Thanks for the reply rubha.
My update time is set low enought, the reason I need to read the actual I/O is that the PLCs are always online so I can't make anymore Interger/Floats or B files. No idea why who ever configured didn't make enough but I'm running out of internal I/O. any other...
I'm having troubles commuicating between SLC5/05 PLCs and Wonderware. Hard Inputs and Outputs have to turn on a Bit before Wonderware will see them. I have no problems seeing Intergers, Floats ect. Thanks for your help.
