Acronym for plastic-clad optical fiber cable.
A system in which PCs are connected through PC Link Units to enable them
to share common data areas, i.e., each of the PCs writes to certain words in
the LR area and receives the data of the words written by all other PC Link
Units connected in series with it.
The Unit used to connect PCs in a PC Link System.
With building-block PCs, all of the Racks and independent Units connected
directly to them up to, but not including the I/O devices. The boundaries of a
PC System are the PC and the program in its CPU at the upper end; and the
I/O Units, Special I/O Units, Optical I/O Units, Remote Terminals, etc., at the
lower end.
Devices connected to a PC System to aid in system operation. Peripheral
devices include printers, programming devices, external storage media, etc.
A connector on a PC or computer that serves as a connection to an external
device.
The current value registered in a device at any instant during its operation.
Present value is abbreviated as PV.
A board onto which electrical circuits are printed for mounting into a comput-
er or electrical device.
A Unit used to interface a printer so that ladder diagrams and other data can
be printed out.
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.
Although single-component Programmable Controllers are available, build-
ing-block Programmable Controllers are constructed from separate compo-
nents. Such building-block Programmable Controllers are formed only when
enough of these separate components are assembled to form a functional
assembly, i.e., no one individual Unit is called a PC.
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 the execution of an instruction designed to gen-
erate 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.
