Glossary
A bit that is programmed to turn ON and OFF at a specific frequency.
A decimal number expressed as a number between 0 and 1 (the mantissa)
multiplied by a power of 10, e.g., 0.538 x 10
A Unit used to interface a floppy disk drive to a PC so that programs and/or
data can be stored on floppy disks.
A memory area located in a File Memory Unit used to store or backup pro-
grams and/or data.
The process of forcibly turning OFF a bit via a programming device. Bits are
usually turned OFF as a result of program execution.
The process of forcibly turning ON a bit via a programming device. Bits are
usually turned ON as a result of program execution.
A two-digit number used to input an instruction into the PC.
Acronym for Graphic Programming Console.
A programming device with advanced programming and debugging capabili-
ties to facilitate PC operation. A Graphic Programming Console is provided
with a large display onto which ladder-diagram programs can be written di-
rectly in ladder-diagram symbols for input into the PC without conversion to
mnemonic form.
An error originating in the hardware structure (electronic components) of the
PC, as opposed to a software error, which originates in software (i.e., pro-
grams).
A number system where all numbers are expressed to the base 16. In a PC
all data is ultimately stored in binary form, however, displays and inputs on
Programming Devices are often expressed in hexadecimal to simplify opera-
tion. Each group of four binary bits is numerically equivalent to one hexadeci-
mal digit.
A system with one or more host computers connected to one or more PCs
via Host Link Units so that the host computer can be used to transfer data to
and from the PC(s). Host Link Systems enable centralized management and
control of PC Systems.
An interface used to connect a PC to a host computer in a Host Link System.
A computer that is used to transfer data or programs to from a PC in a Host
Link System. The host computer is used for data management and overall
system control. Host computers are generally personal or business comput-
ers.
A data area used to store and manipulate data, and to preserve data when
power to the PC is turned OFF.
Increasing a numeric value.
An address whose contents indicates another address. The contents of the
second address will be used as the operand. Indirect addressing is possible
in the DM area only .
