SEL-2020 Instruction Manual
5. Use the SET A 11 command to define a trigger condition (CMD1 is asserted) and a message
the SEL-2020 sends to the RTU on Port 11. The message (MESG1) is a string you build that
extracts current and voltage meter data from Ports 1 through 7.
Your screen should look similar to the following:
*>>SET A 11<ENTER>
SET A 11<ENTER>SET A 11<ENTER>

Notes:  Enter 1 because you want to define one message trigger and one message.
Set ISSUE1=CMD1 to trigger MESG1 when the SEL-2020 CMD1 element asserts.
! Set MESG1 as shown in the above screen to retrieve the A-phase current and voltage
data stored in the database on each of the SEL relay ports, 1 through 7. Data are defined
with a string format of \Rf;(Port number):(Data region label):(Data item label)/, where
\Rf:...../ requests the data in floating-point format.
