Products
ST-IPm-6350\DA50A\DA70A
Use Case:
When a ST-IPm-6350 is connected to a FlexEdge the ST-IPm-6350 can reboot the FlexEdge if necessary. This document describes ST-IPm-6350 Network 2 port connected to FlexEdge Ethernet 2 port.
- ST-IPm-6350 Network 2 port IP address = 192.168.222.1\24
- FlexEdge Ethernet 2 port IP address = 192.168.222.222\24
Required Software
Sixnet I/O Tool Kit version 5.0.103 or later
Crimson 3.2.0043.0 or later
ISaGRAF 3.47 or above
Configure Reboot watchdog and configure Firewall in the FlexEdge
-
Enable Reboot with port and password. In Crimson 3.2 go to Device Configuration>System Configuration>Services>Watchdog. Enable Remote Reboot. Set the Listen Port to a free port. In this case, the port is set to 777. Set the Password. In this case, the password is set to 444.
-
Open Remote Reboot port on the FlexEdge. Go to Device Configuration>System Configuration>Network>Firewall>Untrusted Traffic. In the ‘Custom’ tab add a white list port. Add a label (meaningful name). Set the port to ‘Ethernet 2.’ Set Protocol to ‘TCP.’ Set ‘Start Port‘ and ‘End Port’ to 777 (matches the Remote Reboot Listen port).
Send Reboot command manually from ST-IPm-6350 to the FlexEdge
-
Enable User Authentication in the ST-IPm-6350. In the Sixnet I/O Tool Kit go to Configure>Configure Station/Module in the General tab go to Configure Users. Enable user authentication. Set anonymous user to have NO permissions. Click Add User button with all the permissions and set user name and password,
-
Enable Telnet and/or SSH in the ST-IPm-6350. In the Sixnet I/O Tool Kit go to Configure>Configure Station/Module in the Advanced tab and in Services enable Telnet. Load the configuration to the ST-IPm-6350.
- Telnet to the ST-IPm-6350. Connect PC to the ST-IPm-6350. Using a terminal program enter ‘Telnet <IP address>’ where ‘<IP address>’ is either Network 1 or Network 2 configured IP address. When the telnet session begins log in using the configured user.
- Type the reboot commands and telnet string. The string is ‘( sleep 1 && echo -n -e "<Remote Reboot password>\r" && sleep 1 && echo -n -e "REBOOT\r"; ) | nc <ip address> <Remote Reboot Listen Port>’ In this test with the configurations used in this configuration is ‘( sleep 1 && echo -n -e "444\r" && sleep 1 && echo -n -e "REBOOT\r"; ) | nc 192.168.222.222 777’
Send Reboot command with ISaGRAF with sxlaunch function
Alternatively, the reboot command can be triggered with discrete bit using the sxlaunch function block. The sxlaunch function block can send any linux command. Sending the telnet string above by entering it as a string variable in Red Lion Workbench.
- Create a script file with the command line as shown below. Give the script file permissions to be executed. In this case the file is named ‘DA70_Reboot’ in the root directory: ‘( sleep 1 && echo -n -e "444\r" && sleep 1 && echo -n -e "REBOOT\r"; ) | nc 192.168.222.222 777’
- The sxlaunch function is used in ISaGRAF to execute the ‘DA70_reboot’ file. lathe function to triggerThe command Trigger telnet string with the sxlaunch function block. Add the sxlaunch function block to the Red Lion Workbench program. The RunControl input is a Boolean input and can be triggered in a variety of ways. In this case “Trigger_Reboot” is a discrete input variable to trigger the execution.
- The “PathOfApplication” input is the telnet string defined above surrounded in single quotes making it a message variable. In this case ‘/DA70_Reboot’ was used to execute the file. Outputs on the sxlaunch block are optional.
