4 Requirements for the LON communication link for remote communication
The control terminal is normally always used in a Substation Automation
system. For that purpose, the LON communication link is connected to a
LON Star Coupler via optical fibres. The optical fibres are either glass or
plastic with the following specification:
Connect a PC as an MMI to this LON network. Windows NT runs on the
PC, which is equipped with a communication card for the LON (Echelon
PCLTA card). Control functions in the MMI (to be used with REC 561)
are available in the HV/Control software package, a library of standard
application functions, and pictures for the application engineering in
S.P.I.D.E.R. MicroSCADA ver. 8.4 or later.
To configure the nodes in a Substation Automation system you need the
LON Network Tool. This is a software package that runs under Microsoft
Windows 3.1 or higher or Windows NT. You can load the tool into a PC,
which is equipped with an Echelon PCLTA card or connected to an Eche-
lon SLTA card in the star coupler, with corresponding drivers.
5 Requirements for the SPA communication link for remote communication
The optical fibres that are supplied by ABB Network Partner AB fulfil all
the requirements for the communication in the station. You can use both
plastic fibres and glass fibres. For distances up to 30 m, use plastic fibres
and for distances up to 500 m, use glass fibres. You can mix glass and
plastic fibres in the same loop.
For communication on longer distances, use telephone modems. The
modems must be Hayes-compatible, which use AT commands with auto-
matic answering (AA) capability. The telephone network must comply
with the CCITT standards.
For connection of the optical fibre loop to a PC or a telephone modem you
need an opto/electrical converter. The converter uses RS232, and it has a
D25 connector on the electrical side. The converter is supplied by ABB
Network Partner AB.
The PC must comply with the requirements according to Buyer’s Guide
1MRK 511 014-BEN for SMS 010. For the CAP 531 configuration tool,
see User’s Guide 1MRK 511 034-UEN.
