4.2.4 Setting the Configurable Digital I/O (TBCI1 - 4,TBCO1 - 4)
The digital I/O of the controller consists of 16 inputs and 16 outputs. They are used to connect
peripherals required for robot control or are set to dual safety I/O to be used for safety signal I/O
purposes.
The electrical specifications of the configurable digital I/O are as follows:
Caution
The VIO (IO 24V) and GIO (IO GND) terminals that can be used as power supplies for digital
I/O are separated from the VCC (24V) and GND of other power supplies on the safety I/O
circuit. Take caution as the diagnostic functions of the robot will detect errors if the internal
power supply is connected as a digital I/O power supply through the Terminal Block for Digital
I/O Power (TBPWR), or if 24V power is not supplied to the VIO and GIO terminals through an
external power supply, the configurable digital I/O does not work, and shuts off operating power
to the robot.
