How to include custom string under the values. Example:{|#each VALUES|"variable": CONSTANTSTRING,"|TAGNAME|_realvalue": |VALUE|,"|TAGNAME|_quality": |QUALITY|,"|TAGNAME|_timestamp": |TIMESTAMP|,|/each|}

Trying to pull data from an AB Plc using Kepware without having a TAG in the Kepware Database.  Looking for a way to just pass-through the READ request.  I know the below code snippet works just fine, however, the tag "YourPLCTag" needs to be in Kepware DB.  I just want to access "YourPLCTag" without the tag being in Kepware. var serverUrl = new Uri("opc.tcp://localhost:4840");// Connect to the OPC serverusing (var client = new OpcClient(serverUrl)){client.Connect();// Read PLC valuevar nodeId = "ns=2;s=YourPLCTag"; // Replace with your PLC tagvar value = client.ReadNode(nodeId);// Do something with the value...client.Disconnect();}

Hi everybody, Assuming that I have a configuration of one machine in one channel.What is the optimal number of channels on KepServerEx? When should you think about turning on a second KepServerEx server?how to distribute overload on one KepwareEX? Is a Master/slave hierarchy recommended for several KepServers at the same time?Thank you for answers.  BR,Jan

Hi, Is it possible to rename the OPC server without altering it through the ProgID, such as by modifying registry settings?I am seeking this option because I have a program  that fails to recognize the redirected ProgID. Consequently, although the OPC Client can see the tags, the program cannot. The necessity for changing the ProgID arises due to a server migration; the tags are originally configured with KEPServerEnterprise version 5, and I am currently in the process of migrating to version 6. Thanks in advance

Hello everyone. I am an Apps. engineer from South Korea. I would like to know how to connect OPCDA to InTouch through KepServer EX as an OPC server.   We would like to build a connection between our own PC to customer's own HMI (InTouch) to send some data from ours. Our software has OPCDA Client, so we would like to put KepServer EX into our PC to overcome OPCDA's COM/DCOM barrier. Once our data is collected in KepServer EX, we would like to send this information to InTouch, so the user can monitor the data through their system. Is it possible to build connection like the info. above through KepServer EX as an OPC server? If so, it would be helpful if you could provide us a guide line or manual.   Thank you.

Dear Community,I've got a problem on my hands with the KepwareServer Ex Ucon-Driver.The driver can't recognize the string I got from a device - this message pops up.in the communication logs I can see that the machine communicates; The Read-Response transaction is set to "terminated by stop characters" which are "SP""CR"EOT", which are also the received characters. Despite that, the driver is not recognizing the characters?"Frame has a known length" also doesnt work, despite getting the right frame size from the machine.I am using Ethernet Enc. over a MOXA converter to get to the machine - when I used a virtual serial port, it worked, but was a lot slower. Kind regards,Kepware User

Hello community, i used emergency license before my server Raid failure, Is it possible i can use again the emergency license and back system online?

Hi,   I would like to create local tags to receive the output of Link Advanded tags. The purpose is to synchronize the timestamp of several data with a trigger. I did it with Derived tags - Trigger but when the valueof a tag doesn't change, the derived tag is not updated with the trigger occurs. So my OPC Client doesn't see the new event.   Thanks in advance.

Derived tag: Addition is valid but subtraction is not? PTC support acknowledged this back in August but refuses to respond to my ticket. Screenshots attached..

Tag XX on device XX.XXX was not imported . Item Failed OPC server validation.When i created new project in Studio 5000, I am able to browse the tag. But when i tried to browse tags from Control Logix PLC program provided by customer, gets above error. 

Dear member and adminWhat kepserver version which has multiple column mappings editing and also Siemens S7 PLus connectivity feature? I'm check V6.5 has feature multiple columns mappings editing which i can delete Itemid, Numericid and soon which i don't need but it doesn't have S7Plus connectivity.While in V6.13 it doesn't have multiple columns mappings editing.i need feature multiple columns mappings editing otherwise is painstaking job to delete one by one. 

Hello  ,   we had scenario in Kepware server  while connecting to OPC UA connection , whenever  your machine get offline and then again machine get online , we don't get the data , we had to reinitialize the server .   who can we automatic connect to the machine after the machine available (online) ? In Kepware server to OPC UA .  

I have a JSON project file. I want to import this file to KepServerEx. What steps should get followed? Need help over this topic. 

