Kepware

My system consists of two Control Logix L83 CPUs and one OPCDA server.I use advanced tags between these systems with both reads and writes to all of the devices.The issue I am encountering is this:When we first start up the system, the links do not synchronize between the systems.I have groups of boolean values in the PLC that have a value of 1 but in the OPCDA server, they remain 0.  If i manually change the state in the PLC from 1 to 0 and then back to 1, the OPCDA server will then show the change.I have tried opening the quick client and performing an async refresh of the cache and device but this does not seem to help. Is there a way to tell the whole system to sync up and ensure the linked tag destination matches the source?

Hi, has anyone had an issue with setting up KepserverEX to read the Modbus kWh address 45100 which is a 32bit float on a IEM3255 energy meter?  KepserverEX reads all the other registers such as Voltage & Current registers which are also 32bit float and returns the correct values.  It won't read the kWh value and just returns a Zero, I've tried toggling Modbus Byte Order, First Word Low, Zero-based addressing and all sorts of combinations. I've even set up a dedicated channel just to read kWh in case there are different settings for different registers but no good.I've tried other SCADA platforms such as Ignition and this reads it fine, so I know I've got the right address.Any help appreciated

Is there any way KepserverEx can pull tag from FT Historian?

Hello Everyone,  You know if Modbus Suite has compatibility with Windows server 2022? Regards

Hello everyone, I’m working with KepServerEX and need some help with a tag-based counter setup. I have a single tag, and I want to monitor its value every second. Specifically, whenever the tag’s value exceeds a certain threshold, I want to increase a counter that starts at 0 by +1.Here's a summary of what I'm trying to achieve:Monitor the tag value every second.If the tag value is above a certain threshold, increment a counter by 1.Counter should start at 0 and increase by 1 each time the condition is met.Could someone guide me on how to set this up? Any tips on scripting or configuration within KepServerEX would be greatly appreciated.Thanks in advance!

We have a OPC UA channel created to retrieve tags values from a Fette OPC UA Server. It was working fine until the certificated located in the OPC UA Configuration Manager in Trusted Servers for the Fette OPC UA Server expired. Even if I remove that certificate and create again the OPC UA channel it add again the certificate but with the same expired date.

Based on below document, it seems only Windows Server 2016 ?https://www.ptc.com/store/-/media/kepware-store/en/datasheets/opc-connectivity-datasheet.pdfHow about windows 2019 or 2022 ?  Supported Operating Systems• Windows Server 2016• Windows 10• Windows Server 2012 R2 and 2012• Windows 8• Windows Server 2008 R2• Windows 7 Ultimate, Enterprise, and Professional Thanks 

Looking for a better way to do  bulk import into KEPServerEX. I currently have an Excel  workbook with all the points in the system.I use VBA to create a JSON KEPServerEX application file. This works well for the initial setup and testing.The issue now is that when the customer makes a large number of changes or adds a new block of thousands points to an application we have to restart the KEPServerEX application when loading a new JSON application file. So all the existing points may miss some updates while KEPServerEX is restarting the app. If the CSV import is not very helpful as you would still need to manually create all the channels and devices, then do a manual import on maybe hundreds of devices.  I've not tried using the KEPServerEX API yet but looking at a demo it mostly seemed to give you the same functionality as the normal KEPServerEX client.

Hi everyone,I'm having trouble setting up Kepware OPC Server to read data from my PLCs. My Setup:- PLCs: Use Modbus RTU communication protocol as masters (initiate communication).- Kepware OPC Server: Used to acquire data from PLCs.- USR-TCP232-304 Module: Converts RS-485 communication from PLCs to Ethernet for Kepware to access. (Link to user manual: https://www.pusr.com/download/M0/USR-TCP232-304-User-Manual_V1.0.3.01.pdf)  The Problem:I can successfully receive data using a "Modbus slave" emulator software.However, Kepware OPC Server fails to receive data from the PLCs.My Kepware Configuration:Driver: Modbus RTU Server SerialPhysical Medium: Ethernet Encap.Port: 1123Device 1: ID 1 (matching PLC master write address)  What I Need Help With:Can someone advise on the correct Kepware driver for my setup?Are there any additional configuration steps required for Kepware or the USR module to establish communication?Any troubleshooting tips for Kepware's diagnostic tools to

I have multiple csv files each tied to a different advanced simulator channel. Within each of those channels I have one device tied to one csv file.Each of the csv files is different, meaning they have different number of columns and rows. Each file has approximately 32,000 rows.The record selection interval for all devices is 19200 ms. I noticed after a few days that the programs were on different lines of each csv file even though they have the same record selection interval. I was expecting that they would all be on the same row number because the record selection intervals were all the same. How can I counteract this and what is causing the problem?

