You cannot rename an I/O channel from the I/O palette. Only I/O blocks that you have added to your Processing Map are available for channel renaming. This procedure assumes you have already added one or more I/O blocks to your Processing Map.
note: The process for renaming a channel is the same as for renaming a block.
note: When entering names and other text, such as labels and notes, you can use nearly any Latin character and many symbols. For more details, see Allowed Display Characters.
