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.