Hi Experts,I'm a beginner with Kepware and i've now encountered an issue i would really appreciate some help with solving: In my Siemens PLC i got an REAL variable that has the value "25.999".When i added the tag to Kepware (Float) and launched quick client the value is now shown as 1.10415E+09.How do i get Kepware to show the actual/same value as i can see in the PLC? Thanks in advance! 

In kepware there are energy meters tags showing tag quality good but values are shown as zero. All of changes in setting like reducing block size, recreated channel and devices, restarted kepware number of times we got bad address in block error. kepware error guide saying below reason,Possible Cause:The driver attempted to read a location in a PLC that does not exist, perhaps out of range. For example, in aPLC that only has holding registers 40001 to 41400, requesting address 41405 would generate this error.Once this error is generated, the driver does not request the specified block of data from the PLC again. Anyother addresses being requested from this same block are considered invalid.Kindly anyone post a solutions for the above problem.

Q-series Mitsubishi PLC connected to two Kepservers. One is KEPServerEX v6.14.263.0 and another one is Thingworx Kepware Server v6.14.263.0.I am receiving data from PLC in KEPServerEX v6.14.263.0 but not in Thingworx Kepware Server v6.14.263.0. all the channel and device configuration is same.Communication is having TCP connection and port number is 10000 in mitsubishi PLC and same at server side.earlier I was able to receive the data in both the servers.How can it be resolved?

We are getting "Request pending" from Kepware IoT Gateway REST Server.We have configured almost  - 10000+ tags for each site. We have CPU utilization remaining below 30%, indicating sufficient processing capacity for additional tasks. Network bandwidth is available, confirming that communication delays are not related to data congestion. We have only a single Kepware for all the sites. Does it going to impact our solutions?

Hi all, I am trying to import some OPC UA tags into Kepware via CSV. I have an address that looks like the below which is the address value in my CSV file: ns=3;s="DB31 Data Fixture"."CurrentMoldType" But when I import it the address ends up like this in Kepware:I can't seem to figure out why it is ending up with "" in Kepware when it isn't like that in my CSV

I am using KepwareEx6.15 with Mitsubishi iQ-R32 PLC + RJ71EN71 module.Kepware Channel and Device configuration point out to the RJ71EN71 module (SLMP TCP/IP port)I have created SLMP TCP/IP 40 ports for connecting the same PLC+RJ71EN71 module with KepwareEx6.15 multiple channel and devices for limit the tags in each devices for quick poll. I have active client connections with KepwareEx is 120 and Active tags more than 3000 with scan rate 100ms. I am facing the challenge to write back 200tags values from kepwareEx to PLC it took more than 40 secs.  the below information were my testing observations. Scenario 1: When i restart the Kepware and disconnect the active client connections and maintain one channel & device with 200 tags the write back time is 6secs. Scenario 2: When i restart the Kepware and loaded the active clients connections and maintain the one channel and device with 4000 tags and write back time of 200 tags is 60secs Scenario 3: Whe

Hello, We are working on a project where we aim to collect PhD data using Kepware and transfer it to Apache Kafka. Since Kepware doesn't have a direct integration with Apache Kafka, we designed an architecture where we send the data to an MQTT broker (Mosquitto) and then use Node-Red to forward it to Apache Kafka. However, we're unsure if this is the best approach.We're currently in the testing phase, but as the number of tags increases, we’re encountering some issues with Node-Red. The data is not being transferred properly to Kafka, and we are getting some buffer errors in Node-Red. By the way, we are using Node-Red as a MQTT connector, and while there are many other connector services available, We preferred the open source one.. We are working with approximately 60,000 tags, and our goal is to send the data to Kafka in 1-minute intervals.How can we successfully implement this project? Have there been any similar projects done before? If you need more information about the

Hi Team, I have approximately 2000 tags configured in the KEPServerEX Mitsubishi PLC Channel. When I open the Quick Client, all tags show good quality and actual values. However, I am now looking to write or change the value of all 2000 tags at once, instead of selecting and entering values for each individual tag manually.Could you please advise if there is an easy way to update all the tags in bulk within KEPServerEX or Quick Client? Any recommendations for handling this in a more efficient way would be highly appreciated.

Hi Team, How can we check the number of tags available in an individual device in the attached configuration type.

Hello, I am attempting to create a new channel and I want to define the Beckhoff TwinCAT driver communications, but I do not see it in the list of driver options.  How can I obtain Beckhoff TwinCAT driver? Can it be applied to an existing version of KEPserverEX that does not have it, or does the KEPserverEX software require update to another version? I greatly appreciate the help here, thank you all so much in advanced!

Hi all, I am working on a use case using the kepware API to create kepware tags. Long story short, I want to create many tags with an empty/placeholder address and then can update the address at a later time as needed, but don't know what address will always be there regardless of machine that I can use. When I try to create a tag using the API with an address that doesn't exist it errors, which is why I am looking for a "universal address". I don't have much experience with PLC or address stuff so any help on this would be appreciated. 

Does Kepware enterprise have MQTT Client Driver.Thanks
