2.1.2 Setting guidelines
M11876-3 v7
SPA, IEC 60870-5-103 and DNP3 use the same rear communication port. This port can be set
for SPA use on the local HMI under Main menu /Configuration /Communication /Station
communication/Port configuration/SLM optical serial port/PROTOCOL:1. When the
communication protocol is selected, the IED is automatically restarted, and the port then
operates as a SPA port.
The SPA communication setting parameters are set on the local HMI under Main menu/
Configuration/Communication/Station communication/SPA/SPA:1.
The most important SPA communication setting parameters are
SlaveAddress
and
BaudRate
.
They are essential for all communication contact to the IED.
SlaveAddress
and
BaudRate
can
be set only on the local HMI for rear and front channel communication.
SlaveAddress
can be set to any value between 1–899 as long as the slave number is unique
within the used SPA loop.
BaudRate
(communication speed) can be set between 300–38400
baud.
BaudRate
should be the same for the whole station although different communication
speeds in a loop are possible. If different communication speeds are used in the same fiber
optical loop or RS485 network, take this into account when making the communication setup
in the communication master (the PC).
With local fiber optic communication, communication speed is usually set to 19200 or 38400
baud. With telephone communication, the speed setting depends on the quality of the
connection and the type of modem used. Refer to technical data to determine the rated
communication speed for the selected communication interfaces.
The IED does not adapt its speed to the actual communication conditions
because the communication speed is set on the local HMI.
