Acyclic communication
11.1.4.1
General information about acyclic communication
With acyclic communication, as opposed to cyclic communication, data transfer takes place
only when an explicit request is made (e.g. in order to read and write parameters).
The "Read data record" and "Write data record" services are available for acyclic
communication.
The following options are available for reading and writing parameters:
● S7 protocol
This protocol uses the STARTER commissioning tool in online operation via
PROFIBUS/PROFINET.
● PROFIdrive parameter channel with the following data sets:
– PROFIBUS: Data block 47 (0x002F)
The DPV1 services are available for master class 1 and class 2.
– PROFINET: Data block 47 and 0xB02F al global access, data set 0xB02E as local
access
Note
Refer to the following documentation for a detailed description
of acyclic
Reference: PROFIdrive Profile V4.1, May 2006, Order No.: 3.172
PROFIBUS DP
The addressing is carried out via the logical address or the diagnostics address.
PROFINET IO
The addressing is only undertaken using a diagnostics address which is assigned
to a module as of slot 1. Parameters cannot be accessed via socket 0.
