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 a signal(s) from the PC System.
The point at which an output leaves the PC System. An output point physical-
ly corresponds to terminals or connector pin(s).
A change in the status of a connection leaving the PC. 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.
An acronym for Programmable Controller.
All of the Units connected to the CPU Unit up to, but not including the I/O de-
vices. The limits of the PC System on the upper end is the PC and the pro-
gram in its CPU and on the lower end, I/O Units, an I/O Link Unit, etc.
An acronym for printed circuit board.
Devices connected to a PC System to aid in system operation. Peripheral
devices include printers, programming devices, external storage media, etc.
The current time left on a timer or the current count of a counter. Present val-
ue is abbreviated PV.
A board onto which electrical circuits are printed for mounting into a comput-
er or electrical device.
The list of instructions that tells the PC the sequence of control actions to be
carried out.
A computerized device that can accept inputs from external devices and gen-
erate outputs to external devices according to a program held in memory.
Programmable Controllers are used to automate control of external devices.
An alarm given as a result of execution of an instruction designed to gener-
ate the alarm in the program as opposed to one generated by the system.
An error arising as a result of execution of an instruction designed to gener-
ate the error in the program as opposed to one generated by the system.
A message generated as a result of execution of an instruction designed to
generate the message in the program as opposed to one generated by the
system.
The simplest form or Programming Device available for a PC. Programming
Consoles are available both as hand-held models and as CPU-mounting
models.
