Configuring Relay Serial Data Communication - Siemens 7SR10 Argus Series Manual

2.1.3

Configuring Relay Serial Data Communication

Using the keys on the relay fascia scroll down the settings menus into the 'communications' menu and if
necessary change the settings for the communication port you are using on the relay. Reydisp software uses
IEC60870-5-103 protocol to communicate.
When connecting the relay to a pc using the front USB port, the Reydisp setting software will automatically detect
the relay without making any setting changes in the relay first as long as the USB is selected to IEC60870-5-103.
