Kepware

Hello,I'm looking for a solution to retrieve data from an Omron NJ101-9000 controller and insert it into a MySQL server. I decided to test Kepware (KEPServerEX) to see if it can be used for this project.So far, things are looking good — I downloaded the trial version of Kepserver, successfully scanned the controller's tags, and connected to the MySQL database via ODBC. Everything seems to be working, but I've encountered one issue.The problem is that the data is being written to the database as shown in the 1 figure, even though I'm using the "Always Triggered" mode with a 5000 ms interval.What I want is for the data to be written to the database like it's shown in the 2 figure. 1 Figure.2 figure The second option is the most suitable for me because the data will be read by Grafana.So, could you please advise me on how to write data to the database in the way shown in the second example?If I manage to get this working, I would be able to submit a request to the purchasing dep

Hello community,  I'm using kepware with Datalogger connecting to a SQL Server.When Kepware runs the data logger, the following error occurs. Log group  ~ Unalbe to connect to data source 'Kepware_DB_TEST'. Reason : SQL server does not exist or access denied. Connection Open(Connect()). Kepware and the database are on the same IP subnet, and SQL Server Express is being used. I requested the company to open SQL port 1433, but they said it's meaningless because they are on the same subnet with only the last octet different. I'm not sure what I should be checking. When I performed a telnet test from the Kepware server to the database server on port 1433, I received the error message: 'Could not open connection to the host, on port 1433: Connect failed.' Any suggestions or things I should check would be greatly appreciated. 

Hello,   I'm calling, from my computer, the Configuration API of a remote KEPServerEx instance (version 6.16, running in a host). My .opf file is stored in the local computer.   I wonder if there is a way to use load this file in the KEPServer instance. I feel like the file needs to be stored locally on the server when using the /config/v1/project/services/ProjectLoad endpoint.   Thank you

Hello,I am currently in the process of converting SNMP data to Modbus TCP for a power monitoring server using Kepware. Since there are over 300 devices, each with 14 registers, I wanted to distribute the output across 3 different IP addresses.For example: 192.168.22.124, 192.168.22.125, 192.168.22.126Initially, I assigned all addresses to a single virtual network card. Since I encountered issues with this setup, I created additional virtual network cards to assign each address to a separate network adapter. Unfortunately, this did not change the following behavior.The Kepware server and the monitoring client are running on the same virtual machine. The translation from SNMP to Modbus TCP works so far, but I have the problem that the values of the same IDs from different IPs overwrite each other.In Kepware, I can see that, for example, 192.168.22.124/502/45 sometimes takes values from 192.168.22.125/502/45 or 192.168.22.126/502/45.I can see values on 192.168.22.126/502/130, although onl

As per the original post.    Wonderware, InTouch, AVEVA (all the same thing) have a do not have a good OPC implementation (UA or DA).  Only the loopback IP address (127.0.0.0) can be used by AVEVA to address the server.  Thus, ANY server software must be on the same machine as AVEVA.  This is not the way OPC was meant to work.  I have been experimenting with have a copy of Kepserver on the server hardware (Kepserver/server) and additional copies on each workstation (Kepserver/AVEVA/worikstation).  The objective is to use the Kepserver/server to communicate with multiple PLCs to collect data via Modbus and then share the data with Kepserver/AVEVA/workstations.  This is a lousy way to implement OPC, but I haven't found an HMI that works any better.  Does anyone have any suggestions for an alternate HMI?

Hello allI am working on a project that involves integration of thingworx for real time performance monitoring. This involves investing in new machines with PLCs that ease connectivity with kepware. However, another case involves legacy machines with no PLCs. Data is collected and logged in manually into SQL-based excel platform.We aim to eliminate the use of excel for visualisation and use just thingworx as a single analytics monitoring platform. How can we move data from legacy  SQL server to kepware by using data lake functionalities or power BI? Please if an architecture is possible, it will be more helpful.

Hello, i have a problem with connecting to a S5-PLC from Siemens. I want to use WinCC V8.1 to connect with a OPC server in this case KepwareEX. Now i want to know if it is even possible that the OPC server can connect with PROFIBUS FMS wich the S5-PLC uses. Kind regards Wesley

Hi,I'm writing to this support to understand if and how could be possible to reduce the usage of CPU when a big configuration of Kepware is running.The configuration it is composed by almost 80 device configured to query each 10 seconds 2000 Modbus registers for each device, values are archived in a Microsoft SQL Server through Data Logger triggered each 10 seconds.Actually only 2 devices ramps the CPU usage to 10-12% for the server_runtime.exe almost and I don't know what happen when I enable all the 80 devices, how can I reduce to the max the usage of CPU.Which are the information that you need to support me in this issue?Let me know and I can provide the screenshots or logs or config... KEPServer EX V6.11.718.0Modbus TCP/IP Ethernet V6.11.718.0Data Logger PlugIn V6.11.718.0 Best RegardsAlb

Hi, I'm using an Advanced Tag of type Derived to perform an AND between two boolean tags. It is expected that if one of them is Unknown because the PLC is disconnected, the result will be 0. If I use only the Derived Tag, the result is shown as Unknown in Quick Client. If I use a Link Tag to copy the result of the Derived to another boolean tag, it shows me the value 0 which is the expected value. Is there any way to get the value 0 without using a link tag?

I'm opening a Project from the backup folder while offline.   The Project opens and is exactly what I want to run in KepserverEX6.  I go to Runtime and select Connect, and it reverts back to the original Project.  What am I missing? I've seen something about Runtime uses the default.opf file to run.  I don't see a default file.  The original file that it keeps going back to is Simulation Driver Demo.

Unable to get KepServerEX connected to my Mitsubishi FX3U processor using a FX-ENET-ADP. Have tried UDP and TCP with no success. Currently plc setup is UDP,1025,192.168.1.250,1025. KepserverEX is set to Mitsubishi Ethernet, and UDP, 5000,0 (have tried other combinations) at this time only attempting to read one tag D250 Have also swapped over to TCP with no success. Any help appreciated Thanks, Bob

I have an OPC-DA server on which i need to expose a number of tags to a remote network.I want to use KepWare to transition from OPC-DA to OPC-UA. How is this done, and using which license / suite?This should also support writing data from OPC-UA back to OPC-DA server. In other words:- source: OPC-DA server- Kepware: connect to source using OPC-DA client- Kepware: provide an OPC-UA Server- target: clients can connect to the OPC-UA server and read/write tags from/to the OPC-DA server through Kepware   

Hello everyone, I'm new to Kepware and I'm trying to connect around 50 channels, each with one device, all using the Allen-Bradley ControlLogix driver. Each device has around 300,000 tags. When I try to start the Runtime, the application seemingly times out and fails to initialize. Is there any way to optimize the application so that it can start under these conditions?  ThanksGuilherme

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
