Logon Data (definition)
A remote connection to a TS Adapter can only be successfully established if the
specified logon data (user name and password) for establishing a connection
matches the logon data stored in the TS Adapter.
Modem (Definition)
Modulator/Demodulator: A modem is a communication device that allows a
computer to send and receive data via phone lines.
It converts digital pulses of the computer into analog signals and vice versa.
Modem Connection
In the case of a modem connection, the connection between the programming
device or PC on which the TeleService is installed and the automation system onto
whose MPI/DP or Ethernet interface of the TS Adapter is plugged is implemented
via a modem connection. By this means the programming device/personal
computer is connected to the MPI/PROFIBUS network or Industrial Ethernet of the
automation system via the remote connection and the TS Adapter. The modem
connection is the usual configuration for working with the TeleService.
Multiple subscriber number (MSN)
If more than one terminal device (e.g. an ISDN phone and a TS Adapter II with an
integrated ISDN adapter) is connected to an ISDN multiple terminal connection
with the D-channel protocol DSS1 or 1TR6, you have to assign different multiple
subscriber numbers to these terminal devices.
Example: Two multiple subscriber numbers are available at one multiple terminal
connection:
• "121212" and
• "141414".
The ISDN phone should only react to calls for the number "121212" and the
number "141414" is reserved for a TS Adapter II ISDN. In order for the
TS Adapter II ISDN to only accept calls for the number "141414", set "DSS1,
1TR6" as the D-channel protocol in the "Internal ISDN-TA" dialog box. Additionally
enter the number "141414" in the "Multiple Subscriber Number" box.
If the multiple subscriber numbers are not entered, the integrated ISDN adapter
accepts all the calls.
Password
After a modem connection has been established the administrator or the users
have to enter a password during logging in.
