Hi,  i am not able to login to MyKepware portal, alwas getting a message "We've made changes to My Kepware. Please log in again.  Please advise, i have to activate a Kepserver license. Thx.  

Hello,I'm getting this error: Connection not established. Retry ? (you can work offline by selecting 'NO')Data collection stopped for no reason. Rebooted the server and getting this error KEPServerEX\Configuration            Connection attempt to runtime failed. | Runtime host address = '127.0.0.1:32402', User = 'Default User', Reason = 'This operation returned because the timeout period expired.'. Version: 6.7.1067Any ideas ?

Hello, I am trying to configure Atlas Copco Micro Torque MTF 6000 in Kepware and as per device documentation the MIDs for this device are used differeltly than that of full Atlas Copco Open Protocol. e.g.     My question here is, how should I use the MID 008 to read the last torue value, I know that in device settings there is an option to enable the use of generic subscibe which enables MID 008, but what will be the tag address then for torque value? or it will be same "LTR_TORQUE_VALUE". (FYI I am a Thingworx developer & have a limited orientation towards industrial protocols & their working)    

Dear All, I am trying to communicate FX5 with Kepserver, however failing to connect despite different trials. I have set PLC setting to SLMP setting with both TCP and UDP port and set it accordingly on the Kepserver. Still not able to communicate with the PLC with Tags value as BAD.I am attaching the pictures for reference also.  

Kepware server 7 comes with Audit Trail.The Min days to preserver max limit is 90 days. Details on this in the help menu is very vague.Is it fully 21CFR part 11 compliant, if it only preserves for 90 days? What is the recommended method to preserve audit log files indefinitely?and also allow for an audit log report to be generated.   

Hello,I have wonder, does kepware datalog driver has any custom data logging parameters ? for example I want to log a carrier ID everytime the ID is change and not the associate think in the same table (such as weight, material etc). The normal logging is based on the change of all logged item and not a singular item. Thanks alot.

Hi!I have upgraded from kepserverEX v5 to v6 on a new server, and tranfered the license:)My problem is that after a while all tags stops working and i see tag quality turns bad(Configuration error). It shouldnt be licens cause i see status on license utility=good. I then need to restart kepserver and it works again, so it kinda looks like license issue but idk how  😐 Anybody knows how to deal with this issue?

At the moment I have a small problem when getting the data from MQTT.I understood that Kepware can get the message from MQTT based on the JSON format, but when that format is not in the JSON, what should I do? For example, If my MQTT has a topic is "homeassistant/binary_sensor/IPC1" and the message of the topic is a string like 99-99-99-99 (not in the JSON format), how can I get the string 99-99-99-99 in Kepware? Any ideas?here is the picture for more understanding of my situation 

I am prompted to enter in my Windows admin login, which I have done, but nothing works. I've re-installed the software several times but no means to turn it off, Any way to bypass?  All I want to do is download my license.  

Hello everyone. We use KepserverEx as OPC UA server and MCE get tags from KerserverEx. Looks like there are some limitation in Kepserver side, MCE can't get more than 1K tags at the same  time, if exceed the limitation, the tags will be null.We tried to separate tags into several devices in Kepserver but didn't works. 

Hi everyoneBasically I'm trying to log data into an SQL server, I get the correct tag value and tag name, but with the time I'm not able to see it correctly in SQL In SQL I have the column Time as data type: timestampand the data that logs is in hexadecimal, so is not what I wantI've actually use data type datetime2 as well in sql but then I get an error in Kepware (Error Data Logger Plug-in Unable to query recordset on Log Group 'loggroup'. Reason: Conversion failed when converting date and/or time from character string)You can see it in the snapshots    does anyone know how can I actually submit the time in the SQL server? or like what datatype should be in Kepware and SQL? please help 

I just installed V7 Data Logger and would like to be able to import 4,000+ log items.  The connectivity suite has export/import capabilities. I don't see it for Data Logger.  Is there a way to manipulate the log items via JSON, REST api, or other method?

Hi, I am adding a new Mitsubishi Ethernet iQ-R series PLC to an existing FTView SE SCADA which is using Kepware for comms.  The issue is the addresses I need to add to the new Kepware config have not been mapped into contiguous blocks and are widely spread about.  Will this be a problem if I create static tags in Kepware with such scattered addresses ? When I began working on SCADA systems in the 90's I was always told that any data that was to be read or written to by SCADA should be mapped into contiguous blocks, otherwise you would end up getting multiple read transactions which would affect comms performance.  Is this still valid today with fast Ethernet and multi core CPU's ?

Hello everyone, I am trying to read data from Allen Bradley PLC. However, Kepserver is unable to read all the data. Below are few errors that are occurring: Date Time Level Source Event12/23/2025 6:20:52 PM Warning Allen-Bradley ControlLogix Ethernet  | Unable to read tag. Controller tag data type unknown.

