Hi, In my HMI project I use a subroutine triggered by a button. All it does is check if certain variables are triggered and if the condition is met I use the showpage function to call a popup page. Because of the update interval between PLC and HMI to 100msec the condition inside the subroutine is not always met although the PLC has completed the job behind the scene. Is there a way to implement a "wait until strategy" instead of the straight "IF...END_IF" I am using now ?