We observed there is delay between Tag timestamp and current time, to study on this we need to calculate the delay between these two timings. How can we achieve this using advanced tags in Kepware. 

Is there any security mode in Kepware? Is there a document talking about kepware security?   Translated by the Community Moderation using Google Translate ----------------------------------------------------------------------------------------------- Há Algum modo de segurança no Kepware ? existe agum documento falando de seguraça do kepware

Am I able to install KepserverEX on an Azure server and connect it to a PLC on a network at the factory? I'm using the Modbus TCP/IP Ethernet driver specifically. The PLC will have an internal IP address (e.g. 192.168.1.2), but that is not the public IP address. If Kepware is outside the factory network, then I'll need to use a public IP address when I configure the device, but then I don't know how to direct the connection request to the correct internal IP address. I've seen some questions about using ThingWorx to connect cloud and on-prem systems, but not KepserverEX. Do I need to use ThingWorx to do something like this?

I'm trying to use a Derived tag to compare a string tag to some static strings and return boolean response for if it matches or not.  I was hoping the logic operator == would do this like it does for numerical values but expression validation returns "String tag expected".  Is there another logic operator to use to compare string values or do I have to do something different? Using KepServerEX 6.14 Thanks!  

Does the operation of PLC continue normally?Considering I imported around 1500 or 2000 tags from different PLCs, how is the impact of the network?         

Hi, I am having a Manufacturing Suite License and it was working great till some days before when I tried to configure Alarms and Event in Kepware Ex 6.14. Just after trial, I removed the configuration in Alarms and Events tab, but still I am getting the message pop up: One or more feature is time limited... I have disconnected and Re-Initialized, even restored old configuration backup, but still it keeps on Popping up... 

How did the Tag Import route work for you @BM_9155657 ?  Did you find a better way?   Reference topic - https://community.ptc.com/t5/Mfg-Solutions-Apps/How-to-avoid-importing-all-tags-when-creating-a-device-in/m-p/794517#M2464

Hi,We are checking the possibility of using KepserverEX as connector for several factories containing machinery of different OEM's, and several data-protocols (MTConnect is the most common). In testing we came across a potential blocker. We are currently relying on some attributes commonly implemented in condition-type dataitems within MTConnect, namely "nativeCode" and "nativeSeverity", but it doesn't seem like these attributes are being picked up by MTConnect driver on triggered conditions? I am using KEPServerEX v6.15.132.0 in combination with MTConnect driver, and I'm relaying the data through IOT Gateway to an MQTT broker. Is it possible to pick up and relay nativeCode and nativeSeverity attributes somehow and send these along with the value through MQTT?  

Good day! I have a use case where I must take some OPC-UA tags and send them to a REST server which is then connected to another OPC-UA server using ThingWorx Kepware Server on both sides. Here is what my configuration looks like:- ThingWorx Kepware Server on Remote PC configured as a REST server. This REST server is bound to one FLOAT type tag on a test OPC-UA server. I can read it and write to it just fine using powershell and my web-browser.- ThingWorx Kepware Server on Local PC configured as a REST client. The REST client points to the REST server configured earlier and reads one FLOAT type tag from the source OPC-UA server (production data). The idea is to publish this OPC tag to the REST server earlier (which should then automatically update a tag on the test OPC-UA server it is bound to). I tried to do this using the Standard Template in the REST client's message body but I keep getting ERROR 500. I can use the Advanced Template like this and it works but the value is

how are you?I want to use simulator ( type of channel) send data to our company app.what should I do at kepserverex? 

We have a customer who has a number of RTUs on a GSM network. They current use a proprietary protocol to communicate with the RTUs - This protocol supports retrieving buffered data from the RTU after a communications interruption, but it does not have any security features like encryption or authentication. The RTUs support OPC-UA, so the customer wants to switch to using OPC-UA for the security it brings, but they also want to use the Historical Access part of the OPC-UA specification, to retrieved buffered data. A colleague of mine previously used Kepware as middleware between a DNP3 RTU and a SCADA that used OPC-DA - in this solution Kepware was able to backfill buffered DNP3 data coming from the RTU into the SCADA (over OPC-DA).Could KEPServerEX be used as middleware as follows:RTU ---(OPC-UA Historical Access)---> KEPServerEX ---(OPC-UA Data Access)---> SCADAIn other words, could KEPServer, retieve the buffered data from the RTU (OPC-UA HA) and backfill it into the
