•
File Transfer Enabled: Specifies whether the file transfer function is enabled
•
File Transfer Source Directory: Defines the source directory for the disturbance
recording files. Default is C:\COMTRADE
File names in IEC101 file transfer are built from two numbers; IOA (Information object
address) and NOF (name of file). For NOF a running number (1..0xFFFF) is used. For
IOA, a unique number assigned to each source IED is used. The IOA is assigned with
the File Transfer function of the Cross-References function. There must be at least one
cross referenced signal from the IED, which must be included in the file transfer handling.
When the File Transfer dialog is opened from the Cross-References function, it shows
the source IEDs, which can be used for the file transfer. The Information Object Address
is automatically assigned by the tool, but it can be manually changed if necessary .
All files belonging to the same disturbance recording are zipped into a single file, which
is offered to the IEC 101 master. Only one file is offered at a time. When the file is
transferred successfully, the next recording if available is offered. In the master system,
the received file should be renamed with zip extension and unzipped to access the con-
tents.
Transparent SPA function
COM600 supports encapsulated SPA telegrams over IEC 101 communication. It enables
IEC101 master systems with SPA support accessing SPA parameters of IEDs connected
to COM600. The IEC information address used for the SPA telegrams is configured
using the Transparent SPA of the Cross-References function. There must be at least one
cross referenced signal from the IED, which must be included in Transparent SPA
handling. When the Transparent SPA dialog is opened from the Cross-References func-
tion, it shows the source IEDs which can be used for transparent SPA access. The
Information Object Address for each source IED is assigned in the table of the dialog.
Configuring objects
General about configuring objects
After the objects have been added, configure the object properties. Figure 3.4.1-1 shows
an example of how to use SAB600 to configure the object properties for IEC101 Slave
OPC Client.
To configure an object:
1. Select an object in the object tree of the communication structure.
