I have both Lookout 5.0 and 5.1 on my machine. In Lookout 5.0, the AB SLC500 driver had an ethernet option, there were problems encountered when talking to a PLC network and therefore this option no longer exists in Lookout 5.1. Well, the driver worked fine for me since I was only talking to a single PLC so I used it. Since then, I have installed 5.1. Now I have a similar project and want to use 5.0 and the AB SLC500 driver so I can use ethernet, however, this driver no longer works on my machine. Did installing 5.1 on my machine overwrite something associated with 5.0 that no longer allows this to work? I have also tried the AB PLC5 driver both in 5.0 and 5.1 with the same results. The alarm window shows "STS error 10, illegal command
or format"
