Kepware

I can't seem to consistently get the Read/Write Default User Account when I need it.  Any thoughts on what is grabbing it or how to find out what User has it?  Much less a way to boot them off and wrest control.

Thingworx: 9.3 KepWare 6.18Some Industrail Things can not connect to KepWare. The Industrial Gateway is set. All other Things are receiving data and everything is fine. Only 5 assets won't connect again. 

Hi ! Does anybody read tags from GE Quickpanel+ ?Which drivers we should use ? GE Ethernet ? What model ? PAC Systems ? We have downloaded runtime HMI project (Proficy Machine Edition 10) on GE Quickanel+ 755xxx. But we have no source project. We can read OPC tags from panel via Proficy View OPC server.  Used fromat is STATION IP\NameTagIs it possible to read tags via Kepserver OPC ?

Hello, I am a new user to Kepware, I setting up a flow of SQL data -> Kepware (querry to json) -> IoT gateway (REST server).Although the data in the OPC quick view look fine (attatch picture), the output from iot gateway contain un wanted character, how do I clean that ? { "readResults": [ { "id": "SQL2JSON.SQL2JSON.JsonData", "s": true, "r": "", "v": "[{\"id\": 1, \"pressure\": \"10\", \"temperature\": \"1\"}, {\"id\": 2, \"pressure\": \"190\", \"temperature\": \"1\"}, {\"id\": 3, \"pressure\": \"170\", \"temperature\": \"1\"}, {\"id\": 4, \"pressure\": \"0\", \"temperature\": \"0\"}, {\"id\": 5, \"pressure\": \"0\", \"temperature\": \"0\"}, {\"id\": 6, \"pressure\": \"118\", \"temperature\": \"70\"}, {\"id\": 7, \"pressure\": \"118\", \"temperature\": \"70\"}, {\"id\": 8, \"pressure\": \"118\", \"temperature\": \"70\"}, {\"id\": 9, \"pressure\": \"118\", \"temperature\": \"70\"}, {\"id\": 10, \"pressure\": \"118\", \"temperature\": \"70\"}, {\"id\": 11, \"pressure\":

I'm looking into utilizing the Universal Device Driver (UDD) for getting data from a REST API, however the API I need to communicate with is on a secure port requiring https.  I've found two articles that specifically say TLS is not currently supported by UDD:https://www.ptc.com/en/support/article/CS446447?source=searchhttps://www.ptc.com/en/support/article/CS442775?source=searchSince the UDD profile is user-defined, I'm still curious if there's a way to implement TLS into the connection via the Javascript profile.  Here are my questions I'm looking to get answered: Has anyone successfully implemented TLS/HTTPS calls via UDD?How does the back-end Script Engine make the calls to the remote host? Does the Script Engine use a particular library for the calls? Is TLS support on the UDD roadmap?

When using drivers with HMI applications like InTouch or Ignition, the tag in its database could have address modifiers or simply the tag type to let the Modbus driver know that you're looking for a floating point that is using more than one register. It appears that there's no way to accomplish the same thing when using KEPServerEX. Instead of a Modbus driver specifically written for Intouch or Ignition HMI applications.The only option is to manually create tags inside of KEPServerEX and then read those from the HMI? 

Getting below Error   IoT Gateway                 Failed to connect to server: '127.0.0.1:57212'. Please verify this connection information is correct and that the host can be reached.

I have attempted to connect to the Siemens TP900 OPCUA server with kepserverEx and am unable to do so, but I have no issues with the Unified Automation UaExpert application:    With keptserverEx, I follow these steps but am unable to succeed.   As it was not functioning in the certificates, I used the one I had imported Unified for OPCUASERVER, but nothing happened. I restarted the runtime and the server, but it still does not work.  

my KepserverEX lincense is valid but OPC UA trusted Client is expired.gone to the Instance Certificates of OPC UA Configuration Manager and tried to Reissue Certificate in Client Driver.Now I am not able to see  URI in Trusted Client.How to renew Client Driver?

KEPServerEX 6.14 version 6.14.263.0 The problem statement is that I have Modbus rtu communication where Rs 232 is converted to TCP/IP then via layer 3 switch i can transmit the data to my server in DMZ where the data can be checked using serial port utility software but i am unable configure the same in my Kepware software in the same server to fetch the data. Can you please suggest how to proceed further with Kepware software. I am new for using Kepware but could be able to configure other protocols like Modbus tcpip, opc ua and opc da but unavailable to configure the same. Kindly guide me to get the data in kepware. #kepware 

Our Kepware server (v6.16.203.0) is connected with a Siemens PLC 1500 with the Siemens Plus Suite - (KWP-SIEMP0-PRD KWM-SIEMP0-ATT) driver. The PLC has defined a datatype WString of 10 characters long (24 bytes). Which datatype should we define in the Kepware server as the datatype wstring does not exist (only string). When we define the tag as DB1101.STRING0034.24 we receive no error but when reading the value from the plc we get a blank result. If we define as bytearay or hexstring e.g. DB1101.HEXSTRING0034.24 then we get the value of the PLC returned as 000A0000300068000... which seems as the correct hex representation of the PLC value. However it is not clear how to write a value to the wstring. We tried several notations with the Quick client, but always get errors like: Failed on item <tagname> synchronous write.Changing the PLC program or address types is not an option - we can adjust or IT application (=opclient) but need to know how to write to this datatype wstring

Dear ptc communityI am currently using the U-CON driver in Kepware to collect data from a device over UDP (not TCP). The system works stably for the most part, but intermittently, the tag values stop updating in Kepware without any errors or changes in status. The data quality remains "Good", but the values become frozen.To clarify: I’ve verified using both Wireshark and Kepware's diagnostics tools that UDP packets are still being received from the device at the expected interval and in the correct format.Despite this, Kepware stops updating tag values, and there is no indication of failure or timeout within the application.Only a restart or reinitialization of the U-CON driver restores normal operation.The device always ends its transmission with a consistent termination character. I’ve tried both termination-based and fixed-length receive modes, but the issue still occurs occasionally.I would appreciate your help with the following:What could cause the U-CON driver to stop updating v

hi guys, Could you know whether Kepware Server can support communication between Siemens PLC and Siemens Desigo CC via BACnet/IP? Although Siemens provides a BACnet gateway for BACnet integration, its network configuration does not comply with IT security requirements. Therefore, I would like to know if Kepware can perform protocol translation. If so, could you provide a configuration manual? Thank you very much.

