Revision: A
Hardware
•
A metal protecting cap has been added to the LC connectors for the Long-Distance Protection
Communication and for the Ethernet / TCP/IP via fiber optics. Since the cap improves the EMC immunity it
is recommended to always fasten it carefully after plugging in the LC connectors.
•
There is a new communication type “T” available:
RS485 (IEC 60870-5-103, MODBUS RTU, DNP3.0 RTU)
+ RJ45 Ethernet 100 Mbit/s (IEC 61850, Modbus TCP, DNP3.0 TCP/UDP)
Software
•
The device firmware is also available in Romanian language now.
•
If the MCDLV4 is connected to
Smart view as of version 4.50 the synchronization of date and considers
automatically that the timezone settings might be different on PC and MCDLV4.
Communication
The menu [Device Para / HMI / Security] now makes the following setting parameters available:
•
»Smart view via Eth« activates or deactivates the access of Smart view via Ethernet.
•
»Smart view via USB« activates or deactivates the access of Smart view via the USB interface.
•
»Sm. view via ProtCom« activates or deactivates the access of Smart view onto the remote Line Differential
device via Protection Communication.
IEC60870-5-103
This communication protocol now supports the blocking of the transmission in Monitor Direction and the test mode.
Modbus
The transmission of fault values via Modbus protocol has been added. For the last fault event, all fault values are
accessible with addresses above 50000. For each fault value, the Modbus address corresponds to the address of
the respective instantaneous value shifted by the offset 30000. (Example: The current value IE1 has the address
20100, therefore the corresponding fault value has the address 50100.) For a detailed list, please consult the
SCADA documentation.
For devices with RS485
and Ethernet interfaces (communication types “I” or “T”), the project setting
„Modbus RTU/TCP“ is available now (via parameter [Device Planning] »Scada . Protocol«).
This makes the device communicate via serial line (RTU) and Ethernet (TCP) in parallel. In particular, note that:
•
All masters see the same set of states.
•
All masters can reset latched states.
•
All masters can control the same breaker, make resets and acknowledgments.
Device Para
The Reset dialog, that starts when the »C« key is pressed during a cold start, has been adapted to new security-
related requests: Now there is a new setting parameter
»Reset Options« that allows to remove options from the
Reset dialog.
Overcurrent – I[n], IG[n]
All ANSI and IEC inverse time characteristics have a time limit now according to IEC 60255-151. (See ➦
PhaseOvercurrent_Characteristics, ➦ EarthOvercurrent_Characteristics.)
A new inverse time characteristic “RINV” has been added.
