5–4 CLI Commands
■ The controller processes each command in sequence. You can continue entering
subsequent commands while the controller is processing prior commands. A
controller experiencing heavy data I/O may respond slowly to CLI commands.
NOTE: Due to space limitations, some examples in this manual contain commands
that exceed one line in length. In these instances, the paragraph preceding the
example identifies which command is continued on the next line.
Specific keys or a combination of keys allow you to recall and edit the last four
commands. This feature can save time and help prevent mistakes when you need to
enter similar commands during the configuration process. Table 5–1 lists the keys
used to recall and edit commands.
Unit Naming
