Hardware and software modules
The hardware needed for applying LON communication depends on the application, but one
very central unit needed is the LON Star Coupler and optical fibers connecting the star coupler
to the IEDs. To interface the IEDs from the MicroSCADA with Classic Monitor, application
library LIB520 is required.
The HV Control 670 software module is included in the LIB520 high-voltage process package,
which is a part of the Application Software Library in MicroSCADA applications.
The HV Control 670 software module is used for control functions in the IEDs. The module
contains a process picture, dialogues and a tool to generate a process database for the
control application in MicroSCADA.
When using MicroSCADA Monitor Pro instead of the Classic Monitor, SA LIB is used together
with 670 series Object Type files.
Use the LON Network Tool (LNT) to set the LON communication. This is a software tool
applied as one node on the LON bus. To communicate via LON, the IEDs need to know
• The node addresses of the other connected IEDs.
• The network variable selectors to be used.
This is organized by LNT.
The node address is transferred to LNT via the local HMI by setting the parameter
ServicePinMsg = Yes . The node address is sent to LNT via the LON bus, or LNT can scan the
network for new nodes.
The communication speed of the LON bus is set to the default of 1.25 Mbit/s. This can be
changed by LNT.

Application

The IED provides two function blocks enabling several IEDs to send and receive signals via the
interbay bus. The sending function block, MULTICMDSND, takes 16 binary inputs. LON enables
these to be transmitted to the equivalent receiving function block, MULTICMDRCV, which has
16 binary outputs.
Application manual
The HV Control 670 software module and 670 series Object Type files are used
with both 650 and 670 series IEDs.