Kepware version: Thingworx kepware Server v6.16.217.0We are having Fanuc Series 31i  Model CNC machines.We have Fanuc driver specific libraries for communication.Issue: We would like to communicate with 31i model but the driver is not listing the 31i model.Any work around or I am missing something?

Hi every one!I’m experiencing an issue with Advanced Tags in our Kepware project and need guidance.Setup:Kepware version: [KepserverEx 6]Channels: K1,Devices: PLC1,Source tags: Boolean / WORD tags under devices (quality = GOOD in OPC Quick Client)Advanced Tags: created in the global “Advanced Tags” folderAliases: created pointing to Advanced Tags and mapped to the corresponding deviceProblem:All Advanced Tags show BAD quality in OPC Quick Client.Source tags themselves read correctly and have GOOD quality.Even a simple Advanced Tag referencing a single Boolean tag shows BAD quality.The “Mapped To” option is only available in the Alias — the Advanced Tag itself has no “Mapped To” field.We want to confirm:If this is the correct setup for reading Advanced Tags via OPC/AVEVA.Whether there are any licensing, runtime, or configuration steps we may be missing that prevent Advanced Tags from evaluating.Thank you for your guidance.

Hi all,Just can't get my head around one thing!I am using Kepware to log a group of tags -more than 1000 tags-  apparently, Kepware’s DataLogger logs the entire group when any tag in that group changes. However, what I need is logging only those tags that have been changed not the entire group! I've done some research and ended up with enabling OPC UA in my project and using a Python code to log only the tags are changed! I was wondering if there is any other way except changing configuration of the project which I prefer to put it in bottom of my list!Any help much appreciated!  

Hello, I need to upload activation request file to repair my broken license.But i can't login to my kepware account in myKepware.It just keeps loading and loading..."we have made changes to My kepware. Please log in again"

Python which got installed during API installation is 3.10 and having vulnerabilities.We need to upgrade Python, will it support? if not then can we just upgrade API.Whole Kepware Application version upgrade supposed to be last option for us.

Hello community,I would like to know if it's possible to create a nested condition formula using a Derived Tag in Advanced Tags in KEPServerEX. Something "Condition ? Value_if_True : Value_if_False"The idea is to retrieve certain tag based on a tag value, for example:plc1secuence == 1 ? plc2tag1 : plc1secuence == 2 ? plc3tag1 : -1 Tried using IIF statement as well but it doesn't like it either... Looking forward to hear from you.Cheers,

Hello, I've been facing an issue for quite a long time. I have a GE VersaMax CPUE05 PLC connected to my PC by Ethernet. I configured it in KEPServerEX 6, the driver I used is GE Ethernet and it works great just like that. But the problem comes when i connect to the server in factory i/o.There is a big latency of about 2/3 seconds when it comes to tags update. I read the threads here about latency but none of them helped me. Scan mode and maximum bytes per request don't change the delay, it is still there. I have about 160 variables most of them which are boolean. The only thing i noticed is low amount of good reads (at least i think so) compared to writes. You can see the good reads after the first 10 seconds of simulation on the screen.The problem I also noticed is even if there were 3 variables in the project there was still a tiny lag when it comes to the variable update. Could this be the VersaMax Ethernet port? It is only 10Mb/s.  

Hello Kepware CommunityI am currently tinkering with the KepServerEX capabilities and have come across some unusual behavior. My task is to connect the Kepware to an MQTT server, retrieve the payload, and parse it into SQL. Everything goes smoothly if I use Kepware's default logging, which has 4 fields: numeric_id, quality, time_stamp, and value.It is ok when use a Narrow table format setting, which I set it as follows.And it return this sql tableNow I have a custom table that need to be fillAnd my column(s) set up, they have the same column registerThe logger is up and running, no error log but it does not log anything to the table.Which setting that I need to change ? Many thanks in advance. Have a great day.Best regardsTran Duc Thinh  

I have set up a simulator tag that receives its value from the link advance tag. The input of the link advance tag is the value from the ADAM READ-only Register address, and the output of the link advance tag is the simulator tag value. I have configured the link tag as the on interval mode, so that after every 100ms, link tag writes whatever the value is at the register address to the simulator tag. but the question is, even if the value is same after 100ms, is the update counter on the OPC client side should update its value or not ..?

I have a Prosoft PLX51-DF1-ENI card connected to a PLC5 via  a DF1 serial cable. I need to get a Factorytalk SCADA and Kepware to communicate to the PLC. Kepware is required to allow comms to an old historian. When Kepware is disabled the Factroytalk SCADA can communicate to the PLC OK. But once Kepware is enabled the Factorytalk comms start to fail.. In Kepware I am using the Allen Bradley Ethernet Driver and the tags show good values. I have the tag scan rates set to 1000ms. It seems like to Kepware connection is overloading the DF1 comms. Is there anything I can try to get this to work
