Operation manual

In contrast to cyclic communication, acyclic communication data are only 
exchanged when necessary. Acyclic communication is performed either via an 
appropriate routine within cyclic communication (for PKW routine, see 
PROFIDrive profile version 2) or via the DP-V1 routines READ and WRITE. This 
permits the connection of commissioning tools as class-2 master (C2) to 
PROFIBUS. 
Several acyclic channels are available at the same time. The C1 master (the 
controller) maintains a continuously open connection to the inverter (MSAC1) 
which can be used as necessary by the controller program (arrow 2). In addition, 
the inverter provides the capacity for two connections (MSAC2) which can be 
established and used as necessary by C2 masters (e.g., an operator panel or a 
service PC).
Time wise on PROFIBUS, the cyclic data always have the highest priority. During 
each data exchange cycle, the master inserts an acyclic telegram when 
necessary. This does not noticeably affect the speed of PROFIBUS.

5.3.2

User data communication

The process data channel is used for high-speed transmission of data which are 
used for controlling and monitoring the running process and which require a 
particularly short transmission time. When the bus system is configured, the 
selection of the PPO type specifies whether the cyclic parameter channel is to be 
used and how many bytes the process data channel will have.

All parameters can be read and changed with the parameter channels. First, the 
PKW1 routine (which uses the acyclic services of PROFIBUS) specified by 
PROFIDrive version 3 is available and, second, the old PKW0 routine (which is 
embedded in the cyclic data) defined by PROFIDrive version 2 is offered. 
Because of the comprehensive capabilities and the access to all inverter 
parameters without exception, the new PKW1 routine should be used if possible:

Transmission Channel
