Terminating Resistor
Terminating resistor at the start and end of a bus cable. Prevents
interference due to signal reflection and is used for the adaptation of
bus cables. Bus terminating resistors must always be the last unit at
the end of a bus segment.
Acknowledge
Acknowledgement returned by the receiving station after having
received a signal.
Address
Number that identifies a memory area, systems or module within a
network, for example.
Addressing
Assignment or setting of an address for a module in the network, for
example.
Active metallic component
Conductor or conductive component that is live when in operation.
Analogue
Value, such as voltage, that is infinitely variable and proportional.
Analogue signals can acquire any value within specific limits.
Automation product
I/O controlling device that is interconnected to a system process.
Programmable controllerss represent a special group of automation
products.
Baud
Unit for the data transfer rate. One baud is equivalent to the
transmission of one bit per second (bps).
Baud rate
Unit of measure of the data transmission speed in bit/s.
