Entering the Administrator password in the variable
wtWebioEA12x12SessCntrlPassword
opens a session. Reading the variable
wtWebioEA12x12SessCntrlConfigMode
allows you to check whether the session was successfully opened.
1 = Session opened, Web-IO in configuration mode.
0 = Opening of the session failed. Check whether the password
was entered incorrectly.
After successfully opening the session you can make any
desired configuration changes or input and output accesses
using the variables defined in the Private MIB.
Once you are finished configuring, writing the variable
wtWebioEA12x12SessCntrlLogout
closes the session.
wtWebioEA12x12SessCntrlLogout =
1 All changes are saved
2 Quits without saving changes
If no SNMP communication takes place in an open session for
time of 5 minutes, the Web-IO ends the session and all changes
are cancelled.

Opening an SNMP session takes precedence over an
HTTP-Login. This means: A user having Administrator
rights loses his browser access as soon as an SNMP session is
opened.
The description for the individual SNMP variables, OIDs etc. can
be found in the Private MIB.
