Data Access
Step 3. Use “20 message” commands to collect SEL relay data.
When relay data are available in the SEL-2030, the SEL-2701 will
automatically collect data from the Data regions and use it to populate
available models.
For non-SEL IEDs, the SEL-2701 populates models based on user-entered
database register element labels. To populate GOMSFE models for non-SEL
IEDs use the following steps:
Step 1. Configure the SEL-2030 to collect data from the IED into
database regions.
Step 2. Transfer the data into the SEL-2030 User region using Math/
Data Movement commands (SET M) and label with the labels
listed in Appendix B.
Step 3. The SEL-2701 will automatically collect data from the labeled
registers and use it to populate the available models.
Generic Analog Data
The SEL-2701 maps up to 64 analog values to each GLOBE model. The
SEL-2701 maps data in the User region with the labels ANALOG01–
ANALOG64 to the MX functional component of GLOBE. Only the data that
are labeled are presented in the GLOBE model; if you do not label any data
ANALOG01–ANALOG64, then no analog value items appear in GLOBE.
You can format the data as 16-bit integers or 32-bit floating point numbers.
Use SEL-2030 math/movement settings to move and format data within the
SEL-2030. For example, if you want to map the A-phase current scaled by 10
(as an integer) on Port 1 to the GLOBE item ANALOG01, enter
0h,i;;ANALOG01=1:METER:IA*10. To format the data as a floating point
value use 0h,f;;ANALOG01:=1:METER:IA*10. See the SEL-2030 Reference
Manual for complete information on the syntax of SEL-2030 math/movement
settings.
Using math/movement settings, you can collect, scale, and manipulate data
from any port database of the SEL-2030. The SEL-2701 automatically maps
data to the GLOBE model. For example, if you have less than 64 items total,
you may want to collect all data to the port (Port 17 or 18) where the
SEL-2701 is installed. If you wish to have data associated with a local virtual
device, then you can program math/movement settings on each port.
Generic Binary Data
The SEL-2701 maps up to 256 binary values to each GLOBE model. The
SEL-2701 maps bits from 16 data words to items within the GLOBE model as
shown in Table 4.8 on page 4.11. The Example Setting column shows an
example math/movement equation that you could use to pack data into
DWORD01 using address 1 of the User region. The remaining bits of
DWORD01 are unused and will remain zero. You must include the label for
the data word in the last math/movement statement that references the data
word where you are packing the binary information (see setting for
DWORD01B08$b1 in Table 4.8).
