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.
- 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 BUS systems:
|BUS systems||Highest BPSe||Largest Dimensions||Maximal number
|CAN BUS||1 Mbit/s to 40 m||1 km at 50 Kbit/s||64(128)||ISO 11898|
|ProfiBUS||500 Kbit/s to 200 m||1200 m at 93 Kbit/s||256||ISO 19245|
|InterBUS||500 Kbit/ s to 40 m||12,8 km at 400 m Segments||256||ISO 19258|
