Description
Self-diagnosis is performed when power is turned ON and periodically during opera-
tion. When an error occurs, it is treated as a fatal error, the MS indicator will light in
red, and all safety outputs and output data to the network will turn OFF.
After configuration data has been downloaded and verified, configuration data within
the DST1-series Safety I/O Terminals can be protected by a password.
The DST1-series Safety I/O Terminals is automatically set to the baud rate of the net-
work.
