IEC 61850 Networks for PACSystems
IEC 61850 is an international standard for the design of electrical substation automation
that defines the communication between electrical switchgear and substation control
equipment. An IEC 61850 Client connects to and communicates with multiple Intelligent
Electronic Devices (IEDs, or IEC 61850 Servers) over an IEC 61850 network. This enables
configuration, parameterization, and diagnostics communication between controllers and
devices.
Note:
The ECM850 operates only in auto negotiate mode. All bus devices and switches that are
connected to the module should be configured to use auto negotiation.

PAC Machine Edition Configuration and Programming
Machine Edition is used to co
nfigure the ECM850’s IEC 61850 client system. The IEC 61850
connectivity configuration with IEDs and selection of IEC 61850 data objects and attributes
can be done using an integrated IEC 61850 Configurator in the Machine Edition. The
Machine Edition application automatically generates PLC Protocol Variables (PPVs) in the
object-oriented model. These PPVs are available in controller programs as CPU symbolic
variables, enabling the RX3i controller to control, monitor, and sequence the operation of
IEDs using these variables.
Machine Edition provides two methods of configuring an ECM850: online and offline.
Online Configuration: The IEC 61850 data model can be directly read from the IED over the
IEC 61850 network if the IED is connected to same network as the computer on which
Machine Edition is installed. The Configurator provides a mechanism to then browse the
data model of the device and select data objects and data attributes (DO/DA) for the RX3i
controller.
Offline Configuration: The IEC 61850 data model can be directly read or imported from an
IED configuration file (ICD or CID file). The Configurator provides a mechanism to then
browse the data model of the device and select data objects/attributes for the controller.
Note:
Adding variables manually in the IEC 61850 Configurator is not recommended, as this may
result in incorrect configuration and validation errors.
The detailed configuration procedure and mechanism is described in Chapter 3 and is also
available in Machine Edition online help.
The next illustration shows a programmer connection (for configuration, user logic
programming, and monitoring), the concept of variable Configuration import, an optional
external Ethernet switch, and the ability of ECM850 to connect to an IEC 61850 IED
