The error history records errors that the ED Router detects, along with the
total operating time of the ED Router. The results recorded in the error history
can then be read or cleared from the Network Configurator.
Depending on the contents of the error history, some parts are cleared and
some are not cleared when the CPU Unit power is turned OFF or reset.
When an error is detected in the ED Router, the error is recorded in the error
history table in the RAM of the ED Router. The error history contains one
record per error and can hold up to 64 records. If the error history table
already contains 64 records, the oldest record is deleted and the new error
data is stored.
The following information is stored in the error history table:
• Time that error occurred (total ED Router operating time)
• Error information
• Detailed information
The description of an error is recorded in the error history in the RAM of the
ED Router, and if the error is critical, it is also saved in the nonvolatile mem-
ory. The error history recorded in nonvolatile memory is retained even when
the power supply of the ED Router is not supplied or restarted. The error his-
tory in the nonvolatile memory is copied to the RAM at the start of the ED
Router 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.
The error history can be displayed in realtime using the Error History Display
function of the Network Configurator. (Select the device, and then select
Device - Monitor.) The error history data can also be saved on the computer.
The total operating time of the ED Router is recorded as the accumulated time
in 6-minute increments while the power supply for the internal circuit is ON.
