Internal events
Basic
Internal events are generated by the built-in supervisory functions. The
supervisory functions supervise the status of the various modules in the
terminal and, in case of failure, a corresponding event is generated. Simi-
larly, when the failure is corrected, a corresponding event is generated.
Apart from the built-in supervision of the various modules, events are also
generated when these functions change status:
• Built-in real time clock (in operation/out of order)
• External time synchronization (in operation/out of order)
Events are also generated on these occasions:
• Whenever any setting in the terminal is changed
• When the content of the Disturbance report is erased
The internal events are time tagged with a resolution of 1 ms and stored in
a list. The list can store up to 40 events. The list is based on the FIFO prin-
ciple, when it is full, the oldest event is overwritten. The list cannot be
cleared; its content cannot be erased.
The list of internal events provides valuable information, which can be
used during commissioning and during fault tracing.
The information can only be retrieved with the aid of the SM/REx 5xx
software package. The PC can be connected either to the port at the front
or at the rear of the terminal.
The internal events list is available under the:
