Q
An event report is collected and archived to 1:A3 database. The 1:ARCH3 bit is asserted each time
a long event record is received. After the event report is received, the SEL-2020 clears the
1:ARCH3 bit.
R
The SELOGIC Control Equation Processor detects the !1:ARCH3 condition and sets the D2 bit. You
previously defined this issue condition as ISSUE2=!1:ARCH3 using the SET A command for Port 9.
S
The Message Generator detects the D2 bit is set and issues MESG2. This message retrieves data from
Archive Region A3 and sends it to the printer on Port 9, then clears the A3 region. You previously
defined MESG2 as MESG2=\F1:A3;C/ using the SET A command for Port 9.
