Link Adapter A Unit used to connect communications lines, either to branch the lines or to
convert between different types of cable. There are two types of Link
Adapter: Branching Link Adapters and Converting Link Adapters.
link A hardware or software connection formed between two Units. “Link” can
refer either to a part of the physical connection between two Units (e.g., opti-
cal links in Wired Remote I/O Systems) or a software connection created to
data existing at another location (Network Data Links).
linkable slot A slot on either a CPU or Expansion I/O Backplane to which a Link Unit can
be mounted. Backplanes differ in the slots to which Link Units can be
mounted.
Link System A system that includes one or more of the following systems: Remote I/O
System, PC Link System, Host Link System, or Net Link System.
Link Unit Any of the Units used to connect a PC to a Link System. These are Remote
I/O Units, I/O Link Units, PC Link Units, Host Link Units, and Net Link Units.
load The processes of copying data either from an external device or from a stor-
age area to an active portion of the system such as a display buffer. Also, an
output device connected to the PC is called a load.
local area network A network consisting of nodes or positions in a loop arrangement. Each node
can be any one of a number of devices, which can transfer data to and from
each other.
logic block A group of instructions that is logically related in a ladder-diagram program
and that requires logic block instructions to relate it to other instructions or
logic blocks.
logic block instruction An instruction used to locally combine the execution condition resulting from
a logic block with a current execution condition. The current execution condi-
tion could be the result of a single condition, or of another logic block. AND
Load and OR Load are the two logic block instructions.
logic instruction Instructions used to logically combine the content of two words and output
the logical results to a specified result word. The logic instructions combine
all the same-numbered bits in the two words and output the result to the bit of
the same number in the specified result word.
loop A group of instructions that can be executed more than once in succession
(i.e., repeated) depending on an execution condition or bit status.
LR area A data area that is used in a PC Link System so that data can be transferred
between two or more PCs. If a PC Link System is not used, the LR area is
available for use as work bits.
LSS Abbreviation for Ladder Support Software.
main program All of a program except for the subroutines.
masking ‘Covering’ an interrupt signal so that the interrupt is not effective until the
mask is removed.
