IO structure Send Mode
This structure determines the trigger conditions the Web-IO
Analog-In/Out uses to send the state of the ports to the user
program. The trigger can be configured for state changes on
both ports. The respective hysteresis for the trigger must be
set in the Web configuration.

IO structure ReadDiagnosis
If the Web-IO detects a communications or system error, the
error is listed on the HTML page diag and can be read from the
browser. Since error management via browser is not always
available for program-controlled applications, the error status
of the Web-IO can be polled using the structure ReadDiagnosis.
