1-2 PACSystems* RX3i PROFINET Controller Command Line Interface Manual – July 2011 GFK-2572
Accessing the Command Line Interface
A computer can access the PROFINET Controller’s Command Line Interface either through the
module’s built-in Micro USB port or through the PROFINET network, using telnet with a terminal
emulation application such as HyperTerminal.
When connecting through the Micro USB port, a driver compatible with the PROFINET Controller’s
Micro USB port must first be installed as described in the PROFINET Controller Manual, GFK-2571.
Setting Up Telnet on the PROFINET Controller
A computer’s terminal emulation application can be used to communicate with the PROFINET
Controller via telnet. Telnet is initially disabled on the PROFINET Controller. It can be enabled by
connecting a Windows-based computer to the module’s Micro USB port, entering the telnetd
Command Line Interface command, and power-cycling the module.
Telnet functionality is accessed through port number 23.
Serial port settings must be 115200 baud, 8-None-1, with no flow control.
Once telnet has been enabled, it remains enabled through power cycles unless it is disabled again
using the telnetd Command Line Interface.
Note: If the PNC is power cycled or reset an established terminal emulation connection will
cease to work. Performing a manual Disconnect/Connect operation in the terminal
emulation program will restore operation of the connection.
Terminating a Command Line Interface Session
A Command Line Interface session terminates if:
1. the terminate command is entered.
2. the terminal application is disconnected, either physically or by command.
3. the session becomes inactive. The Command Line Interface automatically disconnects if the
session has remained inactive for the timeout period. The inactivity timeout value can be viewed
with the show sessionTimeout command. The default timeout, 600 seconds (10 minutes), can be
changed using the modify-level sessionTimeout command.
Terminal-related parameters (such as display settings and Alias values) that have been established
during a Telnet session are lost when the Telnet session is terminated. However, terminal-related
parameters that are established using the Command Line Interface are retained until the next power
cycle / restart.
