Description of scope
A PKW interface (parameter ID value) can be used between SIMADYN D
and SIMOREG or SIMOVERT drive converters using the communications
utility, parameter processing for variable-speed drives. Drive converter-
and technology parameters can be read and changed via the PKW
interface.
Process data are transferred and parameters handled for the coupling
between the drive converters and SIMADYN D. On the SIMADYN D side,
process data is transferred using the transmit- and receive function
blocks (CTV/CRV).
@DPH and DPI function blocks, are used for parameter handling. They
are used to read and change drive converter- and technology
parameters, and they can also receive parameter change reports from
the drive converters. The function blocks for parameter handling
(in the following known as PKW blocks) can be used independently of the
existing SIMADYN D couplings. However, it is necessary to refer to the
correct protocol by appropriately configuring.
The PKW blocks do not have a direct connection at a data interface of a
coupling module. Data transfer is always realized using transmit- and
receive blocks (CTV, CRV).
The PKW interface is sub-divided into two block types:
1.
Blocks to supply transmit- and receive blocks.
These blocks have the main task to convert the parameter tasks and
responses into a format corresponding to the definition (parameter ID,
index and parameter value as well as parameter change report), and
to transfer these to the transmit blocks, or receive them from the
receive blocks. Further, the received parameter change reports are
output at this block type. This block type is designated as PKW central
block @DPH in the following ( Device Parameter Handling).
2.
Blocks for the man-machine interface (MMI).
The tasks are specified here in a comprehensible form and the
device/drive converter responses displayed. This is configured. By
cascading this block type, an automatic task sequence can be
configured. This block type is known in the following as parameter
block DPI (Device Parameter Information.
The interconnection and the information transfer between both block
types is not visible and cannot be influenced by the user/configuring
engineer.
