title: TwinCat issue : state change to op mode failed master state preop is insufficient
body: <p>I am using TwinCat to connect to my slaves , once I am running TwinCat in config mode all slaves go to op mode. When I switch running TwinCat to run mode : error box : state change to op mode failed master state preop is insufficient. I tried to run TwinCat in ‘’ run mode’’ in order to run the plc code.</p>
  
  <p>The plc code is running fine without any error . Do I need to link something? How can I resolve this problem thanks in advance</p>
