Profibus (Process Field Bus) is an established protocol in automation technology. The standardized bus system acc. to IEC 61156 is mainly use for large transmission distances with rather low transmission rates.
There are 3 types of Profibus cables:
| Profibus DP (decentralised periphery) | the most commonly used variant is for controlling sensors and actuators via a central controller in production technology |
| Profibus PA (Process Automation) | is used in process and process engineering |
| Profibus FMS (Fieldbus Message Specification) | is no longer part of the international fieldbus standard |
