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 applications 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 network 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 password.
