A peripheral device used to input a program into a PC or to alter or monitor a
program already held in the PC. There are dedicated programming devices,
such as Programming Consoles, and there are non-dedicated devices, such
as a host computer.
A mode of operation that allows inputting and debugging of programs to be
carried out, but that does not permit normal execution of the program.
A peripheral device used to write programs and other data into a ROM for
permanent storage and application.
A message or symbol that appears on a display to request input from the op-
erator.
Acronym for present value.
An assembly of various Units on a Backplane that forms a functional unit in a
building-block PC System. Racks include CPU Racks, Expansion I/O Racks,
I/O Racks, and Slave Racks.
The process of updating output status sent to external devices so that it
agrees with the status of output bits held in memory and of updating input
bits in memory so that they agree with the status of inputs from external de-
vices.
The forerunner of PCs. In relay-based control, groups of relays are intercon-
nected to form control circuits. In a PC, these are replaced by programmable
circuits.
The Unit in a Remote I/O System through which signals are sent to all other
Remote I/O Units. The Remote I/O Master Unit is mounted either to a CPU
Rack or an Expansion I/O Rack connected to the CPU Rack. Remote I/O
Master Unit is generally abbreviated to Master.
A Unit mounted to a Backplane to form a Slave Rack. Remote I/O Slave Unit
is generally abbreviated to Slave. The operation of a Slave is controlled by a
Master.
A system in which remote I/O points are controlled through a Master
mounted to a CPU Rack or an Expansion I/O Rack connected to the CPU
Rack.
Any of the Units in a Remote I/O System. Remote I/O Units include Masters,
Slaves, Optical I/O Units, I/O Link Units, and Remote Terminals.
An I/O word allocated to a Unit in a Remote I/O System.
The process of turning a bit or signal OFF or of changing the present value of
a timer or counter to its set value or to zero.
The process whereby a device will re-transmit data which has resulted in an
error message from the receiving device.
The process by which instruction execution shifts from a subroutine back to
the main program (usually the point from which the subroutine was called).
