3.7 Address Configuration
ROBONET addresses are configured in the same manner with all four types of gateway units regardless of the type of field
network.
The addresses occupied by the network consist of a fixed 8-word area and a data area that changes according to the
operation mode and number of axes. The operation modes and occupied data areas are shown below.
The positioner 1 mode, simple direct mode and direct numerical specification mode can be combined, and a desired mode can
be selected for each axis. Also note that the positioner 2 mode, solenoid valve mode 1 and solenoid valve mode 2 cannot be
combined with the positioner 1 mode, simple direct mode or direct numerical specification mode.
