If you want to change settings (IP address, subnet mask, etc.)

wtWebGraphAnalog57662SessCntrlPassword

opens a session. Reading out the variable

wtWebGraphAnalog57661SessCntrlConfigMode

allows you to check whether the session was successfully

opened.

1 = Session open, device in configuration mode.

0 = Session opening failed. Check whether the password may

have been incorrectly entered.

After successfully opening the session you can use the variab-

After configuration is finished, write the variable

wtWebGraphAnalog57661SessCntrlLogout

to close the session

wtWebGraphAnalog57661SessCntrlLogout =
