Monitoring the Error History
Description
Monitoring Using the Network Configurator
208
The error history of an NE1A-series or NE0A-series Controller or DST1-series
Safety I/O Terminal can be monitored using the Network Configurator.
Twenty error history records can be saved internally in a Pre-Ver. 1.0 NE1A-
series Controller, 100 records if the unit version is 1.0 or higher (including the
NE1A-SCPU01-EIP and NE1A-SCPU02-EIP), 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 relevant operation
manual for details.
The user can monitor the error history using any of the following methods:
1. Select a device and select Device – Monitor from the menu bar. Click the
Error History Tab in the displayed window.
2. Select a device and click the Monitor Device Button on the toolbar. Click
the Error History Tab in the displayed window.
3. Right-click a device and select Monitor from the pop-up menu. Click the
Error History Tab in the displayed window.
