Bit(s) or word(s) designated as the data to be used for an instruction. An op-
erand can be input as a constant expressing the actual numeric value to be
used or as an address to express the location in memory of the data to be
used.
A bit designated as an operand for an instruction.
A word designated as an operand for an instruction.
An error that occurs during actual PC operation as opposed to an initializa-
tion error, which occurs before actual operations can begin.
A Unit that is connected in an Optical Remote I/O System to provide 8 I/O
points. Optical I/O Units are not mounted to a Rack.
A Slave Rack connected through an Optical Remote I/O Slave Unit.
A logic operation whereby the result is true if either of two premises is true, or
if both are true. In ladder-diagram programming the premises are usually ON/
OFF states of bits or the logical combination of such states called execution
conditions.
The signal sent from the PC to an external device. The term output is often
used abstractly or collectively to refer to outgoing signals.
A bit in the IR area that is allocated to hold the status to be sent to an output
device.
An external device that receives signals from the PC System.
The point at which an output leaves the PC System. Output points corre-
spond physically to terminals or connector pins.
A signal being sent to an external device. Generally an output signal is said
to exist when, for example, a connection point goes from low to high voltage
or from a nonconductive to a conductive state.
Part of the processing performed by the CPU that includes general tasks re-
quired to operate the PC.
Changing the content of a memory location so that the previous content is
lost.
Adjustment of the number of ON bits in a word or other unit of data so that
the total is always an even number or always an odd number. Parity is gener-
ally used to check the accuracy of data after being transmitted by confirming
that the number of ON bits is still even or still odd.
An acronym for Programmable Controller.
An acronym for printed circuit board.
The arrangement and interconnections of the Units that are put together to
form a functional PC.
