Kepware

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

hi, am trying to connect to my webserver using IIOT Gateway pulgins Configured as REST SERVER,Since it was tested using HTTP during testing , it was working fine , While for Production we have to do it in HTTPS.I Am a not able configure it , Support needed.Thingworx Kepware SERVER EX V6.16.217.0As iam trying to upload SSL certificate, its showing format error.''Failed to import the Certificate. the format is in valid''

I'm using Ignition to read about 4800 values from some BACnet devices. The on site enteliWEB app shows values updating every few seconds. But it can take a minute or more before Ignition updates the value to something else. They almost never match as it takes too long to get the updated value from KEPServerEX. The default poll rate in Ignition is 250ms and in KEPServerEX the BACnet device is set to "Respect Client Specified Scan Rate" by default. I've also tried the "Request Data at Scan Rate" set to 100ms. The tags always seem to show their scan rate at 100ms. 

Hi All - We are currently on Kepware version 6.7.1054.0Can you advise of which version of the application we can upgrade to, which is stable ? Appreciate the inputs!  Thanks, Danaraj AG

Hello people, I am having a configuration as TIA portal - Kepware - Ignition 8.1 Perspective. All my tags are healthy, communication is established and data is reading as well as writing. I am facing an delay issue in this configuration, like when I write on any tag in Ignition or from Ignition to TIA through Kepware, it is taking much longer time to update that tag, almost 20 - 30 secs. If I read/write values on memory tags in Ignition or Simulate PLC in TIA portal, it is acting very normal, the response time is fast within the respective software. All my settings are as per required settings, scan time of Kepware is in msec. I am unable to figure out what is the issue with this.I am using License versions of every software. Please guide through this.

HI, we are connecting multiple Fanuc controllers (15i,16i etc.) to Kepware (V6) through Fanuc Focas ethernet driver. Currently getting 3 fault tags as Battery Low, Fan Alarm and Emergency. Are there other fault tags present for Fanuc controllers and how can we access them to Kepware server.Please guide. TIA.

I am reaching out to address an ongoing issue I have encountered with OPC UA tags in my system. Despite correct configuration on the client side and the camera software visibly indicating alarms, these are not reflected in the client’s system, suggesting a possible interruption in data transmission between our camera software (OPC DA standard), KepwareEX 6.16 (OPC UA standard), and the client’s software.Problem Description: OPC DA Client Reconnecting: The server on the 'Camera' channel is attempting to reconnect due to a GetStatus failure, this error is displayed in kepware. I also see this error: access to object denied. | User = 'Data Client' , Object = ' Camera.Aira' , Permission = Dynamic Adressing. I have enabled the IP address firewall to allow the OPC UA IP address, maybe not correct. I also made adjustments to alarm settings in the camera software's web application have not resolved the issue.Softing OPC Toolbox Diagnostic: Tags within the OPC server group display as half

Hi, Somehow, In my OPC UA server, all tags got 15 subtags. These subtags are not visible in Kep Quick Client or in the Kepserver Configuration Window but visible in UaExpert or other OPC UA Clients. I want to stop it. Please guide me how to deactivate this!Thanks in advance. 

We know about Mitsubishi-Etectric series in Q series.Check the understanding of best practices in tags per channel on IoT gateways.What is the maximum number of tags on IoT gateways? 

I add a area and source to validate Alarm and Event funciton with UAExpertA/E should be activated as wellBut in UAExpert, I can't see it and I can't find any access to see it, please give me a help here, thanks  

Hello, I need to get some PLC Events data from an External OPC UA Server. If I am using UA Expert, we use the Event View to get the events, it shows general machine status which we need. Does KepServer have similar feature to read events from external OPC?

