Direct Connection (Definition)
In the case of a direct connection there is a direct connection between the
programming device/personal computer on which TeleService is installed and the
automation system via the TS Adapter. No modem is required to this purpose. The
direct connection is used essentially to configure the TS Adapter.
With the TS Adapter I, the direct connection is over the serial port; the
TS Adapter II uses the Universal Serial Bus (USB) and the TS Adapter IE uses
Industrial Ethernet.
Folder
Folders are used in TeleService to manage plants in which specific data on
establishing remote connections are saved. Folders are managed in phone books.
GSM

Initialization String (Definition)
The initialization string is a string consisting of AT commands (quasi-standard
commands for modems) with which the modem connected to the TS Adapter is
initialized.
Interface Speed
The interface speed is the speed with which the data are transferred between two
devices, for example between the modem and the TS Adapter.
