Here's the Quick Start Manual for ControlFlash...
ControlFlash Quick Start Manual - Publication 1756-UM105
Go here to get the latest firmware for your adapter...
http://compatibility.rockwellautoma...oad.aspx?famID=4&Keyword=Controller&crumb=112
Type in 1734-AENT in the "Product Search" field.
If you have a Series A then the latest available is revision 3.012.
If you have a Series B then the latest available is revision 5.012.
If you don't have the latest Add On Profile for these adapters then it's available for selection with the firmware download.
Install ControlFlash from the downloaded zip file.
The adapter must be inactive when you flash it. i.e. not connected to a running a controller. I do not recommend using anything between your computer and the adapter. Remove the adapter from the network and use a crossover Ethernet cable to your computer.
If you have any questions about ControlFlash before proceeding then let us know.
Once it's flashed, you'll need to set your IP address...