When i browse the tags through Matrikon OPC UA explorer, The tag displays all the attributes along with the value. is there any way we can suppress them.  

I have about 30 sensors that support Json Get requests for data but I am struggling to find the appropriate way to get this data and assign it to tags in Kepware. I have found several articles that point to UD or U-CON or IoT as solutions but the articles don't match reality. I have a get request - "https://webapi.ubibot.com/channels/{channel ID}?account_key={27digit_key}" that returns the data from the sensor in a format that will nee to be parsed to pull out certain fields. Does anyone have a good process for this? Happy to provide more info or sample responses if that helps.

Hello, I would like to set up communication between two KEP Servers KEP Server to KEP Server.Currently, the other KEP Server is reading tags from our server,but we are unable to read their tags.Our current license status is as shown below.Do we need to purchase a separate OPC UA Client?If so, how much does it cost approximately?

I activated the license of KEPServerEX. However, this message appears each minute.How can I remove it? 

At the moment Kepserver is only able to publish it's data to a MQTT broker as a json string. Because og this I need an extra software tool to split tags into topics and republish them into a UNS.I need Kepserver to be able to publish each tag on a separate topic for example corresponding to the structure of the tag groups in Kep. Is thes a part of Kepware's reoadmap?  

Our Kepware servers are reading around 100,000 tags from DCS server and forwarding to PI servers. We created one channel connecting to DCS server, and the minimum tag scan rate is 5000ms. The problem is when I meet some problems and reboot Kepware server, the DCS server will slow down for about 10 minutes after the Kepware instance running. We have already deleted 20,000 unnecessary tags, now the number is around 80,000, the problem remains. We also enabled “Read form cache” when start up, but it did not help. Would you please give suggestions on below points: 1. How to proof that it is not hardware issue which caused this problem? What should I check on DCS server side when Kepware server rebooted? For example, CPU load, network load, hard drive load, etc. By the way, the spec of DCS server is i7+32GB RAM+1TB SSD. 2. Is it possible to solve this problem just by changing settings or optimizing tag list in Kepware? So that we have less job to do and less arguments with other teams.

Dear Kepware Team,@bdube@ptc.com I hope this message finds you well.As part of our ongoing efforts to align with upcoming EU cybersecurity regulations, I would like to inquire whether Kepware products—specifically KEPServerEX—are expected to be subject to the requirements of the Cyber Resilience Act (CRA).If so, could you kindly share:Whether Kepware is actively working towards CRA compliance?The anticipated timeline by which Kepware products will be CRA-compliant?Any documentation or roadmap that outlines your approach to meeting CRA obligations?Understanding your position on this matter will help us plan our integration and compliance strategy accordingly.Thank you in advance for your support. Best regards,Mani

I have no problem in reading Kepware simulator from address R0001 (which self incrementing) from node-red, but unable to write into address K0001 or S0001 in node-red. Any advice will be much appreciated ? The moment i started to write, the node-red exited!. ns=2;s=SimulatorChannel.SimulatorDevice.MyWriteTag

Hello. Im wanting to communicate with some ABB totalflow  computers through Factorytalk SE. Do I need just the ABB Totalflow driver or do I need the OPC connectivity suite as well.

I need to transfer a Kepware license (offline)...  1. I created the trasfer_request file on the 1st server... no issues2. I uploaded the transfer_request file to kepware portal... no issues3. I created the activation_request file in the 2nd server... no issues4. I uploaded the activation_request file to kepware portal and everything seems to be ok... I complete the form with the requested information... no issues5. however when trying to create the activation_response file, the file is not generated and google is only redirecting me to a page with the next title "Legal Policies, Agreements and Disclaimers" (see attached image)Please advise... I really need to get the activation_response file in order to activate the 2nd server.

We are working with PLC Siemens S7-1500 Firmware v4.0. OPC is able to establish connection but at some point it disconnects and gives following error: "Device is not responding. Connection closed by device". Slot and rack in configurtion is correct. PLC Siemens S7-1500 Firmware v4.0KEPServerEX version 6.18 Could you please suggest any solution?

Dear Team,We are setting up Kepware to connect to an OPC UA server (e.g., Prosys/800xA) and publish selected tags into an MQTT broker at the Edge (Mosquitto).I see that Kepware offers both the OPC Connectivity Suite and the IoT Gateway add-on. The product descriptions are a little confusing in terms of overlap, so I want to confirm:If my use case is strictly OPC UA → MQTT JSON payloads, is the OPC Connectivity Suite license sufficient?Do I still need the IoT Gateway license in addition to OPC Connectivity Suite for MQTT publishing?Is there any difference in MQTT support between these two (e.g., Sparkplug B, payload formatting)?Are there any tag limits for each of the two license suites ?For long-term production deployments, which is the recommended license bundle for OPC UA to MQTT?Thanks in advance for clarifying!
