UPDATE: As of November 2017 this procedure still works as long as you follow all the steps, including Step 5. Hi Shawn, Thank you for the useful information, I was able to download and install the software. I do have a question regarding communication with MicroLogix 1100 controller. If the CH0 is configured for Modubus(RS-485 network) how can you have access to the controller to download the program and monitor online other than disconnecting it from the network and connect to personal computer.
Can you use CH1 to connect your personal computer to controller to download the program and monitor online? Thank you, Calin.
