Kepware

Hi,   We will be using a cloud set up where Kepware will be running on edge device and Thingworx connected to it from a cloud platform. So our IT team for setting up security and firewall, wants to know what communication protocol is used between Kepserver and Thingworx.     Regards, Sri1

there is a data stream from the robot. the data changes, but the data in the stream is not updated. how do I make the stream auto-update?

Hello   I encountered this problem more then once.    I setup Kepware to connect Thingworx via named IndustrialThing name for example "conn". And i save this created Industrial Connectivity Thing to fetch remote tags and bind them to our properties. The method i use is to create a Remote Thing manually and Add IndustrialGateway ThingShape to add IndustrialThing property to the thing. After that i manually add "conn" to property. After saving the Thing i can do Manage Binding to bind remote tags to my property.   After using this method for 4-5 months on a company, Kepware start to give error to "Connection to ThingWorx failed". After that, I try everything to fixed that but nothing seems to solve these issues. The only workaround i did find is renaming the "conn" IndustrialThing name from Kepware.  For example, I renamed "conn" to "conn1", Kepware is connected to Thingworx. But I have to save this "conn1" IndustrialThing and change IndustrialThing properties to

I'm trying to setup DCOM consiguration as explained in section 4.1 Configuring the Application at https://www.kepware.com/getattachment/04042e47-c690-467c-a931-a1ca126575db/Remote-OPC-DA-Quick-Start-Guide-DCOM.pdf But, I don't see entry on "OPC Server". Because of that, I can't connect to Kepware OPC server from other machine.

Hi in KepServerEX6 I created a channel ODBC Client to get data from a Access database. I created a Device for a table and successfully generated a tag. Now I would like to get data from other tables. I created another device (correct ? ) but the tag generation return error "Unable to generate a tag database for <MY DEVICE>:Automatic tag generation for device <MY DEVICE>' refused due to active client connections" I read another topic , same error. The suggestion was to 'Close all OPC client connections to the device and retryAutomatic Tag Generation' but how can I verify the open connections and close them ? Many Thanks  

Hi, I had come across a project where a seperate server was allocated for Kepserver alone. My queries: 1)Under what case  or architecture is this setup required. 2) Is it some sort of best practices. 3) And what should be the server configuration (cpu, RAM... etc) required here.   Regards Sri1

Hi,    Because of the problem https://community.ptc.com/t5/ThingWorx-Developers/ThingWorx-IndustrialGateway-cause-delay-of-the-data-tag-in/td-p/678674  I'm currently facing ,   I wonder  if  it's  possible to write and poll data tag of Kepware from ThingWorx without using remote thing ?    Regards, Sean

Hello,  I have followed this guide : https://developer.thingworx.com/en/resources/guides/connect-kepware-server-thingworx-guide/connect-foundation I can't connect Kepware with Foundation.  Kepware logs tell that the host could not be resolved.  I have the trial version of Fundation.  "Error ThingWorx Native Interface Connection to ThingWorx failed. | Platform = pp-2009221255A9.devportal.ptc.io:443/Thingworx/WS, error = the host could not be resolved."    I have no clue why. I did create an app-key, with no ip restriction, i'm HTTPS with Fundation... cf screenshots below    PS: i have the same problem connecting Fundation to Azure. 

I am aware of the Thingworx Sizing Guide, but it does not address the size of the KepServerEX hardware.  This reference shows the size of the KEpServerEX used, but no information as to how it was determined.  Is there a document that provides that information?

Hi, I am trying to connect Kepware Server to thingworx Fundation. I am able to establish connectivity between Kepware and TW fundation however, when I try to read tag it says "Tag not connected"   Any advise 

(This problem has nothing to do with Manufactory Apps ,  and probably even has nothing to do with Kepware, Please DO NOT move it to that area)   Hi,  I have 2 channels in Kepware and each channel has a device.  The data tag get updates well when both of the devices are on,  but once one of the device get shutdown,  the delay of the data tag of the other device becomes immediately obvious.   And if set the shutdown device to "simulate" mode,  then the delay of the other device become good.     Since the devices are in separated channels , they should not have impact on each other.   But the IndustrialConnection  is shared,  would be the problem caused by IndustrialConnection ?   Like , the remote thing of ThingWorx keep sending heart beat request to IndustrialConnection  and the request queue become too long if the device get shutdown, which cause the delay of other device  become lo

