I am looking for a tag in KepServerEX 6 to get the current system date and time, these tags could be used for further usages such as PLC date time updates.

The time must be separated into simple HH and MM tags.

I have searched in the simulator and advanced simulator tags but nothing found.

Any help appreciated

  • The client would not have built-in tags. I don't think the KEPServer simulator does either. Are you looking for any OPC UA server that provides this or do you need to have it in KEPServerEX simulator? – eglease Feb 16 '23 at 15:18
  • @eglease I have the same idea about KEPServerEX. I need an OPC UA server that can do the following jobs: 1. Read/Write PLC tags with proper divers for various PLC manufacturers 2. Able to connect to .Net apps(with OPC.net nuget package) 3. Log Tags to SQL database based on conditions 4. Adjust date time in PLC. 5. Log alarm and events in a database. No matter about the KEPServerEX or any other ones. – milad Feb 17 '23 at 08:25

    For your situation, 1. Kepware, Softing, Matrikon, maybe a few other have various PLC drivers for different protocols. 2. Are you looking to develop something yourself or can you buy a turn-key SCADA system? 3. There are a number of products that connect directly to SQL including Softing, Matrikon, and Integration Objects. 4. This would depend on the properties of the PLC. Some have their own built-in OPC server, others may not have a time tag to adjust. 5. See 3. – eglease Feb 17 '23 at 19:01
  • Also look at SoftwareToolbox TopServer. – eglease Feb 17 '23 at 19:20
  • to get more info, in 1. I have used kepware and it's OK 2. I have developed 2 apps, one is a .net razor app and the other a UWP app. both of them connect to KepServerEX and manage tags(read/write) with OPCFoundation.NetStandard.Opc.UA.Client package from nuget. 3. There is a data logger plug-in in kepServerEx also which logs tag values to SQL DB and it's not bad(only some special triggers are not possible) 4. I think for this one may be a good idea to program a C# function in my apps to get straight to what I need to be change in PLC. – milad Feb 19 '23 at 07:33
  • 5. KepServerEx has an AE plugin but AE is not possible to log in DB in data logger in Kepware also I didn't find a way to connect it to my UWP/razor apps . Do you have any recommendations about how to connect opc alarm and events to C#? – milad Feb 19 '23 at 07:37

    AE and HD are built-into OPC UA but I never used them. You can try a commercial SDK like Unified Automation. I know it supports both data formats. – eglease Feb 20 '23 at 14:32

For that you could mount a local mqtt broker that retrieves the srtructre of mqtt like:

Links example:
>http://localhost/webservices/home/GETSERVERTIME+Hour
> http://localhost/webservices/home/GETSERVERTIME+Minutes
> http://localhost/webservices/home/GETSERVERTIME+Seconds

mount a mqtt client on your kepserverex Response Should look like this Maybe Using c# could be more easy to you: C# .net guide

Also you can mount a Modbus master on your windows and retrive the info you need with modbus tcp/ip client, i think this is easiest way: Mosbus master and slave c# .net
