PROFIdrive V3: Acyclic parameter accessing with data block 47
Acyclic parameter accessing with data block 47 is supported by the
CBP2 with firmware version V2.23 and later.
A detailed description of acyclic parameter accessing with data block 47
can be found in PROFIBUS Profile, PROFIdrive (PNO: Order No. 3172).
♦
Compatibility with PKW tasks in accordance with PROFIdrive profile
version 2
♦
16-bit wide address for each parameter number and subindex
♦
Transfer of complete arrays or areas thereof, or the entire parameter
description
♦
Transfer of different parameters in one access operation (multi-
parameter tasks)
♦
Only
one
parameter task is processed at a time (no pipelining)
♦
A parameter task/response must fit into one data block (max. 240
bytes). Tasks/responses are
not split
over several data blocks. The
maximum length of data blocks can be less than 240 bytes as a result
of slave property or bus configuration.
♦
"Multi-parameter"
tasks are defined for optimized, simultaneous
access to different parameters (e.g. HMI screen contents).
♦
Data block 47 can be processed by acyclical channels MSAC_C1 and
MSAC_C2.
The definition of an array has been changed in IEC 61158 as compared
to the definition in EN 50170.
The PROFIdrive profile version 2 is compliant with EN 50 170, according
to which the subindex of an indexed parameter or array begins with index
1. In the current IEC standard 61158, access to an indexed parameter or
array begins with the index 0.
As a consequence, the parameter model and the DPV1 parameter
channel had to be adapted in PROFIdrive profile version 3 so as to
ensure compliance with the IEC standard.
MASTERDRIVES continues to use the parameter model according to
PROFIdrive V2 at the internal interface. MASTERDRIVES can be
accessed via data block 47 as a DPV1 client with the CBP2. For tasks
using DB47, the CBP2 thus adds an offset of 1 to the parameter
subindex.
The cyclical parameter access via PKW and the acyclical parameter
access with data block 100 can continue to be used without any
changes.
