Error History
Section 10-4
10-4 Error History
The error history records errors that the NE1A-series Controller detects in the
total operating time of the Controller.
The error history can be read from the Network Configurator.
10-4-1 Error History Table
Error History Table
When an error is detected in a Pre-Ver. 1.0 NE1A-series Controller, the error
is recorded in the error history table in the RAM of the Controller. The error
history contains one record per error and can hold up to 20 records. If the
error history table already contains 20 records, the oldest record is deleted
and the new error data is stored.
When an error is detected in a NE1A-series Controller with unit version 1.0 or
later, the error is recorded in the error history table in the RAM of the Control-
ler. The error history contains one record per error and can hold up to 100
records. If the error history table already contains 100 records, the oldest
record is deleted and the new error data is stored.
The following information is stored in the error history table:
• Status information when an error occurs
• The time when an error occurs (total operating time of the NE1A-series
Controller)
• The node address where the error occurred or the error response value
(when an explicit message is sent)
Error History Saving Area
The description of an error is recorded as an error history in the NE1A-series
Controller’s RAM, and if the error is critical, it is also saved in the nonvolatile
memory. The error history recorded in nonvolatile memory is retained even
when the power supply of the Controller is not supplied or restarted. The error
history in the nonvolatile memory is copied to the RAM at the start of the Con-
troller’s power cycle.
The error history in RAM is read when reading the error history from the Net-
work Configurator. When clearing the error history, however, the error history
in both the RAM and nonvolatile memory are cleared.
Reading and Clearing the Error History Table
The error history can be displayed in realtime using the Error History Display
function of the Network Configurator. The error history data can also be saved
on the computer.
Note
(1) The total operating time of the NE1A-series Controller is recorded as the
accumulated time in 6-minutes increments while the power supply for the
internal circuit is ON. The total operating time is cleared using a Control-
ler Reset Command addressed to the NE1A-series Controller to clear all
or only specified variables to their default settings.
(2) When the error history is read from the Network Configurator, the node
address where the error occurred or the error response value is displayed
as manufacturer-specific ALARM exception detail [7] 0x**.
(3) When the NE1A-series Controller’s error history is read from the Network
Configurator, both the error status information and the node address
where the error occurred or the error response value are displayed for
each error history record.
