Glossary of Terms GEH-6405 Toolbox for an AVDV Series Drive
realtime
Immediate response. It refers to process control and embedded systems, and fast
transaction processing systems that must respond instantly to changing conditions.
reboot
To restart the toolbox.
relay ladder diagram (RLD)
A ladder diagram has a symbolic power source. Power is considered to flow from the
left rail through a contact to the coil connected to the right.
RS-232C
An EIA Recommended Standard (RS) for the serial link communications interface
for interconnecting data terminal equipment, such as printers, computer monitors, or
computers to data communications equipment, such as modems, for transmission
over a telephone line or network. RS-232C uses an unbalanced or single-ended
voltage interface. (Also see EIA.)
RS-485
An EIA standard for multipoint communications. RS-485 is similar to RS-422 but
can support more nodes per line because it uses lower-impedance drivers and
receivers.
sample set
Set of values taken when signals are being trended together with the Trend Recorder.
sampling rate
The period that values are collected to put in a sample set.
self-tune
Self-tune is a process where the drive and the motor perform predefined tests to
determine the best running conditions for the system.
signal
The basic unit for variable information. Signals are the placeholders for memory
locations in the toolbox’s different platforms.
TCP/IP
Communications protocols developed to inter-network dissimilar systems. It is a de
facto UNIX standard, but is supported on almost all systems. TCP controls data
transfer and IP provides the routing for functions, such as file transfer and e-mail.
toolbox
A Windows-based software package used to configure drives.
trend
A time-based plot to show the history of values.
