MiCOM S1 and MiCOM S1 Studio relay communications basics 

MiCOM S1 Studio is  the universal MiCOM IED Support Softwares and provide users a 
direct and convenient access to all stored data in any MiCOM IED using the EIA(RS)232 
front communication port. 

MiCOM S1 Studio provides full access to

: 

−

  MiCOM Px20, Px30, Px40 relays 

−

  MiCOM Mx20 measurements units 

The following sections give the main procedures to connect and to use MiCOM S1 Studio. 

Before starting, verify that the EIA(RS)232 serial cable is properly connected to the 
EIA(RS)232 port on the front panel of the relay. Please follow the instructions in section 3.1 
to ensure a proper connection is made between the PC and the relay before attempting to 
communicate with the relay. 

This section is intended as a quick start guide to using MiCOM S1 Studio, and assumes you 
have a copy of MiCOM S1 Studio installed on your PC. Please refer to the MiCOM S1 Studio 
User Manual for more detailed information

.

MiCOM S1 Studio 

3.5.1 

Data Model Management 

The settings and parameters of the protection relay can be extracted from the relay or 
loaded usin Fata Model manager. The Data Model Manager can load any model from Local 
file, CD ROM or Internet server (if connected). 

The Data Model Manager is used to add or to remove data models, to export and to import 
data model files. 

It is necessary to close MiCOM S1 Studio when the Data Model Manager is opened. 

To Open Data Model manager, click on the icon: 

. Select "MiCOM S1 Studio" then 

"Data Model Manager" in the "Programs" menu.
