SICAM MMU 7KG9663, Device Manual
E50417-H1040-C514-A3, Edition 01.2016
Communication
To communicate with the control center and other process automation equipment, the device features an Ether-
net interface.
Ethernet supports the device parameterization, the transmission of measured data, counter values and indica-
tions and the time synchronization via NTP. The communication protocols are HTTP and Modbus TCP or
IEC 60870-5-104. At use of the protocol IEC 60870-5-104 two redundancy methods are supported.
Time Synchronization
During operation SICAM MMU needs the date and time for all time-relevant processes. This ensures that a
common time basis exists when communicating with peripheral devices and enables time stamping of the pro-
cess data. The following types of time synchronization can be executed:
•
External time synchronization via Ethernet NTP (preferred)
•
Internal time synchronization via RTC (if external time synchronization is not available)
Parameterization
No special software is needed for parameterization. You can set the parameters from your computer via HTML
pages and a web browser. Internet Explorer 6 (or higher) is necessary for this purpose.
