Communication
The following interfaces are available for communication with external operating, control and memory systems.
The USB DIGSI interface on the front cover serves for local communication with a PC. By means of the
SIPROTEC 4 operating software DIGSI, all operational and evaluation tasks can be executed via this operator
interface, such as specifying and modifying configuration parameters and settings, configuring user-specific
logic functions, retrieving operational messages and measured values, inquiring device conditions and mea-
sured values, issuing control commands.
Depending on the ordered variant, additional interfaces are located at the bottom of the device. They serve for
establishing extensive communication with other digital operating, control and memory components:
Port A serves for DIGSI communication directly on the device or via a network.
Port B serves for central communication between the device and a control center. It can be operated via data
lines or fiber optic cables. For the data transfer, there are standard protocols in accordance with IEC 60870-5-
103 available. The integration of the devices into the SINAUT LSA and SICAM automation systems can also
be implemented with this profile.
Alternatively, there are further coupling options possible with PROFIBUS DP and the DNP3.0 and MODBUS
protocols. If an EN100 module is available, it is also possible to use the IEC61850 protocol.
