7.106 Data Element: DE_PreemptState
Use: The PreemptState data element is used to relate the current preemption state of a signal system.
Note that this data element follows the values and definitions of the preemptState object of NTCIP 1202
v2.19f as its starting point and adds values of 0 and 10.
ASN.1 Representation:
PreemptState ::= ENUMERATED {
none (0), -- No preemption (same as value = 2)
other (1), -- Other
notActive (2), -- Not Active (same as value = 0)
notActiveWithCall (3), -- Not Active With Call
entryStarted (4), -- Entry Started
trackService (5), -- Track Service
dwell (6), -- Dwell
linkActive (7), -- Link Active
existStarted (8), -- Exit Started
maximumPresence (9), -- Max Presence
activeButOverridden (10), -- Active but Over-ridden
... -- # LOCAL_CONTENT
}
-- To use 4 bits,
-- typically packed with other items in a BYTE
XML Representation:
