The PROFIBUS DP protocol facilitates the connection of SIPROTEC
®
–devices to
SPS-based process control systems (e.g. SIMATIC S5/S7). The protocols DNP3.0
and MODBUS ASCII/RTU allow the connection to a wide range of control systems by
other manufacturers.

The devices in the SIPROTEC
®
4 family are delivered with default settings. After set-
tings are made for specific applications, the devices are suitable for direct use in power
systems.
