Rectifier/Regenerating Unit Operating Instructions
The parameter value PWE is always transferred as double word (32-bit value) PWE1 and PWE2. The high-
order word is entered as PWE1 and the low-order word as PWE2. In the case of 16-bit values, PWE1 must be
set to 0 by the master.
Example
Read parameter P140.004 (for details, see Section 4.5.6, "Structure of request/response telegrams“):
Request identifier PKE = 0x608C (request parameter value (array) P101),
Index IND = 0004h = 4d
Parameter value PWE1 = PWE2 = 0
SIMOVERT response:
Response identifier PKE = 0x408C,
Index IND = 0004h = 4d
Value of P140.004 = 1388h = 5000d,
i.e. 5.000Ω (PWE1 = 0, because it is not a double word parameter)
Rules for job/response processing:
A job or a response can only ever refer to one parameter.
The master must send the job repeatedly until it receives an appropriate response from the slave. The
master recognizes the response to the job it has sent by analysing the response identifier, the parameter
number, the parameter index and the parameter value.
The complete job must be sent in one telegram. The same applies to the response.
The actual values in repeats of response telegrams are always up-to-date values.
If no information needs to be fetched via the PKW interface (but only PZD) in cyclic operation, then a "No
job" job must be issued.
PROFIBUS devices have a variety of difference performance features. In order to ensure that all master
systems can correctly address each supplementary board, the characteristic features of each board are stored
in a separate device master file (GSD).
File <siem8045.gsd> is needed for board CBP2.
The appropriate file can be chosen in the selection menu for the SIMOVERT MASTER DRIVES
files in later
versions of the configuring tool.
If a device master file is not available in the menu, it can be collected from an Internet site. The Internet address
is http://www.ad.siemens.de/csi/gsd or http://www.ad.siemens.de/simatic-cs

The communication boards can only be operated on a non-Siemens master as a DP standard slave, the
corresponding GSD file containing all necessary information for this mode.
Detailed information about communication via PROFIBUS can be found in Section 8.2 of the compendium for
SIMOVERT MASTER DRIVES Motion Control (order no. 6SE7080-0QX50).
4.5.2.2 Diagnostic tools:
LED displays of CBP2 (flashing LEDs mean normal operation):
Red LED Status of CBP2
Yellow LED Communication between SIMOVERT and CBP2
Green LED Communication between CBP2 and PROFIBUS
