AC700F IP Address Configuration
Looking at moving a new project onto our network so I am able to test on various operator stations throughout the office. Just struggling to find some information on how the AC700 IP address can be modified through the diagnostics port?
Basically looking to change everything onto 10.0.22.xx with a 255.255.255.0 subnet from the standard 172.16.xx.xx.
Any help would be appreciated.
It’s a special case of IP address setting, use diagnostic cable to connect with Controller diag port, user HyperTerminal or Tera Term pro(in case of W7) to access the controller configuration messages.
Hit enter if you are getting some text means you are connected with controller. If not check settings.
Now Press reset button on controller for little longer time (>5 sec) until you can see some changes at run led. Then as controller starts keep on hitting <SPACE> key until text update stops (i.e bootloader configuration enters into input menu )
You can find instructions C – change, T- time, S- save, B- boot.
Press C and you will enter into change mode where you can set IP and subnet mask and other settings,
After changing address press S-Save, and Press B-Boot.
Recommended taking help of some expert from ABB in setting up IP or use document 2PAA103858R0201_M&I_AC700F.pdf before proceeding for configuration.
Note that subnet 255.255.240.0 is needed for time synch. Check this link on AKS @
1.Connect Serial cable between AC700F controller and PC
