Kepware

Does anyone know if it is possible to read modbus device ID objects using Kepware's Modbus TCP/IP driver? I am referring to the data you access using modbus function code 43 (e.g. vendor name, product code, firmware revision, etc.). I can only find references to the four typical modbus tags types (output coils, input coils, internal registers, and holding registers) when browsing through the driver's manual.

I have recently upgraded old server's ( x2) with new S2019. I installed the latest Version 6.15.132.0 of KEPServerEX and the backup configuration of my existing installation. I have an assortment of ROC RTU's and Allen Bradly Control Logix PLC's. All of the remote devices communicate but one of the PLC's won't update the tags? The configuration file is the same and works on the old installation but nothing will update for this one device on the new S2019's.

When I am trying to publish a simulator tag value to a broker I am facing the below error. Can someone tell me how to fix the errorMQTT agent 'MQTT Broker' failed to process write request on topic '123' - reason: 'Cannot deserialize value of type `[Lcom.kepware.agents.mqtt.WriteValue;` from Object value (token `JsonToken.START_OBJECT`)_ at [Source: (String)"{"timestamp":1704956770208,"values":[{"id":"Simulator.Long.Rand","v":49,"q":true,"t":1704956770198}]}"; line: 1, column: 1]'

I would like to find out if the "Advanced Tags" functionality is part of the Kepware Manufacturing Suite. I can only find the list of included drivers but not whether other modules are also part of the suite. I hope someone here knows. Thank you.

Hello All,  We are moving forward to understand how advanced tags can create value to our DPM and AMU Environment. Lately we have come to the idea that reading the tool life would be beneficial to us. We are using MTConnect protocol to monitor our Mazak Assets.  Checking with Mazak their MT connect code, does not support the tool life, i would like to know if someone is currently monitorizing this information. 

I tried to export the complex tags (advanced tags) created in one instance to other using Export/Import CSV it is not taking the mapped tags within them. How can i get it done with the mapped tags along with complex tag. 

Hello @AB_10607533, we have the same issue you marked as resolved in this thread, we want to read and write inside the address #10095 via the Fanuc Focas Ethernet protocol using the "Open" model. How did you managed to solve the problem? The documentation linked in the answer (link) clearly states that the "#" variables range is limited to #9999: Thank you,Riccardo

Hello! I'm configuring a PLC device inside a local network (a S7-1500 with endpoint opc.tcp://192.168.0.190:49320) and already configured a NAT device to translate the local IP for a public IP at the VLAN (10.10.230.235). From my server I can ping the NAT but when I try to configure it into Kepware (installed at the same server) it doesn't find any available endpoints. I tried also to configure it using "Discovery Server" function. Any ideas in how to configure a endpoint behind a NAT address? Thanks in advance!

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?

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?
