DST1-series Safety I/O Terminals
Safe State
The following status is treated as the safe state by the DST1-series Safety I/O
Terminals.
• Safety outputs: OFF
• Output data to network: OFF
Therefore, the DST1-series Safety I/O Terminals must be used for applica-
tions in which it enters into safe state when the safety outputs turn OFF and
the output data to the network turns OFF.
Self-diagnosis Functions
Self-diagnosis is performed when the power is turned ON and periodically
during operation. If an error occurs, it will be treated as a fatal error (the MS
indicator will light in red), and the safety outputs and output data to the net-
work will turn OFF.
Access Control by Password
After configuration data had been downloaded and verified, the configuration
data within the DST1-series Safety I/O Terminals can be protected by a pass-
word.
