Function execution on primary server initiated on client

Function execution on primary server initiated on client

Dear,

I noticed that after reloading project on server, I can't execute function on client PC (Project is in Zenon Supervisor Version 8.00 SP0 Build53129, client is in Operator 8.00),
but when I execute function first time on primary server after that I can execute function from client PC, without problems.
Function execution is set to Execution on primary server, and function is need to execute just there. Its normal function on button that calls vba script.
Do you have some idea why I can't execute function first time on client?

BR,
Albert
