Error status examples
(b) Considerations
• A request can be issued if the EN311 is in run mode, standby mode, or down
mode.
• For TCP open request, TCP receive request, or UDP receive request, if you
use the request with unrestraint wait, issue the reset request after changing
the operation mode to the standby mode.