Hello, I have a variable on kepware of a setpoint value that is sent to thingworx only on the data change. This variable can remain fixed for days but I need to view daily trends with related reports with this variable. Is it possible to force scripts that, once a day, this value is still written to the database even if it has not changed?

while configuring kepware to thingworx we are facing error "the connection requires a valid trust store, but the store is empty or invalid." here is attached snap of property I have checked application key is valid and having date of expire 2022 We have not configure SSL but still its throwing this error.  

i couldnt connect to my printer through kepserverex using modbus TCP/IP Ethernet. please guide us regarding this query as soon.  

 Hello, We're currently using KepServer for all of our machine and database communication, paired mostly with Mitsubishi Q series PLC.   I'm more familiar with the Kepware functionality than I am with the PLC ladder logic. Is it possible for me to continuously write a tag to an M bit on a machine from Kepware, and in the instance that say the server running Kepware is restarted, that tag value would return false? I think it may be more on the PLC logic side, but I was wondering if it'd be possible to use a linked tag that's always on, and link it to an M bit, turning that M bit on, and have the plc logic to try and turn it off. Is there a better method to achieve what I'm thinking in my head?

Hi, I can implement customized device data transformation using Java SDK/Protocal Adapter Toolkits/EMS  on the Edge side before sending data to Thingworx Server.    However,  Kepware connects to Thingworx directly and it seems I can  only implement the data transformation in Thingworx server (except using the advanced tag of Kepware) .  Is it possbile to implementation the transformation of Kepware data tag in Edge as well ? (It is best to use JAVA) .     Regards, Sean  

Hi, I got a very strange phenomenon.  I have a remote thing which is bound to the data tag of Kepware, when kepware detect the change of PLC,  the data change event of the property in Thingworx will trigger the subscription to update the same property, but it doesn't take effect , the property in Thingworx still remain unchanged ,  and there is no error found.  But if manually change the data tag in Kepware or using timer then it works.   In a summery :  PLC -> update Kepware data tag -> raise data change event in Thingworx -> trigger subscription -> execute sync service to update the property value  ==>  does NOT work . no effect   manually update Kepware data tag -> raise data change event in Thingworx -> trigger subscription -> execute sync service to update the property value  ==>  works   PLC -> update Kepware data tag -> launch a timer to poll the property value

Hi,  I have a remote thing bound to Kepware in Thingworx.   The data type is String in Kepware ,  it works well if I write number or english alphabet,  however ,  if write chinese character then it become garbled in Kepware , please check the attached picture .     If I set chinese character in Kepware directly,  then Thingworx can read it and display correctly.  Only write has problem.    Any idea about it ?  Thingworx 8.5.2 Kepware: KEPServerEX 6           Regards, Sean

Hi,    When creating a thing under Industrial connectivity manually:  If there's a few properties(less than 10), it work well. the properties get tagged data from Kepware  without problem.  But ,  If increase the count of properties, for example 60 properties in my case, the properties are not connected and display "?" ahead of the property(see the attached picture).   And  it won't be solved by restarting Kepware only ,  I  have to restart Kepare and re-click Save button in Thingworx , then the connection will work .   Is  this a  designed behavior ?     The problem only occurs on manually creating thing under industrial connectivity,  if create the thing from the binding remote Kepware thing,  then it won't occur.     ThingWorx:  8.5.2 Kepware: KEPServerEX6 (unlicensed , need to restart every 2 hours)   Regards, Sean    

I'm looking into communicating with a Turk RFID Module for OPC-UA  https://www.turckbanner.my/en/product/6814126   Does anyone have experience with use of Industrial Connectivity Kepware OPC-UA and the AutoID Companion Specification?   Any experience or general thoughts? Any known pitfalls with either Kepware OPC-UA or working with the AutoID specification?

Hi, I just started with Thingworx Industrial Connectivity 8.4.66. But I am getting alerts on my PC that there are some time-limited features. Is there a way to get rid of them, not by turning off the notification on my PC?   Thank You! Naeem

I have Thingworx and Kepware installed on the same server, but Remote thing is always disconnected when trying to bing a kepware tag in thingworx via the industrial gaeway   Re:  post
