*1: Has a meaning in the robot controller’s internal process as a dedicated input/output. This
cannot be used as a general-purpose input/output in the robot program.
*2: This area is reserved for the CC-Link system.
*3: Has a meaning in the robot controller’s internal process as a dedicated command region. This
cannot be used as a general-purpose input/output in the robot program.
An example of the flow of the I/O information in the robot controller (remote device
station) is shown below. The buffer memory in the master station used to store the infor-
mation, etc., differs according to the PLC type and station No., etc. Refer to the PLC
Manual for details.

NOTE
The dedicated input of the STD.DIO
connector provided on the controller
will be disabled except for an interlock
signal (DI 11). When the external 24V
monitor control of system parameters
is disabled, the interlock signal (DI 11)
will also be disabled.
