SICAM AI Unit 7XV5674, Product Information
E50417-B1150-C492-A1, Edition 09.2012
To communicate with the control center and other
peripheral devices, the device features an Ethernet
interface and optionally a serial interface (RS485 or
optical).
Via Ethernet, the following functions are supported:
• Device parameterization
• Transmission of measured data
• Transmission of indications
• Time synchronization via NTP
The communication protocols are HTTP and Modbus
TCP or IEC 61850.
The serial interface as RS485 or optical interface sup-
ports the following functions:
• Transmission of measured data
• Transmission of indications
• Time synchronization via fieldbus
Depending on the device version, you can use either
the Modbus RTU or the SIPROTEC RTU 20 mA
communication protocol.
The integrated Web server allows the user to configure
the parameters via HTML pages using a Web browser.
With the Ethernet switch that is integrated in the device,
further network components can be cascaded via a Y
cable, and can therefore also be incorporated in an
existing network with IEC 61850 or an other Ethernet
protocol.
NOTE
The communication protocol
SIPROTEC RTU 20 mA
is only supported by
SIPROTEC 4
