[@TohidAlizadeh]

Thanks for the video. You explained it in a very nice and clear way.

[@CarlosAbner]

Thank you for the video, there is a lot of good information. Maybe you said but I don´t remeber, which Codesys version are you using? I am using 3.5.16 and I don´t see object "Communication Manager", I see that is like a cloud the icon but I dónt have it, it comes in latest version or I could install a package?

[@Codesys-AutomationSoftware]

The Communication Manager is available as of CODESYS V3.5 SP17. Thus, try it with the latest version :-).

[@kaizokudc]

Hello Sir, I am trying to configure my codesys softplc as an opc ua client and read data from a different opc ua server. When I add data sources manager to my project, opc ua server does not appear among the options. I only see codesys applicationv3. Is there any other way? Another question I have is, is CODESYS OPC UA CLIENT SL license required for this situation? BR,

[@Codesys-AutomationSoftware]

Did you install the CODESYS Communication Add-on with the CODESYS Installer? That is needed to setup a OPC UA Server in the Data Sources Manager. You don't need a license for that. The feature has a demo mode.

[@vaughandocker6292]

thanks for the video, how do i determine the url of my opc server? as you had yours already prepared. thankyou

[@Codesys-AutomationSoftware]

The URL of your OPC server is generated out of the IP address of your PLC. For example, an IP address of 192.168.0.1 results in a URL of: opc.tcp://192.168.0.1:4840 There are several different ways to get the IP address of your device. You could either see it in the device log in the CODESYS Development System or use tools like Advanced IP Scanner to search for it, just to name two options.

Thanks for the video. I have a problem I can't select the data source type as OPC UA server I only have CODESYS ApplicationV3, do you have any advice? thank you!

[@Codesys-AutomationSoftware]

Since CODESYS 3.5 SP17 the data source "OPC UA Server" is available within the Data Sources Manager besides the CODESYS Application V3. On reason might be that you are using a version < 3.5 SP17.

[@user-mi3xd7jh3u]

Hello! How many clients can connect to a single port 4840 on server simultaneously? For example, i wanna take data from a single plc via opc ua to: Weintek panel 1, weintek panel 2 and SCADA ( tia portal for example). Thanks

[@Codesys-AutomationSoftware]

@user-mi3xd7jh3u There is no general answer to this question. How many clients can connect depends on various factors, e.g. the performance of your hardware and how much data the clients retrieve. Since three clients is not a lot, there is a good chance that this will work. 😉

[@pedromendes148]

I don't have the Symbol Configuration Object when I click on "Add new object" I am using the latest version of Codesys. Am I missing something?

[@Codesys-AutomationSoftware]

Please check in the CODESYS Installer whether the Addon package "CODESYS Communication" is installed. Probably this is missing.

[@user-lt2nz6hh7k]

Is there a way to edit the publish interval of the exposed variables? And which is the default one? I am using UaExpert as opcua client and I can't manage to read the values faster than 100ms

[@Codesys-AutomationSoftware]

Currently the fastest default sampling rate is 100ms. But the value can be set via CODESYSControl.cfg. On good hardware you should be able to reach faster sampling rates, maybe even as low as 10ms. We didn't test this yet however, since there were no complaints that the 100ms sampling rate is too slow.

[@user-lt2nz6hh7k]

@@Codesys-AutomationSoftware Thanks, which is the variable to change this sampling rate? Or can you redirect me to a related documentation? The ones I found did not cover any information about the opcua settings. Thanks

[@Codesys-AutomationSoftware]

The sampling rate needs to be changed with an additional setting in the config file. In order to do this, you need to open the CODESYSControl.cfg file and search for the [CmpOPCUAServer] section and add "ItemMinSamplingRate". The value of this setting is in ms, so 50 equals 50ms. Feel free to write us an email in case this doesn't work for you: [e-mail]

[@JoshuaChristianJavier]

May I know what OPC Server should I use to integrate Codesys to Factory IO?

[@Codesys-AutomationSoftware]

Simply use the CODESYS OPC UA server which is part of the SoftPLCs in the CODESYS Store, e.g. for PC based systems (CODESYS Control Win SL or CODESYS Control RTE SL under Windows or CODESYS Control for Linux SL) or for other systems like the Raspberry Pi (CODESYS Control for Raspberry Pi SL MC).

[@veoteveo1]

can it be used with wonderware intouch?

[@Codesys-AutomationSoftware]

CODESYS supports all OPC UA Clients, so the usage with Wonderware Intouch should be no problem.

[@veoteveo1]

@@Codesys-AutomationSoftware thank you! Is there a way to migrate a AB plc program to codesys?

[@Codesys-AutomationSoftware]

You can migrate your program to CODESYS if the IDE you use to configure your PLC offers an export function which is PLCopenXML compatible. So you just need to export the PLCopenXML file and then import it into CODESYS.

[@veoteveo1]

@@Codesys-AutomationSoftware i will try, thank you

[@veoteveo1]

@@Codesys-AutomationSoftware Dear Sir, Thank you for the kind help. I am unable to connect codesys to intouch SMS opc server and then to my intouch HMI. it seems as if the data is not communicating from the codesys to my SMC Archestra. I set up the symbol configuration, selected the variables and then build, download and run. I may be missing something in codesys? I have been on the phone with AVEA wonderware for several days and we cannot get the comms working. Have you tested it with intouch archestra SMC? thanks im kinda lost now...everyone that posts a video uses kepserver to comm with intouch, i haven seen anyone use archestra smc intouch.
