6.7 Usage Examples
The PLX8X-MNET-61850 is intended to work with and be highly integrated with
Schneider Electric Quantum and Premium PLCs, as well as M340 PACs. The
gateway creates files for the user to import into Unity Pro, Schneider Electric’s
PLC configuration software, to simplify setup and integration of the PLX8X-
MNET-61850 into Unity Pro.
The function block created by ProSoft 61850 Configuration Manager requires
Quantum processor firmware version 2.6 or later. However, if the customer is
using an NOE card for their Ethernet connection to the ProSoft gateway, then the
processor firmware version does not matter.
6.7.1 Example: Energy Application:
 The IEC 61850 protocol specification was written with electrical substations in
mind.
 The PLC wants ALL DATA, including time stamp and quality bits from all
IEDs. It will send this data to a dispatching system. In this case, the PLC is
like a data concentrator from the substation to the dispatching center.
 User wants Open and Close control with tight time constraints. The controls
need to be as fast as possible.
One typical example for this kind of application might be 20 IEDs, where the
ProSoft gateway needs to send all the data from all 20 IEDs to the PLC.
Typically, this would be approximately 50 data points per IED.
