Acyclic data transmission
Extended PROFIBUS DP functionality (DPV1)
The PROFIBUS DP extensions DPV1 include the definition of an acyclic data exchange
which can take place in parallel to cyclical data transmissions.
Acyclic data transfer mode allows:
● Large quantities of user data (up to 240 bytes) to be exchanged
● Simultaneous accessing by other PROFIBUS masters (class 2 master, e.g. start-up tool).
