Kepware

Hello Community, I am using KepserverEx 6.17 with Datalogger connecting to a SQL Server.I have a strange error that happens once or twice a week, where the datalogger cannot query the recordset due to the following error: Unable to query recordset on Log Group XXXX. Reason: TCP Provider: An existing connection was forcibly closed by the remote host. Communication link failure I already went through the knowledge base and apparently it is related to a lock on the table defined in the log group.After a couple of weeks deep diving in the SQL Server I cannot find any lock on the mentioned table during the time this errors happen. I simply cannot find a reason for this behaviour. Has anyone also faced this issue? What could be the problem originating it?Any suggestions would be appreciated. Thanks.

I am attempting to use KEPware's SNMP driver to read off of a network switch. However, while KEPware can see and identify the device as running SNMP v2c using Device Discovery, I cannot get any data in KEPware.Using net-snmp on the same server, I am able to read data off of the device (e.g. "snmpget -v 2c -c <COMMUNITY_NAME> <IP_ADDRESS> IF-MIB::ifOperStatus.1" gives "IF-MIB::ifOperStatus.1 = INTEGER: down(2)" in response, which is good data), so I know that the switch is configured for SNMP properly and the server can read it.None of my tags produce good data in the OPC Quick Client. Inside the SNMP channel I've created, in a standard device created through device discovery with the switch, neither an imported "IF-MIB" module nor a static tag pointed at "if-MIB::ifOperStatus.1" is able to read anything but "Bad" data in the quick client.My license is in good standing and is installed properly. Other (non-SNMP) channels within this KEPware are able to communicate with

Hello, I am installing KEPServerEX6-6.13.266.0 on my PC, but I keep getting an error message that shown as below, can someone please help me?  

Hello everyoneI am tring to read 29 elements table form the compact logix 5300 (revision 20.013).I created proper channel and the device, i am able to generate program and export the tags. i tried to make a test and read the element from the table trought the kepware, but when i did it the values are not proper but in specific way:When i read table[0] i see the values from table[1]when i read table[1] i see the values from table[2]when i read table[2] i see the values from table[3]etc..i am not able to read the value from table[0] because of the offset. has anyone occured with similar problem? Best regardsNatalia

To be clear, I must create a channel in Kepserverex which requires I select a PLC driver from the list, before I can find Device Discovery in the context menu (See page 85 in the KEPServerEX V6 manual)?  The Omron NJ channel I am using did not have "Device Discovery" in the context menu. But the manual does say "is available for drivers that support locating devices on the network." Of course, I don't know which drivers support it or not.I created an Allen Bradley Control Logix Ethernet channel, then right clicked on the channel to find "Device Discovery." But there was no Device Discovery option in the menu. Should "Device Discovery" be in the context menu always? Is there a setting I am missing? Is there a way to use Kepserverex to look for an OPC connection or tell if a PLC has OPC UA or OPC DA enabled?  

Hi All,I am trying to use DDE to get the data from Kepware to an Excel spread sheet. This was working for a day or two then quit. I have had help from a super nice couple of people at PTC. Alin in Romania and Brent in Maine. But we are not able to get the data and there is no apparent reason for it. The Excel file has formulas in the cell that look like this '=kepdde|_ddedata!OmronNJ.MespackHFFS.ReaTop2Temperature.' When first typed into a new spreadsheet, it was populated with the current temperature. For a while it even updated with each change of the temperature. As well as all the other tags written into the spreadsheet. Then I saved the spreadsheet. I opened it Monday and there was nothing but #REF in all the cells. Starting from a blank spreadsheet, I typed in the same formulas and got the current values. But they would not update. I could see the temperature changing in the Quick Client, but the spreadsheet was not changing. I opened a new spreadsheet and typed the formula

I wanted to know what the options for high availability are in KepserverEX for IOT Gateway MQTT Client so that the data is always available even if one of the kepserver is down.

