The most basic type of Unit mounted to a Backplane. I/O Units include Input
Units and Output Units, each of which is available in a range of specifications.
I/O Units do not include Special I/O Units, Link Units, etc.
A error generated by a disagreement between the Units registered in the I/O
table and the Units actually mounted to the PC.
A word in the CIO area that is allocated to a Unit in the PC System and is used to
hold I/O status for that Unit.
A computer that has similar architecture to, that is logically compatible with, and
that can run software designed for an IBM PC/AT computer.
A form of I/O refreshing that is executed by certain types of instruction when the
instruction is executed to ensure that the most current input status is used for an
operand or to ensure that an output is effective immediately.
The status of a step in an SFC program in which the actions within that step are
not executed, with the exception of any actions with action qualifiers that extend
execution beyond active status. Inactive status also enables a step to go into
active status provided other conditions are met.
Increasing a numeric value, usually by 1.
A data storage location used with or without a data register in indirect address-
ing.
A step that automatically goes to active status when SFC program execution is
begun.
Part of the startup process whereby some memory areas are cleared, system
setup is checked, and default values are set.
The signal coming from an external device into the PC. The term input is often
used abstractly or collectively to refer to incoming signals.
A bit in the CIO area that is allocated to hold the status of an input.
A Unit used in combination with a Remote Interface to create an I/O Terminal. An
Input Block provides mounting positions for replaceable relays. Each relay can
be selected according to specific input requirements.
An external device that sends signals into the PC System.
The point at which an input enters the PC System. Input points correspond phys-
ically to terminals or connector pins.
A change in the status of a connection entering the PC. Generally an input signal
is said to exist when, for example, a connection point goes from low to high volt-
age or from a nonconductive to a conductive state.
An I/O Terminal that provides input points.
The process by which a program section held in a peripheral device is saved in
PC memory at the location just prior to the last program section that was saved.
A direction given in the program that tells the PC of the action to be carried out,
and the data to be used in carrying out the action. Instructions can be used to
