The Access over a telephone-line on the PLC could be configured in this dialog.
The Administrator could change the configuration over a telephone line, where an 2 User could not change
the configuration.
The User-Name is maximal 8 Chars long.Every user and the administrator could use a password which is
used to log into the PLC over a telephone-line. These have to enter for each new call.
After 3 wrong retries the connection is hanged up, so you must call again (Not so with an original TS-
adapter).
After changing the password for one user/administrator you must re-type it again correctly before it is
used.
In call-back-number you could define a telephone-number which is used for call-back from the TS-adapter.
After you connect with the TS-adapter, you are asked for your user-name and password. When the correct
password and user-name is transfered, the connection is hanged-up and the TS-adapter is calling back this
configured call-back-number.
