PLC simulation with OPC Server

[Nazato]

I'm a beginner in this area so maybe this is a really silly question. I've been trying to use the CODESYS V3.5 SP8 Patch 2 software to write a PLC program and use the Codesys OPC Server V3 to connect to AdvancedHMI. I'm using the Codesys Control Win Systray to simulate a PLC using my computer. Would the program work fine with only the simulation?

If it does work with a simulation, then I still having some other problems. The message I'm getting is: Failed OPC Subscription Start [OpcDaCom]

I believe I did manage to get the Server Name correct (CoDeSys.OPC.DA) as I'm not getting the Network Error message anymore. I'm just not sure about the variable name and where I have to input then in the PLC Properties panel. I'm using one basic button to activate a pilot light. For the button I put the variable name in the PLCAddressText and for the light in the PLCAdressValue. I've tried the PLC_NAME..IteMName  model for the variables name.

Also, for the OpcDaCom driver I'm not sure what to put in the OpcGroup and OpcTopic. I've attached a screenshot with the debug information if it is any useful.

Thank you in advance for the help

You should check the last post in this topic:

If Matrikon Explorer can communicate with your server then AHMI can do so as well.

Here is the BasicButton usage in short (for some of its properties):

PLCAddressClick: tell the button what address in PLC it should change after you click the button.

OutputType: set to what you need the button to do to the above address (either write True value or write False value or toggle between the two with each click of a button or write specific value from the ValueToWrite property or temporarily set True or False value while the button is pressed).

PLCAddressText: the PLC address set in here will replace the Text property with its value

PLCAddressHighlight: the PLC address set here will turn the Highlight ON (when True) or OFF (when False)

PLCAddressSelectTextAlternate: the PLC address set here will, when its value is True, override the button's Text property with the value specified in the TextAlternate property

PLCAddressVisible: the PLC address set here will, when its value is True, make the button visible and when its value is False it will make the button invisible

Thank you! Your replies helped me a lot. Using the MatrikonOPC Explorer I managed to get the variables name and make the HMI work.

That was really helpful, thanks again!

If anyone is trying the same and still having problems what I noticed is that you only need the OPCServer, in the OPCGroup and OPCTopic fields you have to leave it blank so that it works.
