CDS_SWITCH equal to 1 on the string means the string is supposed to use all mnemonic limits defined with Switch Mnemonic "CDS_SWITCH" and a range that includes 1. In general: A LIMIT DEFINITION IS IN EFFECT IF AND ONLY IF THE STRING'S VALUE FOR THE SWITCH MNEMONIC IS WITHIN THE SWITCH MNEMONIC RANGE.
LIMIT_SWITCH with a range of 1 to 1 means nominal limits for the team.
LIMIT_SWITCH with a range of 2 to 2 is never used - these limtis were defined early in the mission and aren't used because it is an all-or-nothing thing. Instead, the [INSTRUMENT]_SWITCH was created.
[INSTRUMENT]_SWITCH with a range of 1 to 1 are nominal limits for that instrument.
[INSTRUMENT]_SWITCH with a range of 2 to 2 are ESR limits. If we go into ESR, the FOT switch to ESR limits for CDS, LASCO, UVCS (only if they are on the ESR warning flag receipt list) in the ESR Initial Operations Script CS-06B. SWAN will soon have ESR limits as well.
[INSTRUMENT]_SWITCH with a range of 3 to 3 are door closed limits.
------------Switch----Switch Mnem.
Mnemonic---Mnemonic---Range Lo/Hi---Limits
IIVMCPPP---INS_SWITCH ----1/1-------[IIVMCP nominal limits]
IIVMCP-----INS_SWITCH-----2/2-------[IIVMCP ESR limits]

IXMP-------LIMIT_SWITCH---1/1-------[IXMP nominal limits]
IXMP-------LIMIT_SWITCH---2/2-------[IXMP never used limits]
IISSMP-----IXSTAT---------0/100-----[IISSMP limits for 0 < IXSTAT < 100]
IISSMP-----IXSTAT---------101/255---[IISSMP limits for 101 < IXSTAT < 255]
IIVMCP---INS_SWITCH-----1/1-----[IIVMCP nominal limits]
IIP------INS_SWITCH-----1/1-----[IIP nominal limits]
IXMP-----LIMIT_SWITCH---1/1-----[IXMP nominal limits]
IISSMP---IXSTAT---------0/100---[IISSMP limits for 0 < IXSTAT < 100]
IIVMCP---INS_SWITCH-----3/3-----[IIVMCP Door Closed limits]
NOTE: that IIP has no limits defined for any other values of INS_SWITCH than 1, which is perfectly ok as long as the instrument team is aware that the mnemonic is not monitored at all if a non-nominal limit set is applied
IIVMCP---INS_SWITCH-----3/3-------[IIVMCP Door Closed limits]
IXMP-----LIMIT_SWITCH---1/1-------[IXMP nominal limits]
IISSMP---IXSTAT---------101/255---[IISSMP limits for 101 < IXSTAT < 255]
NOTE:The last two limit sets can both be referred to as "Door Closed limit sets". Note also that "Door Closed limit sets" do include limit definitions that are "nominal", when the limit sets are defined this way.