 Redundancy master does not detect available OPC servers on the network(entire netwok), is it possible to add a server manually?All tested clients connected OK,  then maual add servers by name or IP. OPC servers - Windows 11 with Keepware 6.16OPC clients - Windows 2022 with Redundancy master2

In know that starting in Kepserver 6.11 there is a max of 4000 OPC Groups allowed. I would like to know were in Kepserver I can "see" the current value of the number of OPC Groups. So far the only thing I have seen is an event message once we have hit the current limit. So if I have it set to 100 and we have 100 groups, when the 101 group is attempted we get the error. BUT - It sure would be nice to know the CURRENT value of the number of groups so the user can appropriately set their own limit, as well as monitor this number to determine if there is a bad acting client. Where in Kepserver can I see the current number of OPC (DA) Groups.

I am creating devices with the same IP and Slave ID and distributing the tags among them. When I create a device in the Kepserver application and modify its properties, the changes seem to be applied after saving. However, when I reopen the device, I see that the changes were not actually applied. However, if I copy a device with the desired properties and adjust it according to the device I tried to modify, everything works fine without any issues. Additionally, some devices like inv_02 and inv_05 constantly fall into "bad" status, losing their connection. How can we resolve this situation?

1. What problem are you trying to solve?I have an application and i can send data using HTTP connector. How to add that HTTP connector in kepware?.

Hello Team,I searched on ChatGPT found this below Observation, I tried to find same file but could not able to get it. If any idea about it, please let me know. My main concern is client's Kepware 'server_runtime.exe' service consuming 1.84 GB memory with 99%CPU utilization. Kepware is having around 36000 Tags which are connected to the 2 OPC UA client. OS details:  Moreover, I referred the following document CS281787.

Is there a way to temporarily force a value in KEPServerEX for tags readding their value from a real field device? Seems the only way is to recreate all the tags in a new project in a sim driver.

Hello, I have some problem with use of driver for siemens PLC on KepServerEx v6.The server is unable to load the driver with this log message:"Unable to load driver DLL 'C:\Program Files (x86)\Kepware\KEPServerEX 6\drivers\siemens_s7_plus_ethernet.dll'."There is already a topic on the PTC support page but it's not enough precise for me (https://www.ptc.com/en/support/article/CS370652).I uninstalled then installed the driver but it's always NG. The dll file is of course in the good directory.Has anyone ever had the problem?  OS: windows 7 SP1KepServerEx: v6.13.250.0siemens_s7_plus_ethernet.dll: v6.13.250.0 Thanks

Kepware: Is there a way to disable the OPC UA client browsing option in Kepware or restrict the view to only configured channels or tags? Is it possible to disable the browsing feature in Kepware so that OPC UA Client users cannot navigate to other data?

Hi,  I am looking to transform data points from some of our older FANUC system R-30iA and R-J3iB welding robots, Arctool software version 6.22 to 7.70  we purchased the HMI Device SNPX option, (FOCAS is CNC only and not available for robots) which provides a simulated GE plc communication protocol. My goal is to provide OPC-UA tags to Machine Metrics monitoring platform         I am still using the trial version of KEPware Server EX. using the GE OPEN driver for connectivity.  Seems to be connected, but it does not appear to be pulling in the SNPX_ASG variables. My question is before I purchase the GE Suite license, is this the correct driver and software to use?      Here is a snip from the variables that I would like to read into KEPWare; ##.120.##.##/MD/SYSTEM.VA[*SYSTEM*]$SNPX_ASG Storage: CMOS Access: RW : ARRAY[80] OF SNPX_ASG_TField: $SNPX_ASG[1].$ADDRESS Access: RW: SHORT = 1Field: $SNPX_ASG[1].$SIZE Access: RW

I am having a Datalogger configured in Thingworx Kepware Server.Already, Log Items are configured there. Now, I would like to add New Log Item but both the options i.e 'New Log Item' and 'New Log Items' are showing disabled (unable to add).Checked License Utility. It is good.
