I have a problem when I use VBA to get a tag from the HMI or PLC, the VBA does not get the tag value right away always. For example to enter parameters we created a keypad popup, we want to display the current value associatd to the parameter when the keypad popup opens. It seems that we need to close the popup and open the popup again to have the value display. Sometimes we can get the value displayed on the first shot. Any ideas what can be wrong?
