The functions of the system variables are briefly described in chapter 4.6.3. Some
of these variables are mentioned in the following chapters to be able to explain the
application programming.
4.27.1 Configuring the System
To run the programming software, you will need a PC that complies with the re-
quirements for a computer that runs with Windows95/WindowsNT (1) operating
system. One of the computer’s serial interfaces (COM1 or COM2) is connected
with the interface channel SER2 of the operating terminal using the download ca-
ble. The connection of the operating terminal to the PLC is established with an
additional, controller-specific interface cable. Care must be taken to ensure that the
correct type of interface cable is used and that the operating terminal is connected
to a power source which complies with the technical specifications for the operating
terminal.

Fig. 25: System configuration
Project execution can begin once all preparatory measures have been taken. All
functions provided by the operating terminal can be executed and tested with the
configuration shown above. If operated without a PLC (see simulation without
PLC), all operating functions with the exception of the PLC responses can be test-
ed.
