Monitoring the Error History
Description
The error history of a NE1A-SCPU01 or DST1-series Safety I/O Terminal can be monitored using the Net-
work Configurator.
Twenty error history records can be saved internally in a NE1A-SCPU01 and ten records in a DST1-series
Safety I/O Terminal. When the number of errors exceeds the number of records, the oldest records will be
deleted.
Depending on the error type, some errors are saved in non-volatile memory and not cleared when the power
is turned OFF. Other errors are saved in RAM and cleared when the power is turned OFF. Refer to the rele-
vant operation manual for details.
