Kepware

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. 

While Configuration I gateway for MQTT Client showing error  Failed to create JVM using JRE .Check error image also IOT Gateway configuration. 

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?

Dear PTC Community, My collegue having an error "failed to start runtime in service mode. the service cannot be started either because its disable or has no enable device associated with it"  after adding few points in KepWare OPC Server. Attached image for reference. KEPServerEX 6 Need kind advice from community here that have experinced this issue and solved it.  Thanks,Nu'man

We have program using Kepware software for talking with PLC. But the program stop every 2 hours as described if Kepware is running evaluation mode. But looking into License utility . License = Good  Are there any logs where to see why ? Windows event logs says nothing....

Hello community,I started playing around with KEPServerEX recently (latest release: 6.16).Datalogger is super simple to configure for basic purposes. Now, I am trying to do some advanced escenarios where data needs to be saved using a stored procedure. Is this possible to accomplish?Before stored procedures, I tried using a dummy SQL view (MSSSQL) with a "INSTEAD OF INSERT" trigger in order to mock the idea to write to a single table but that SQL trigger view is not being fired through Datalogger... The purpose of all this is to have a single Log Group that writes to different tables based on a condition that I define. A simple example that passes information to a SP would be:@action=10, @p1="Hello" -> would write to table "Table1".@action=15, @p1="World" -> would write to table "Table2". Cheers,

Hi Community experts, I need to create a Modbus TCP/IP Ethernet channel in KepServerEx6 but I am not getting any option to select the channel. It has only simulator type channel available. Could you please help me troubleshoot how to configure any other channel in my kepware.  Kind Regards,Sid

Hello,  I have this error : Device is not responding. | ID='xxxx(ip of the machine)' but when i launch Quick Client i can see data coming from tags. Anyone can help me with this ? I'm using ThingWorx Kepware Server 6 and this is happening only for machines that use Siemens TCP/IP Ethernet protocol  Thanks 

I need to use Kepware to convert for a unit of measure. That is, if we pack 4 cups on the lines, I want to count the four as one single unit. How can the tool be used to perform the conversion?

Hi all,Been using the Kepware Configuration API for a few weeks and am trying to create tags where I customize scaling values (need to divide value by 10). I try to set:"servermain.TAG_SCALING_SCALED_HIGH": 100 The tag gets created and 201 created message is given, but it still shows the default scaling value of 1000.  Wondering what I am doing wrong here and what else I need to do to get the scaling to set correctly for a Kepware tag from the API.  Any advice is appreciated, thanks!

Our project is considering using KEPServer but I still don't know the process to bring KEPServer from development environment to real use. Please let me know what documents I should look for and where to find this answer. Thank you.

Hello,We need to connect an equipment to KepServer using the protocol ZMQ.Would it be a solution with KepServerEX?Thank you

Hi, I have a Kepserver with some Datalogger sending parameters to SQL,  for some reason at a specific moment one of the Dataloggers stop sending data to SQL buy the others Dataloggers still work fine. all of 4 Dataloggers have the same SQL Database table configured. they were working oks but at some point last week stop working. Any Idea?
