Access Levels for the Command Line Interface
The Command Line Interface provides two access levels of commands:
Monitor access level commands – these are commands that do not affect the operation of the
module, or that are read-only. Monitor level commands are always accessible. The Command
Line Interface always starts (or restarts after inactivity) at Monitor access level. See chapter 2 for
detailed definitions of Monitor level commands.
Modify access level commands – these commands can be used to change some operating
parameters, such as certain configuration items. Modify level commands are password-protected
and have predefined login names. See chapter 3 for Modify level command definitions.
Note: If a Modify level command is entered while at Monitor level, the message "Error: Bad
command Syntax:" will appear.
Global Commands
Global commands are basic commands (such as help) that are always available at the current
access level. Some global commands are available only in Modify access level mode (not Monitor
mode). For example, the command login is a Monitor access level global command. However,
logout is a Modify access level global command.
Example of Global Command Use
PROFINET Controller prompt in Modify level (not in Configuration mode):
device-name=
Enter help global to view available global commands at the Modify access level:
device-name= help global
alias - Text substitution
cls - Clear the screen
help - Show available commands
history - Show command history
log - Display local log table

Non-Global Commands
Non-Global commands are commands whose functionality varies at different access levels.
