6. Acyclic Parameter Access
6.1 What is Acyclic Data?
• Acyclic / non-cyclic / Service access provides a method for the network master to access any drive or
module parameter.
• This kind of parameter access is typically used for monitoring or low priority non-scheduled parameter
access.
• The PositionServo PROFIBUS-DP module supports several different methods of doing this.
6.2 Setting the Acyclic Mode
6.2.1 Acyclic Modes
The Acyclic mode can be set in the MVOB [Communications] [PROFIBUS DP] folder by clicking on the down
arrow [t] next to [PROFIBUS DP Acyclic Mode] and selecting the mode from the pull-down menu.
Or PID310 can be used to select the required Acyclic mode. Refer to section 6.3 for details on type of
acyclic mode. The acronym "8BAD" indicates "8 Byte Acyclic Data".