Hi  I'm using Kepware KEPServer EX 6.16 and connect a Modbus TCP device. Data acquisition is ok and Datalogger in ODBC also is ok.   The process is to acquire 3000 registers and archive in a Database. I noted that when Inter-Request Delay when is set to 0 the requests to the Modbus TCP device are very very high (higher then I need) but if I set to a number near the Scan Rate (5000 ms) of each tag I don't have all the value expected in database Static Interval (10 seconds),   how can I set this parameter (or other) to have less query and stay to the Static Interval lapse? I don't have issue about timeout or delay in communications. Albe   Best Regards   

Hi Community, I'm working in evaluation where Kepware Datalogger send data to ODBC Postgresql driver a lot of data and after 1.5 milions of rows the data inserting stopped until I delete old values from destination table in Postgresql+Timescaledb. Does exist any limitation in trail license (moreover the expiring indicated in Events) ? I'm using Kepware KEPServer EX 6.16 Best RegardsAlberto

KepWare.KepServerEx.V6 The client connection has reach a limit. Then I increased the maximum to 2,000. The number of clients shown at bottom right conner is still increasing to reach a limit again while we don't have a number of clients about tens. How to disconnect inactive client automatically?

I see that AB has Ethernet IP based IO called the 1732 family.They are industrial, hardened IO that seem perfect for the shop floor.dsI'd like to be able to connect these directly to the Kepware Server.IS THERE A KEPWARE DRIVER THAT CAN TALK DIRECTLY TO AB ETHERNET/IP BASED IO?Thanks.

I was working with Kepware on a problem and during the discussion we enable a trial of IoT Gateway. I wont be using it in my application. But now it is filling my event log with "Time limited usage period on feature IoT Gateway has expired." Also, while on a trial of KepServer and this IoT Gateway, a notification shows up every 30 seconds to tell you it is a trial with limited time. It was so distracting I just uninstalled the software and work remotely with the actual licensed software. Now I just need to get rid of the IoT on that. Thanks, Scott

When I click on "Launch Quick Client Here" the quick client opens showing 640 tags. Most of which are unwanted. I have the timestamp for the opening time, quality Good and Update Count 1. All but two of the update count values remain at 1 and the time stamps for those value remain at the starting time. Two tags are updating every couple of seconds. Of the rest of the tags 7 are marked Bad. In the KepserverEx event log there are 12 tags marked "Unable to read tag" with a CIP Error = 0x5. Am I really getting data from the PLC? How can I tell if this is accurate? How do I make the other tags update like the two anomalies? KepserverEx 6.14.263.0Thanks for the help.

I have temperatures 10 times higher than they should be. I read the article "How to scale data from a PLC in PTC Kepware Products" (https://www.ptc.com/en/support/article/CS291338). It resulted in a tag that errored out with a CIP error 0X5.I created the new tag, gave it a name and description and the address. and set the Scaling to linear, 0 to 10000. And got the error. I tried changing the data type from Word to Float and Short, but they threw the error for illegal data type.  Any other suggestions? Scott  

Dear all,as explained in the Subject there is a problem with the Runtime automatically booting up in Kepserver 6.16.This article applies to 6.15; this solution doesn't work for 6.16.Article - CS412894 - Unable to boot KEPSeverEX 'Runtime service' without manual intervention (ptc.com)Does anybody know to fix this?Kind regards and thanks in advance 

Hi Everyone,I am very new to OPC UA Security Policies, currently using KEPServerEX and would like to know if it supports integration with an OPC UA Global Discovery Server (GDS) for managing certificates. Specifically, I have the following questions:Does KEPServerEX support GDS? If yes, how can I set it up to work with a GDS to manage OPC UA certificates?Certificate Management for Multiple Clients: I have hundreds of OPC UA clients connected to my server. What is the best way to manage certificates for these clients?Handling Certificate Expiry: If multiple client certificates expire simultaneously, how can I manage this scenario effectively? Is there a way to automate the renewal and distribution of these certificates through GDS or any other method?Any guidance, best practices, or step-by-step instructions would be greatly appreciated!Thank you in advance for your help!
