Caution

General digital I/O devices can stop at any time due to a controller power shortage, self-
diagnosis error detection and work program settings. Therefore, perform risk assessment
before setting up a robot workcell, and if additional risks such as a workpiece falling, ignoring
digital input or synchronization error due to incorrect recognition, make sure to implement
additional safety measures.

The general digital I/O is a single connection type I/O and any short circuits or breakdown can
result in the loss of safety functions, so it cannot be used for safety purposes. If the connection
of a safety device or safety-related I/O is required, make sure to set the corresponding terminal
as a dual safety I/O on the teach pendant.
