Begin typing in the address of the contacts you have highlighted or select a space that has nothing and press one of the soft keys to add a device.

The age on the control and whether it has the option to do so. whether the ladder can be edited through the control depends on two things. Not all Fanuc ladders can be edited on the machine.
