Teleservice via Callback function
With Callback there is the possibility to call the TM-E module with a defined
number of ring signals to initiate the callback mode.
Now the module accesses the Internet and sends an eMail, which contains
in its text a dynamic PPP IP address. This address may be accessed as
long as the TM-E module is online. So you may safe money for connection,
if e.g. the plant to be observed is abroad.
The configuration of the Callback mode happens on the Web page of the
TM-E module with the following approach:
•
Configuration of the direct telephone connection
•
Configuration of the dial-up server
•
Configuration of the mail server
•
Activation of the Callback
For the further proceeding it is precondition you have access to the Web
page of the TM-E module and your CPU is connected to the TM-E module
and accordingly configured.
Further it is precondition that a SIM card installed and your TM-E module is
connected to the mobile network.
If you have just established the teleservice via telephone, please continue
with the configuration of the dial-up server.
With the teleservice via telephone a connection via telephone (PPP
connection) is directly established from your PC to the TM-E module.
To be able to react to the calling, to authenticate the user and to assign the
IP address, the TM-E module is to be configured as PPP server.
