4.6.1 Serial Ports
Serial PC port
PC Port and service
port
The central unit of 7SS52 V4 features one or more serial ports: one operating interface
integrated in the front panel, also called PC port, and one rear service port and system
port for connection to a control center. Communication via this port is subject to certain
agreements concerning the device identification, the transmission format and the
transmission rate.
These ports are configured via the DIGSI communication software. Click Settings on
the navigation window. Then click Serial ports in the data window and enter your spe-
cific data into the dialog box that opens (Figure 4-22, page 71). Depending on the
model of the device, the dialog box has different tabs with setting options for the cor-
responding interface parameters which you can access successively by mouse click.
Figure 4-22 DIGSI, settings of the PC port
Indicate on the first tab sheet (Serial port on PC) the communication port of your PC
connected to 7SS52 V4 (COM 1 or COM 2 etc.). You do not have to enter manually
the settings for the data format and for the baudrate. You can take over the values
from the tab Operator interface or, if available, from the tab Service interface. In do-
ing so DIGSI reads out important settings directly from the interface and the corre-
sponding boxes are grayed (see Figure 4-22, page 71). Or you can enter individual
values at the option Independent of device.
The tab sheets Operator interface and Service interface provide setting options for
the data format, the baudrate and also for the IEC link address and maximum mes-
sage gap (example given in Figure 4-23, page 72).
