    I have an issue where I have extended a function block from a library, but when I try to use it with the library defined interfaces I get the attached error. Error Text [ERROR] PRS Alternator Test: gAlarmManager(Line 5): C0032: Cannot convert type 'PceAlarms.IAlarmManager(pcealarms, (powercore engineering))' to type 'IAlarmManager' Base FB Declaration in Library FUNCTION_BLOCK AlarmElement IMPLEMENTS IAlarmElement, PCI2.IBasicLogger ...

    For those who suggest using hardwired buttons, it is not possible in my application. There are many "manual" buttons and our HMI should be mobile. You have to Walk around the site in order to operate different sections. It is not possible to put multiple panels around, because then we will need tens of them... One of the reasons we have chosen Codesys for our application is the versatility and high end technology it introduce. I think that asking a button to stop operating in case of connection loss...

    in this post you can find a project to login from IEC code. After creating two user groups in the usermanagement, maybe this is a other simple way to allow or disable user inputs on specific clients and visu objects. I can't use the currentvisuvariable in my project, so I login or out the right user during the iteration for synchronisation or check if the right user is logged in, as Chris.O described.

    Tested not what I want.. I want something regardless where the program has changed the method FB_Exit seems to work as intended but only if I have changed in that particular FB.

    You can Count it on your own. Within this post I shared my Program (not the Code-Sniped, but the Project to download) Here I Iterate all clients and read out some information. You can also geht som Usier-Info (Current logged In user for the different Clients) So try e.g. If Current logged in user <> '' Then count+1 Or you use the code-sniped and use "pClient^.GlobalData.CurrentUserName" Inside the Iteration e.g. code If...
