SEL-2020 Instruction Manual
the settings have not yet compiled. ‘Running’ indicates that SET M settings exist and are
running on the designated port. ‘Disabled’ indicates that SET M settings exist but are not
running on the designated port; this is typically due to insufficient RAM. See Section 6:
Settings for a complete discussion of SET M settings.
Database Delays. The Database Delays column indicates in which database regions (e.g., D1
A1) data have not been collected at the desired rate since the last STATUS command was issued.
Any entry in this column indicates a request for data with a previous request pending. These
delays will occur: a) in transparent mode because the SEL-2020 cannot perform its data
collection operation, b) if the data collection rate is set too high for the IED response time, or c)
if the SEL-2020 is so busy that it cannot process data requests at the set rates.
STORE m:n d (Access Level 2)
Use the STORE command to store data directly into a database. Parameter m specifies the port
number (1 through 16); parameter n specifies the starting database address; and parameter d is a
data stream with each item consisting of data as characters, decimal integers, hexadecimal
integers, or single-precision floating-point numbers. You identify the data as character data by
placing the character(s) in single quotes (i.e., “F”), null-terminated string data by placing the
character(s) in double quotes (i.e., “G”). Decimal integer data are the default. Hexadecimal
integer data are indicated when the last character is an “h.” Floating-point data are indicated by
the presence of a decimal point (.) within the number.
Use the STORE command to force data into the database for test purposes. The database address
being accessed must be a valid database address for writing. You cannot write to read-only
addresses in the Global and Local Data Regions. You can write to any allocated User Data
Region. You set up the User Data Region for each port as a portion of the auto-message settings
(SET A). Use the VIEW command to confirm that data are stored as you expected.
The following example illustrates how you use the STORE command to store various types of
data and how you use the VIEW command to see the stored response:
*>>STORE 3:F800h ‘F’ 123 123h 123.<ENTER>
STORE 3:F800h ‘F’ 123 123h 123.<ENTER>STORE 3:F800h ‘F’ 123 123h 123.<ENTER>
STORE 3:F800h ‘F’ 123 123h 123.<ENTER>
*>>VIEW 3:F800h NR 5<ENTER>
VIEW 3:F800h NR 5<ENTER>VIEW 3:F800h NR 5<ENTER>
VIEW 3:F800h NR 5<ENTER>
3:F800h
0046h 007Bh 0123h 42F6h 0000h

SWAP n m (Access Level 2)
The SWAP command switches all port-specific settings (P, A, M, U, and L settings) between two
ports. The SEL-2020 requests confirmation, as for the COPY command. This command can
only be performed if neither of the two ports is currently communicating transparently. Before
performing the SWAP, the SEL-2020 requests confirmation. If you answer yes, the alarm
contact is pulsed and the involved ports are reset. Neither of the selected ports may be the
current port or Port F.
