Error queue
The error queue holds error and status messages. As programming errors and status messages
occur, a message that defines the error or status is placed in the error queue.
An error or status message is cleared from the error queue when it is read. You can also clear the
error queue by sending the command errorqueue.clear(). An empty error queue clears the error
available (EAV) bit in the Status Byte Register.
Messages in the error queue include a code number, message text, severity, and TSP-Link
number. See
When you read a single message from the error queue, the oldest message is read. If you attempt to
read the error queue when it is empty, the error number 0 and "No Error" is returned.
The commands that can be used to control the error queue are listed below.
