1 Library Overview
This document describes the “screens_G120” block library. The block library
provides you with tested code with clearly defined interfaces. They can be used as
a basis for your task to be implemented.
A key concern of the document is to describe
 all blocks of the block library
 the functionality implemented through these blocks
Furthermore, this documentation shows possible fields of application and helps you
integrate the library into your STEP 7 project using step-by-step instructions.
1.1 User Scenario
The blocks included in the TIA Portal V12 library “screens_G120” enable fast and
easy operation of a SINAMICS G120 drive.

Apart from a function block for the SIMATIC Controller used, the library includes a
number of screens for integration into a SIMATIC operator panel (HMI). With these
screens the user is able to influence a drive using easy-to-use and clearly designed
user interfaces.

1.2 Block diagram
The block diagram of the “screens_G120“ library is shown below.
Figure 1-2: Block diagram
Process data communication
The SINAMICS drive and the SIMATIC controller communicate through the
process data. Process data is transferred cyclically, which means in each bus
cycle. In this process the controller used transmits a control word and a setpoint
value to the SINAMICS drive and receives a status word and several actual values.
Standard frame 352 should be used on the drive side in order to enable maximum
exchange of information between controller and drive.
When using the free frame configuration, make sure that the first six words of the
process data correspond to the structure of standard frame 352.
Note For information on process data communication and structure of the standard
frames, please refer to the documentation of the SINAMICS G120 drive used.
Blocks for controller and operating panel
The function block (FB) and the user interfaces for the operating panel used in the
controller are part of the “screens_G120” library and will be described in detail in

2.2.2 Functionality of FB “PZD_G120_Tel_352“
Function block “PZD_G120_Tel_352“ performs two tasks:
 Establishing the communication between controller and drive
 Processing the received data and preparing data to be sent
Establishing the communication between controller and drive
The process data communication between the SIMATIC S7-1200/1500/300/400
controller and the SINAMICS G120 drive is carried out in the controller with system
functions (SFC). The following system blocks respectively instructions are being
used:
 SFC14 “DPRD_DAT“ for receiving the drive data
 SFC15 “DPWR_DAT“ for sending data to the drive
Note For more information on the communication with DP standard slaves please
refer to the STEP 7 Online help (TIA Portal) V12.
Processing the received data and preparing data to be sent
The data received from the drive is supplied to the function block interface. The
interface or an operator panel receives the data to be sent to the drive and
forwards the data to the drive.

displayed.

Number of the instance data block
The number of the instance data block to be entered ist the number of the data
block that contains the data of the “PZD_G120_Tel_352“ function block.
Offset of the message data
The offset of the message data is the number of bytes, after which, in an instance
or multi-instance data block, the interface data of the “PZD_G120_Tel_352” starts.
If a separate instance data block is used for every call of function block
“PZD_G120_Tel_352“, the offset will be zero.
Multi-instance is an option to reduce the number of required instance data blocks in
case several calls of function block “PZD_G120_Tel_352“ are used. In this case
function block “PZD_G120_Tel_352“ is called in a different function block, the
interface of which includes the entire data of the “PZD_G120_Tel_352“ function
blocks called.
Figure 2-3: Calling the “PZD_G120_Tel_352“ als multi-instance
The above figure shows the calling of function block “PZD_G120_Tel_352“ in a
function block with the name “call_PZD_G120_Tel_352”. In its instance data block,
the “PZD_G120_Tel_352“ block data starts from byte 8. In this case the number “8”
must be entered as the offset of the message data in screen “screen_G120_start“.
Note For more information on multi-instance, please refer to the STEP 7 Online help
(TIA Portal) V12.
Inverter address when using a SIMATIC S7-300/400 controller
With using a SIMATIC S7-300/400 controller, for parameter “address” of the
function block “PZD_G120_Tel_325” enter the start of the I/O address range that
was assigned during the configuration of the Siemens message 352 of the
SINAMICS G 120 drive in STEP 7.
In the example shown in the figure below, the value 256 must be entered as the
inverter address.

of the SINAMICS G120 drive. A distinction must be made between manual and
automatic mode.
Manual mode
In manual mode the individual parameters of the control word can be switched via
the operator panel. During this process, a control word created internally in function
block “PZD_G120_Tel_352“ will be sent to the drive.

Automatic mode
In automatic mode, control word 1 is merely displayed. These are the values that
are applied as input parameters at the interface of function block
“PTD_G120_Tel_352“ as Bool variables. Influencing these values via the operator
panel is not possible in automatic mode.
Figure 2-7: Display of the control word and status word in automatic mode
In both modes, status word 1 is merely displayed and corresponds to the output
parameters in function block “PZD_G120_Tel_352“of the BOOL data type.
CAUTION Switching between manual and automatic mode is done without checking
the operating state of the drive.

2.3.4 Screen “ screen_G120_data”
The screen “screen_G120_data“ shows the following information:
 Display or input of the setpoint speed of the drive
 Current fault and warning message
 Setpoint speed value in [rpm]
 Current actual value in [A]
 Torque actual value in [Nm]
In addition, the motor can be started and pending faults can be acknowledged from
this screen.

Entering the setpoint speed value is possible in manual mode only. In automatic
mode, only the value of the input parameter “speed_setpoint” of function block
“PZD_G120_Tel_352“ is displayed and transmitted to the drive.
Reference parameters for displaying the actual values
The data received by the drive must be calculated using reference values in order
to be able to display the actual values with the corresponding units. These
reference values are provided by the drive in the form of parameter values.
The values of these reference parameters must be provided to the corresponding
input parameters of function block “PZD_G120_Tel_352“.



This chapter includes instructions for integrating the “screens_G120” library into
your STEP 7 project and instructions for using the library blocks.
3.1 Preparation
The following conditions must be met in order to use the “screens_G120” library:
 Error-free configuration of the SIMATIC controller and the SINAMICS G120
drive with the associated communication connection
 Identical input and output addresses of the SINAMICS drive
 Activation of the German and English language in WinCC TIA V12
 Correct name assignment of the HMI connection
Configuration of controller and drive
Fault-free configuration of the SIMATIC Controller with a SINAMICS G120 drive is
the prerequisite for using the “screens_G120” library.
Note The following applications can be taken as examples for creating the required
configuration:
 “Connecting a SINAMICS G120 Drive to an S7300/400 CPU in TIA Portal”
(Entry ID 60140921)
 “SINAMICS G: Speed Control of a G120 (StartDrive) with S7-1200 (TIA
Portal) via PROFINET/PROFIBUS DP with Safety Integrated (via Terminal)
and HMI” (Entry ID 70155469)
Address assignment of the drive
With the use of a SIMATIC S7-300/400 controller the input and output addresses of
the SINAMICS G120 drive must be identical. This setting is made in the hardware
configuration and is illustrated in Figure 2-4.
Language settings in WinCC TIV V12
The screens of the “screens_G120” library are bilingual. Therefore the following
languages must be set as project languages:
 German (Germany)
 English (USA)
After the required selection the languages must be activated in the Runtime
settings.

Name assignment of the HMI connection
As described in chapter 2.2.7, the name of the HMI connection has been assigned
to be “screens_G120_contact” in the tag table.
Figure 3-2: Name assignment of the HMI connection
In case a different name is to be used for the HMI connection, it must be corrected
in the “screens_G120_variables” tag table. Otherwise there will be no correct
translation of the HMI project.
