this. Requires input for credentials, but the credentials we have on file are not working.Team has also tried to create a new user under the administrator group, but we are still unable to log in. 

All, I'm trying to clarify the terms of the Export Agreement.My company recently purchased several licenses for Kepware to be used on a project in Spain.Given that it is being developed in the United States we purchased our licenses here.The agreement states that...You will not re-export or divert any PTC software or technical data relating thereto to any third party or region and you agree to not distribute, any software, technical data or any products derived from software or technical data provided hereunder in contravention of U.S. law or regulation.Are there any issues with the route we have chosen of purchasing here in the US to be shipped to Spain? 

Hello, I have and old Kepware installation that uses OPC DA to communicate with tags in Wonderware.  I am trying to update from OPC DA to OPC UA.  All was looking good; I was able to install the OPC UA Client driver, configure it, connect to the Wonderware server, and read all tags with good quality.   The problem is that I cannot write to the tags. The tags are configured to be read/write in both Kepware and Wonderware. However, when I try to use the OPC Quick Client to write to any tag the following entry appears in the KEPServerEx log: OPC UA Client Async Write failed for 'ns=3;s=1510:IMIS.TAG1.Value' on device 'WWChannel.Wonderware'. Callback item error: 0x80004005. I have tried turning off the firewall but had the same results. From what I could read about 0x80004005 there is some resource that cannot be accessed but it is unclear which resource. Does anyone have experience with this error or have any suggestions on what to try to resolve it?&nbs

Hi, How can i get the data from Brother CNC(Japan), Cat No: TC-S2DN/TC-S2DN-S/TC-S2DN-O. Thanks!     

Hello, In Kepware ( KepServer Ex 6 server configuration ) what is the suggested Device level scan mode? What settings are appropriate to scan 1000s of tags under each device ?   Request all data at Scan Rate Vs  Respect Client Specified Scan Rate For example , In our production system   I observed that "Respect Client Specified Scan Rate"  scan mode some opc tags are bad eventhough they are good on the source server side . After changing to " Request all data at Scan Rate",  most opc tags quality went from bad to good .    What are the pros and cons of the above settings on overall impact          

Hello, I have few questions related to OPC configuration in Kepware. Appreciate your answers1. In kepware , Are there any ways to specify/customize the deadband at Tag Level? ( currently deadband property is on the group level )2, For float data type , what is the max precision available . Is this configurable . Currently, In OPC Client I see only 3 decimal places ( example 10.213) 3.If the poll/exception update rate is 1000ms and MaxItem per Read is 512 ,  are all the 512 tags updated every 1000ms in that group? . What if there are more than 512 Tags in that group?Thanks in advanceAnbu veerappan
