4.5.6 Acyclic data via PROFIBUS-DP
4.5.6.1 Introduction
Acyclic communications with a slave via PROFIBUS-DP can basically be
established by a Class 1 master and a Class 2 master simultaneously. This
means that the variable frequency drive/variable speed starter will need to
handle acyclic requests and responses from/to both masters.
4.5.6.2 Addressing
The parameter channel is embedded as a payload data block in the acyclic
PROFIBUS write/read PDUs.
The acyclic data objects of a slave are addressed via slots and indexes on the
PROFIBUS. SWD maps the slot to the SWD module address. The parameter
channel is always addressed with index 47.
4.5.6.3 Protocol
Acyclic services (index-based addressing and payload data) are mapped the
same way on SWD by the PROFIBUS-DP gateway (EU5C-SWD-DP). As a
result, the parameter channel can be used in a fully transparent manner by
SmartWire-DT modules.
The following diagram illustrates the protocol between the PROFIBUS-DP
master, PROFIBUS-DP gateway, and a variable frequency drive/variable
speed starter.
