Glossary
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 reserved
SR bits as a destination), and mistakes in actual application of instructions
(e.g., a call to a subroutine that does not exist).
An optical LAN formed from PCs and other devices connected through SYS-
MAC NET Link Units, NSBs, and NSUs. A SYSMAC NET Link System also
normally contains nodes interfacing computers and other peripheral devices.
PCs in the SYSMAC NET Link System can pass data back and forth, receive
commands from any interfaced computer, and share any interfaced periph-
eral device.
The Unit used to connect PCs to a SYSMAC NET Link System.
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.
A location in memory accessed through a TC bit and used to time down from
the timer's set value. Timers are turned ON and reset according to their ex-
ecution conditions.
A memory area used to store the results of a trace.
The distance that a signal can be transmitted.
A data area used to store execution conditions so that they can be reloaded
later for use with other instructions.
An operation whereby the program is executed and the resulting data is
stored in TM memory to enable step-by-step analysis and debugging.
