Abbreviation

Acyclic communication

Acyclic communication, as opposed to cyclic communication, means data is transferred 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

The STARTER commissioning tool use this protocol, for example, in the online mode via

● PROFIdrive parameter channel with the following data records:

– PROFIBUS: Data block 47 (0x002F)

– PROFINET: Data block 47 and 0xB02F as global access, data block 0xB02E as local

Please refer to the following documentation for a detailed description of acyclic

communication:

Reference: PROFIdrive Profile V4.1, May 2006, Order No: 3.172

• PROFIBUS DP, addressing is carried out via the logical address or the diagnostics

• PROFINET IO, addressing is carried out exclusively via a diagnostics address that is

assigned to a module starting from slot 1. Parameters cannot be accessed using slot 0.
