Communications Protocols
Virtual File Interface
You can retrieve and send data as files through the relay virtual file interface.
Devices with embedded computers can also use the virtual file interface.
Send and receive files using the following three protocols:
FTP and MMS File Structure
The Ethernet File Transfer Protocol (FTP) and the IEC-61850 Manufacturing
Messaging Specification (MMS) have a two-level file structure. Files are
available at the root level and subdirectories. Tabl e 7 .5 6 shows the directories
and their contents.
Root Directory
The root directory (/) contains files and subdirectories as shown in Table 7.56.
CFG.TXT File (Read-Only). The CFG.TXT file contains general
configuration information about the relay and each settings class. External
support software retrieves the CFG.TXT file to interact automatically with the
relay. Calibration settings are included only when the file is read at Access
Level C.
1. File Transfer Protocol (FTP)- Ethernet Port only
2. MMS File Transfer - Ethernet Port only
3. Ymodem - Serial or Ethernet Ports
