This softkey offers further functions for diagnostics and start–up of the PLC.
Use this softkey to open the configuring dialog for the interface parameters for the STEP 7
connection.
If the RS232 interface is already occupied by the data transfer, you can connect the control
system to the Programming Tool only if the transmission is completed.
The RS232 interface is initialized with activation of the connection.

The baud rate is set using the toggle field. The following values are possible: 9600 / 19200 /
38400 / 57600 / 115200.
Use this softkey to activate the connection between the control system and the PC/PG. It is
waited for the call of the Programming Tool. Any modifications to the settings are not possi-
ble in this status.
The softkey labeling changes to <Connect off>.
You can cancel the transmission from the control system at any point by selecting <Connect
off > . Now it is possible again to make changes in the settings.
The active or inactive state is kept even after Power On (except power-up with the default
data). An active connection is displayed by a symbol in the status bar (cf. Table 1-2).
Press <RECALL> to quit the menu.
