A PC that is constructed from individual components, or “building blocks.” With
building-block PCs, there is no one Unit that is independently identifiable as a
PC. The PC is rather a functional assembly of Units.
A communications path used to pass data between any of the Units connected
to it.
The line leading down the left and sometimes right side of a ladder diagram. In-
struction execution proceeds down the bus bar, which is the starting point for all
instruction lines.
A data link that passed data between two Units across a bus.
A unit of data equivalent to 8 bits, i.e., half a word.
A device that is capable of storing programs and data, and executing the instruc-
tions contained in the programs. In a PC System, the central processing unit ex-
ecutes the program, processes I/O signals, communicates with external de-
vices, etc.
See word .
A numeric (usually binary) code used to represent an alphanumeric character.
A sum transmitted with a data pack in communications. The checksum can be
recalculated from the received data to confirm that the data in the transmission
has not been corrupted.
A memory area used to control I/O and to store and manipulate data. CIO Area
addresses do not require prefixes.
A table of settings in a SYSMAC LINK System that specifies what words are to
be used in the data links for all PCs in the SYSMAC LINK System. See refresh
parameter table .
Data that is stored in a memory of a PC and which is shared by other PCs in the
same the same system. Each PC has a specified section(s) of the area allocated
to it. Each PC writes to the section(s) allocated to it and reads the sections allo-
cated to the other PCs with which it shares the common data.
A flag used with a timer or counter that turns ON when the timer has timed out or
the counter has reached its set value.
A symbol placed on an instruction line to indicate an instruction that controls the
execution condition for the terminal instruction. Each condition is assigned a bit
in memory that determines its status. The status of the bit assigned to each con-
dition determines the next execution condition. Conditions correspond to LOAD,
LOAD NOT, AND, AND NOT, OR, or OR NOT instructions.
A branch in an SFC program where one step is connected to multiple steps but
the active status can be transferred to only one step at a time.
In an SFC program, a location where multiple steps coming from the same con-
ditional branch return to a single step.
An input for an operand in which the actual numeric value is specified. Constants
can be input for certain operands in place of memory area addresses. Some op-
erands must be input as constants.
