SET M - MATH/DATA MOVEMENT SETTINGS
You use the SET M n command to create a macro that automatically copies specific data from
any designated SEL-2020 port database to the SEL-2020 port “n” database User region. This
permits you to concentrate selected data from one or more port databases into a single port
database User region for quick and easy data retrieval. You can also scale each selected data
item by multiplying or dividing by a scaling constant. The SET M n command permits you to
create up to 250 lines of equations and operations for each of the sixteen SEL-2020 port
databases.
This settings class is unique from all others. There are no settings labels and prompts. Instead,
you enter equations and operations as lines within the settings. Because of this, the edit control
keys and commands are slightly different. Table 6.16 lists the available editing keys and
commands.
