Details
Entries are stored in a first-in, first-out (FIFO) queue. This function reads the oldest entry and
removes it from the queue.
Error codes and messages are listed in the Error summary list (on page 12-9).
If there are no entries in the queue, code 0, "Queue is Empty" is returned.
Returned severity levels are described in the following table.
Severity level descriptions
Indicates that there are no entries in the queue.
Indicates a status message or minor error.
Indicates possible invalid user input; operation continues but action
should be taken to correct the error.
Indicates a serious error that may require technical assistance, such as
corrupted data.
Instrument is not operational.
In an expanded system, each TSP-Link enabled instrument is assigned a node number. The variable
errorNode stores the node number where the error originated.
Example
errorcode, message = errorqueue.next()
print(errorcode, message)
