Note: The Occupied Area stands for the area occupied by means of the setting of the number of remote device
stations.
The System Area stands for the system area of the remote device station.
These areas are not used for any other purpose. Also take care about duplicating the use of the data register.
(2) I/O Signal Allocation for each Axis
The I/O signals for each axis consists of 1 word for each I/O bit register.
z
The I/O bit register is controlled using the ON/OFF signal in units of bit.
