This area shows the station address, input byte length, and output byte length for
each slave station. This allocation is set by the GX Configrator-DP. The station
addresses for the 1st through the 60th stations are stored in the order of
registration in the GX Configrator-DP. (Station addresses: 1 to 126, do not need
to be sequential numbers.)
The address information area configuration is shown below. For details refer to
Section 3.4.2 (4).
