The code in which a program is written, e.g., ASCII. Source code must be con-
verted to object code before execution.
A 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.
Static random access memory; a data storage media.
A basic unit of execution in an SFC program. Steps are used to organize an SFC
program by process and control the overall flow of program execution.
A memory area that contains a flag that indicates the status of steps in an SFC
program.
A timer used to time execution of actions within a step in an SFC program.
The process by which a program section held in a peripheral device is saved in
PC memory at the same location from which it was read.
A sequence of letters, numbers, and/or symbols stored in memory.
A section of an SFC program that is executed like a subroutine. See subroutine .
A step in an SFC program that is used to call (activate) a subchart.
A step in SFC programming that begins a subchart.
A triangular symbol in SFC programming that comes before the entry step in a
subchart.
A step in SFC programming that ends a subchart.
A triangular symbol in SFC programming that comes after the return step in sub-
chart.
A line mode used in a Remote I/O System to maintain communications when an
error occurs on the positive line.
A group of instructions placed separate from the main program and executed
only when called from the main program or activated by an interrupt.
A definer used to identify the subroutine that a subroutine call or interrupt acti-
vates.
Abbreviation for set value.
Execution of programs and servicing operations in which program execution
and servicing are synchronized so that all servicing operations are executed
each time the programs are executed.
The form of a program statement (as opposed to its meaning). For example, the
two statements, LET A=B+B and LET A=B*2 use different syntaxes, but have
the same meaning.
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 specify-
ing operands within acceptable parameters (e.g., specifying read-only bits as a
