Digital Input Control
CONTROL OUTPUTS
Multiple Output Controller
The
multiple output controller provides digital
outputs in groups of 16, display outputs in groups
of four, and analog outputs in groups of two (8-bit)
or one (10-bit). Any combination up to 64 groups
of the above functions can be handled by one output
controller. Relay outputs may be either latched or
momentary contacts.
The output relay's operating time is approxi-
·mate
ly
2. 4 milliseconds, but the controller
'
s logic
allows 3. 5 .milliseconds for one operation plus 0.
5
milliseconds for
timer
recovery. Thus,
2
50
multiple output operations per second are possible,
or 4000 digital points per second.
Operating
times are program selectable, either
4 milliseconds and 40 microseconds, or optionally,
4 milliseconds and 75 milliseconds. The 75 milli-
seconds is adjustable by
hardware from 20 to 150
milliseconds.
After receipt of a control word from the arith-
metic unit, the multiple output controller is
entirely independent of the arithmetic
unit
and does
its own timing. With
the
execution of a TOM
function,
the
control word, containing both the group
address and data information, is transferred to the
multiple output register (MOR) from the arithmetic
unit.
A special five-relay matrix is used for
in-line
decimal displays, energized by four bits in the MOC
command word.
