Hi osmanmom, thanks for that, but have that info and driver pack, and still no go. From what l understand the KE500 driver in Citect is the half duplex driver and should talk directly to the PLC CH0. I have had PLC working on half duplex with RSlinx but when l remove the linx driver (delete it from linx) l cant get comms citect direct to CPU CH0.
If someone can come up with a solution l would appreciate it, but l will go back to talking via full duplex ( as this has nearly broken my brain having to default the CPU to get back to talking)and l can operate citect. So now it is only a wish to see it talking direct. Thanks for you guys help. Time for another red.
Regards
