corresponding to the PPO type, and transfers it, using the virtual
communication connections, to the associated transmit block.
After the task has been transferred, the central PKW block starts a
monitoring counter. The response must be received by the central PKW
block within this TIMEOUT, otherwise it is considered as ended by the
central PKW block (with the appropriate information to the parameter
block).
Drive converters can handle PKW interfaces, 3- or 4-words long,
depending on the drive converter. The PKW interface on the SIMADYN D
side can handle both of these formats. The length definition is realized
using initialization inputs PHL at the central PKW block @DPH and
cannot be changed during operation.
In order to handle the PKW interface, the PKW component in the
telegram must be processed. To realize this, the @DPH central block of
the communications utility, parameter processing from variable-speed
drives, inputs (XW1, XW2, XWS and XWL) and output (YW1, YW2, YWS
and YWL) which must be connected to the standard transmit /receive
blocks CTV, CRV via virtual connections (refer to the Chapter
Communications utility, process data).

CS7 module with SS52 communications module
•
A SIMOVERT drive converter is connected to the SS52
communications module via PROFIBUS DP.
The SIMOVERT drive converter is to be operated using the
communications utility, parameter processing, from variable speed drives,
whereby two parameter blocks are to be configured.
The @CSPRO central coupling block is first required when using the
CS7/SS52. In addition, block CRV and block CTV are configured, which
handle data transfer from and to the drive converter. Blocks CRV and
CTV are connected to the @DPH central block via virtual connections.
