Data and Control Block -- Digital I/O Pulse Output Card Overlay (Note 15) 15) read-only except as
indicated
2B3F - 2B3F 11072 - 11072 Digital Input States UINT16 bit-mapped dddd cccc bbbb aaaa Nibble "dddd" for
input#4, "cccc" for
input#3, "bbbb" for
input#2 and "aaaa" for
input#1.
Within each field,
rightmost bit is the
current state (1=closed,
0=open), and bits at
left are the older states
100ms apart (historical
states).
Example:
xxxx xxxx xxxx 0011
Current state of input#1
is closed, before that it
was closed too, before
that it was open and
the oldest state known
is open.
