I have some buttons on a screen which set certain PLC registers to a numerical value. Four buttons set one register, another 2 set a different registers and so on. Beside the buttons I have a text entery field which is sent a string based on the button pressed. Every thing appears to be working but yet the text box for one set of buttons is not changing. I find if I go away from the screen and come back the text has changed. As an experiment I placed a pop up screen to cover the text. When this is brought up and then closed the text has changed. Is there a problem with the way the screen is accepting the changing text but not refreshing until the screen is refreshed.

Another problem I have found with the text entery fields is that I had to turn on byte swap. Now when I use the web server to browse any of my settings screens the text is showing reversed. I assume because the byte swap does not work for the screen capture. Also I am finding that if I go to a screen on the panel it appears to be blank, but if I leave the screen then come back to it the text fields have the proper data.

1) For the text display updates, is this a dynamic text or a look up text? Is your panel a 12 " or 15 "? There are some screen update issues with the 12 and 15 inch that Koyo is working on. If you want to call tech support and send them your project, we can test it here and see if we can duplicate it.
2) The byte swap on the webserver sounds like a bug.
3) The blank screen also sounds like a problem with the webserver.

1, The text used is a Text Entry field with style 2 turned on so that the PLC is sending the ASCII string to the screen. I have fixed my problem by turning the screens into pop up windows.
2, This is the type of screen Iam using, EA7-T8C (640x480)
