System Startup and Error Recovery Support
• Error information can be checked by using the error log function or the
indicators on the front of the DST1-series Safety I/O Terminals.
• The DST1-series Safety I/O Terminal’s safety I/O data and internal status

mation in the standard Master. In the same way, the information can be
monitored from a safety PLC by allocating the information in the Safety
Master.

tions, such as a contact operation counter and cumulative ON time monitor.
