SLC5/05 comms with Wonderware
(OP)
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.

RE: SLC5/05 comms with Wonderware
You can move your discrete data to an integer register to minimize communications. Wonderware reads blocks of data (1024 words)wether data is there or not. So, if you are using N7:0 and N10:5, then 2 different read blocks are performed.
Try combining them into one data table for discrete and integer data, and one for Floating Point.
Hope this helps.
RE: SLC5/05 comms with Wonderware
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 helpful ideas? TIA

configure the tag as: Slot1 = I:0.1 etc.
