BUS System
BUS Systems are used as a communication medium
for sectored actuators, sensors and steering in the
automation industry and where electronic modules
have to be connected easily. Only one cable
connects all components.
Field bus is the generic name for all bus systems which are used for the metrology, steering and controlling
engineering.
These are:
• CAN
• ProfiBUS
• InterBUS
• ASI BUS
According to DIN (German Institute for
Standardization) standard a field bus in general
should transmit a small volume of data in fast time
series on a digital compare between sensors,
actuators and steering. as the requirements to the bus
system depends on the level of automation, there is no field bus which can solve all tasks optimal
together.
Following table shows a short overview of the most
important features of the three most popular
