Application description
This section provides an overview of how to commission a SINAMICS
G120 with a CU230P-2 DP control unit and PROFIBUS.
1
Description
The CU230 is a Control Unit that has been optimized for pumps and fans. It
can be operated with all power units of the PM240 and PM250 series.
Copyright © Siemens AG 2009 All rights reserved
PDF_Commissioning_of_CU230P_2_DP_with Profibus_en_V1.doc
The CU230 Control Units are available in three versions:
•
CU230P HVAC with USS interface via RS485
•
CU230P CAN with CANopen interface
•
CU230P DP with PROFIBUS DP interface

They can be commissioned either using the STARTER commissioning
software or using the optional "Intelligent Operator Panel - IOP“.
Figure 1-2 Intelligent Operator Panel (IOP)
This application describes the commissioning of the CU230P-2 DP with
PROFIBUS DP interface.
It provides general instructions on how to connect the CU230P-2 DP to a
PROFIBUS DP network, and explains how to commission a SINAMICS
G120 with CU230P-2 DP and SIMATIC S7.
It is assumed for the purpose of this application that the motor and inverter
(the power module and the control unit) have been assembled and that the
inverter has undergone the quick commissioning process.
The information required here can be found in the operating instructions for
the SINAMICS G120 and the CU230P-2 DP control units.

Copyright © Siemens AG 2009 All rights reserved
PDF_Commissioning_of_CU230P_2_DP_with Profibus_en_V1.doc
To integrate the inverter into the PROFIBUS DP fieldbus system, a 9-pin
sub-D connector conforming to the PROFIBUS standard can be found on
the underside of the CU230P-2 DP control unit. The terminals in this
connector are short-circuit proof and potential-free.

PROFIBUS DP cable connector and permitted cable lengths
PROFIBUS DP cable connector
For connecting the SINAMICS G120 frequency inverter, we recommend the
following
PROFIBUS DP cable connectors:
•
6GK1 500-0FC00
•
6GK1 500-0EA02
They are equipped with a switch through which the bus terminating resistor
can be connected.
Copyright © Siemens AG 2009 All rights reserved
PDF_Commissioning_of_CU230P_2_DP_with Profibus_en_V1.doc
Permissible cable lengths
The permissible cable lengths depend on the baud rate and the PROFIBUS
cable.
For more information, visit:
(http://www.automation.siemens.com/net/html_76/support/printkatalog.htm)
2.3
General specifications and requirements for fault-free
communication
You can integrate up to 126 stations into a PROFIBUS DP network. These
must be subdivided into segments of up to 32 stations. You must activate
the bus terminating resistor for the first and last stations of each segment.
You can disconnect one or more slaves from the bus (by unplugging the
bus connector) without interrupting the communication for the other
stations. It is important to ensure that a bus terminating resistor is
connected to the "first" and "last" nodes.
Note
Communication with the controller, even when the line voltage is
switched off
You will have to supply the Control Unit with 24 V DC on terminals 31 and
32 if you require communication to take place with the controller when the
line voltage is switched off.

Setting the PROFIBUS DP address
Before the PROFIBUS DP interface is used, the address of the node point
(inverter) must be set.
The following methods are available for setting the PROFIBUS DP address:
•
Using the address switch on the Control Unit
•
Using parameter p0918
Note
Important notes for setting the PROFIBUS address
The address setting on the DIP switch takes priority over the p0918
settings.
Copyright © Siemens AG 2009 All rights reserved
PDF_Commissioning_of_CU230P_2_DP_with Profibus_en_V1.doc
The PROFIBUS DP address can only be set using p0918 when the
address 0 is set on the DIP switches of the Control Unit (factory setting).
When the address switch is set to a value ≠ 0, the setting in p0918 is
ignored.
The valid address range for Siemens controllers is 1 to 125. Addresses 126
and 127 cannot be used with SIMATIC controllers.

A newly set PROFIBUS DP address will only come into effect after
switching off and on again. It is particularly important that any external 24 V
supply is switched off.

PROFIBUS DP parameters
You can fully integrate your inverter with a CU230P-2 DP Control Unit into
a PROFIBUS communication system without the need for any PROFIBUSspecific parameter settings when the following preconditions are met:
•
The PROFIBUS address is set using a DIP switch
•
The communication procedure uses standard telegram 1
If you want to modify the communication settings, the parameters that you
can use to make changes are listed in the table below.

Creating and Configuring Modules
To control the drive, the organisation block OB1 must now be modified and
a variable table added to the project.
Modify organisation block OB1

Add the following entries to OB1 (see Figure 9-1):
Figure 9-1 Text and comments for OB1
Add variable table
Add a variable table using the SIMATIC Manager menu item "Insert -> S7
Block -> 6 Variable Table" (see Figure 9-2).
Figure 9-2 Adding a variable table
In the variable table, add the following entries for flag words MW0, MW2,
MW4 and MW6 (see Figure10-1).

Controlling the drive

ID-No: 35934076
Controlling the drive
Control word 1 (STW1) and the main set-point (HSW) are sent to the drive
via the PROFIBUS interface. Status word 1 (ZSW1) and the main actual
value (HIW) are received from the drive.
The drive is started by sending the typical control word 047E, followed by
047F (edge of bit 0: ON). In order to stop the drive, word 047E should be
sent to the drive (edge of bit 0: OFF). The control word is sent together with
process data word 1 (PZD1) that should be specified in the variable table
VAT_1 (bit memory word MW0, refer to Fig. 10-1).
Status word 1 (ZSW1) is received from the drive (PZD1) and is transferred
into the bit memory word MW4. The MW4 can be taken from variable table
VAT_1 (refer to Fig. 10-1).
Copyright © Siemens AG 2009 All rights reserved
PDF_Commissioning_of_CU230P_2_DP_with Profibus_en_V1.doc
The main setpoint is sent, together with PZD2 to the drive - and the main
actual value is received from the drive in PZD2. The main set-point should
be specified in the variable table VAT_1 (bit memory word MW2, refer to
Fig. 10-1). The response - the main actual value - is saved in the MW6 and
can be taken from the variable table (refer to Fig. 10-1).
The frequency setpoint and actual value are normalized so that 4000(hex)
corresponds to 50Hz. The highest value that should be sent is 7FFF. The
normalization frequency (reference frequency) can be modified in P2000
(default, 50Hz).
