Glossary
such as Programming Consoles, and there are non-dedicated devices, such as
a host computer.
Discrete signals sent at a certain rate. The Motion Control Unit outputs pulses,
each of which designates a certain amount of movement. Such pulses are con-
verted to an equivalent control voltage in actual positioning.
The distance moved the motor shaft divided by the number of pulses required for
that movement.
A series of pulses output together.
In network communications, the node or device with which communications are
taking place. See local.
The processes of copying data either from an external device or from a storage
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.
The lowest numbered bits of a group of bits, generally of an entire word, or the
lowest numbered words of a group of words. These bits/words are often called
least-significant bits/words.
The operating mode used by the PC for normal control operations.
The process whereby the PC provides data to or receives data from external
devices or remote I/O Units, or otherwise handles data transactions for Link Sys-
tems.
An operation whereby a rotary encoder is used to maintain the position of a
motor while it is stopped. Whenever the motor axis moves, the rotary encoder
sends a feedback pulse to an error counter, causing a rotation voltage to be gen-
erated in the reverse direction so that the motor rotates back to its original posi-
tion.
An error that originates in a software program.
Abbreviation for SYSMAC Support Software.
A group of instructions that are executed independently of the main program.
A parameter for a positioning action that designates what position is to be
reached at the completion of the action.
Automatically writing the present position into memory, via the Teaching Box, as
the target position for the designated positioning action.
The process of moving data from one location to another within the PC, or
between the PC and external devices. When data is transferred, generally a
copy of the data is sent to the destination, i.e., the content of the source of the
transfer is not changed.
The process of transferring a program or data from a lower-level or slave com-
puter to a higher-level or host computer. If a Programming Devices is involved,
the Programming Device is considered the host computer.
A timer within the system that ensures that the scan time stays within specified
limits. When limits are reached, either warnings are given or PC operation is
stopped depending on the particular limit that is reached.
