When you send an Enter Download/Upload mode command, the

Industrial Terminal port is disabled until you send an Exit

Download/Upload mode command. When the Industrial Terminal port is

disabled, it enters the Mode Select State. In order to leave this state, you

will have to manually select a mode at the Industrial Terminal.

Exit Download/Upload Mode

This command takes the PLC-2 processor out of the Upload or Download

mode. Use this command to restart the PLC-2 processor after performing

an upload or download operation.

If you don’t send this command after a Download/Upload mode

command, you will have to recycle power at the 1771-KA or 1771-KA2

module to enable Industrial Terminal communication.
