A position on a Rack (Backplane) to which a Unit can be mounted.
An error that originates in a software program.
A means of protecting data from being changed that uses software as op-
posed to a physical switch or other hardware setting.
The location from which data is taken for use in an instruction, as opposed to
the location to which the result of an instruction is to be written. The latter is
called the destination.
A dedicated Unit that is designed for a specific purpose. Special I/O Units
include Position Control Units, High-speed Counter Units, Analog I/O Units,
etc.
A data area in a PC used mainly for flags, control bits, and other information
provided about PC operation. The status of only certain SR bits may be con-
trolled by the operator, i.e., most SR bits can only be read.
A group of instructions placed after the main program and executed only if
called from the main program or activated by an interrupt.
A definer used to identify the subroutine that a subroutine call or interrupt
activates.
Abbreviation for set value.
The maximum voltage/current that a relay can safely switch on and off.
An error in the way in which a program is written. Syntax errors can include
‘spelling’ mistakes (i.e., a function code that does not exist), mistakes in
specifying operands within acceptable parameters (e.g., specifying write-
protected SR bits as a destination), and mistakes in actual application of in-
structions (e.g., a call to a subroutine that does not exist).
The arrangement in which Units in a system are connected.
An error generated by the system, as opposed to one resulting from execu-
tion of an instruction designed to generate an error.
An error message generated by the system, as opposed to one resulting
from execution of an instruction designed to generate a message.
A data area that can be used only for timers and counters. Each bit in the TC
area serves as the access point for the SV, PV, and Completion flag for the
timer or counter defined with that bit.
A definer that corresponds to a bit in the TC area and used to define the bit
as either a timer or a counter.
An instruction placed on the right side of a ladder diagram that uses the final
execution conditions of an instruction line.
The code comprising an asterisk and a carriage return (* CR) which indicates
the end of a block of data, whether it is a single-frame or multi-frame block.
Frames within a multi-frame block are separated by delimiters.
