CAN
Controller Area Network, also known as
CAN-bus, is a standardised bus that
enables the devices to communicate
with each other.
CANopen CAN communication protocol.
Protocol specification for devices used in
automation systems.
Work cycle
Fraction of time that represents the active
state of a device, circuit, etc. in relation to
the total time considered.
Data logger
Enables the storage of information for filing
records or further processing.
Duration of
Time required for the output value to reach
settlement
and remain above 90 % of the final value.
Encoder
Rotative position transducer.
Electric Sensor that transforms small dimensional
resistance
deformations of a body subject to
extensometer
mechanical or thermal stress in changes
of electric.
Ethernet
Standard for local networks (LAN).
FLASH
Non-volatile memory in the solid state.
FRAM Non-volatile RAM faster than the Flash
memory.
FTP
File Transfer Protocol.
Allows the upload and download of data
files between the controller and other
digital devices.
LSB
Least Significant Bit.
It defines the minimum resolution of a
measurement.
LSS
Layer Setting Services.
Modbus
Open serial communication protocol, de
facto standard in communication between
industrial electronic devices.
Modbus RTU is the most common
implementation of this standard, Modbus
TCP/IP is that specific m for Ethernet
networks.
Opto isolated Circuit configuration which, through an
electronic component called an opto-
isolator, allows the transferral of a signal
between two circuits while maintaining
galvanic separation.
PID
Regulation algorithm.
PLC Programmable Logic Controller.
A digital computer specialised in the
management of industrial processes.
PWM
Pulse-Width Modulation.
Technique for controlling power towards
electric devices.

RAM
Random Access Memory
Electronic memorising device which
enables the reading and writing of data.
RS-232 Standard which defines a low-speed serial
transmission interface for the exchange of
data between digital
devices, such as modems.
RS-485
Standard, at physical level, for serial
connection with 2 wires.
SD Card Card for memorising large amounts of
digital data.
SDRAM
Synchronised access RAM.
Strain gauge See Electric resistance extensometer.
USB
Universal Serial Bus, serial communication
and feeding standard created to connect
peripherals to computers.
