2.17.9.3 Operating Modes

The Web Monitor works in the following operating modes between the operator PC and the SIPROTEC 4
device:
Direct Serial Connection
Direct connection of the front operator interface or the rear service interface of the device with the serial inter-
face of the operator PC. For this link the 9-pin cable must be used that is supplied as an accessory with DIGSI.
Optional Connection via Modem
Serial connection of the rear service interface of the device with a modem in the system. This connection can
be electrically implemented via RS232 (over short distance) or via fiber optics. The connection to the system
modem is established from the office or from any other system using a switched line. DIGSI-Remote can also
be carried out using this connection. Thus, parameters of a remote device can also be changed during the in-
stallation.
Operation with Star Coupler
Connection of the rear service interface of the device via a direct optical connection to a star coupler. Connec-
tion of the operator PC's serial interface to a star coupler. In this way several devices can be operated within
the system; the existing installation can be used for central operation of protection devices.
Operation via Ethernet
Connection via an Ethernet interface. This type of connection requires an EN100 communication module inside
the device and a connection of that module to a local network.
