Configuration tool for Profibus-DP 1 Characteristics of the Multiturn Encoder on the Profibus
PNO-Ident-Number
The Sendix Absolute Singleturn/Multiturn Encoder has a registered PNO-Ident-Number 5868 (Hex) at the PNO (Profibus User Organization) as an unique identification. The according GSD-Files are named as follows:
• Multiturn Series 5868,5888
• Singleturn Series 5858,5878
KUEB5868.GSD KUEB5868_ST.GSD
Start phase of the encoder on the PROFIBUS
The encoder starts up within the ‘Baud-Search’ state. Once the baud rate has been recognized, it switches to the WAIT_PRM state and waits for the parameter data from the DP-Master. The
parameterisation occurs automatically when the DP-Master starts up. The following parameters are transmitted to the encoder: count direction and the measuring length in steps (for more details, see the Encoder Profile from the PNO). When the correct parameter data have been successfully transferred, the encoder switches to the WAIT_CFG state. The PROFIBUS Master then sends a configuration byte to determine the number of inputs/outputs. If the configuration byte is correct, the encoder switches to the state DATA_EXCHANGE.
Configuration and Parameterisation
The parameterisation, i.e. the transfer of the parameters for count direction, encoder resolution etc., normally occurs within the configuration programme for the PROFIBUS Master used. To do this, the type file or GSD (device file) should be copied to the respective directory for type or GSD files. With some programmes such as COM PROFIBUS or STEP7 Manager, an update of the internal device list (hardware catalogue) must be carried out within the software. For more information about integrating field devices, please refer to the documentation for the software you are using. The two steps described below are normally necessary for integrating and parameterising the encoder in a Master system.
Configuration
For configuration purposes, i.e. to input the length and type of the I/O on the PROFIBUS, the
configuration programme normally provides an input mask (screen), in which – independently of the desired configuration – the identifier has normally already been set as a default, so that only the I/O addresses remain to be entered. Depending on the required configuration that is desired, the encoder allocates a varying number of input and output words on the PROFIBUS.
The following parameters described are also dependent on the required configuration. The GSD device file (e.g. KUEB5868.GSD) contains five required configurations for PNO Class1 and 2, each with 16- and 32 Bit resolution.

Technical Manual
Configuration tool for Profibus-DP 2 Device Profile - Profile for Encoder
This profile describes a manufacturer-independent and mandatory determination of the interface for encoders. It is defined in the protocol, which Profibus functions are used as well as how they are to be used. This standard permits an open manufacturer-independent bus system. The device profile is divided into two object classes:
• Class C1 describes all the basic functions, which the encoder should contain.
• Class C2 contains a number of extended functions, which must either be supported by encoders of this class (Mandatory) or which are optional. Class C2 devices thus contain all the C1 and C2 mandatory functions, as well as additional manufacturer-dependent optional
functions. An address area is also defined in the profile, which can be reserved for a manufacturer’s own proprietary special functions.
3 Scaling
With Standard Scaling, scaling will be done as follows:
o With MUR and TMR
o One revolution is equivalent exactly to MUR = TMR values
With Alternative Scaling, scaling will be done as follows:
o With NDR and TMR
o NDR revolutions are equivalent exactly to the TMR values
Positionscaled = ((Positionunscaled / Singleturn-resolution) * MUR) % TMR
Positionscaled = ((Positionunscaled / (NDR * Singleturn-resolution)) * TMR) % TMR
MUR TMR NDR

Class 2 32-Bit resolution, Input/Output consistent:
The encoder uses 2 input words and 2 output words, which are each consistently transmitted over the bus.
Class 2 32-Bit resolution, Input consistent:
The encoder uses 2 input words, which are each consistently transmitted over the bus. Class 1 16-Bit resolution, Input/Output consistent:
The encoder uses 1 input word and 1 output word, which are each consistently transmitted over the bus.
Class 1 16-Bit resolution, Input consistent:
The encoder uses 1 input word, which is consistently transmitted over the bus.

Class 2 32-Bit resolution MUR=13Bit,TMR=25Bit
Configuration tool for Profibus-DP Scaling on, 25 Bit total resolution
The encoder uses 2 input words and 2 output words, which are each consistently transmitted over the bus.
6 Preset setting
In the mode ‘Class 2’ the encoder can be adjusted over the PROFIBUS to any position value in the value range of 27 Bit or 15 Bit.
This occurs by setting the most significant bit (MSB) of the output data (2^31 for configuration Class 2 - 32 Bit or 2^15 for configuration Class 2 - 16 Bit).
The Preset Value that is transmitted in the data bytes 1 - 4 is accepted as the position value with the rising edge of Bit 31 (=Bit 7 of data byte 3). The encoder then continues counting from this position. A new adjustment is then only possible after the control bit has been reset. There is no acknowledgment of this action via the inputs.

Configuration tool for Profibus-DP 9 Installation of the Profibus DP Mastersimulator
The PROFIBUS DP Master Simulator is an easy to use software for data exchange with PROFIBUS slaves of many suppliers via
PROFIBUS DP. The PROFIBUS DP Master Simulator can exchange data with many PROFIBUS slaves even without GSD-file or type-file. The PROFIBUS slaves can be put into operation with the default I/O window. Input data can be read and output data can be written.
Furthermore the PROFIBUS DP Master Simulator also processes GSD-files. User parameters can be edited and the configuration can be modified and stored.
The PROFIBUS station address can be changed as well with the PROFIBUS DP Master Simulator, this is useful for PROFIBUS I/O modules in protection class IP67 without addressing switches.
The PROFIBUS DP Master Simulator offers the possibility to scan a PROFIBUS network for connected slaves and display them in a graphical way. In this case the PROFIBUS UART has to be connected directly to a PROFIBUS slave. The I/O data and the PROFIBUS user diagnosis can be displayed binary, hexadecimal and now also as ASCII code. The PROFIBUS output data can be transmitted consistently to the PROFIBUS slave. In type mode it is possible to set an output as long as the mouse button is pressed.
The PROFIBUS Master Simulator consists of the software and the PROFIBUS UART which is the ideal interface converter between the RS 232 interface of a PC and the PROFIBUS slave. The UART does not need any additional external power supply. Therefore it is also suitable for mobile use with a laptop or a notebook.
The PROFIBUS UART is simply inserted between the PROFIBUS slave and RS 232 connector cable. Also a simple USB-RS232
Adapter is possible to establish a connection between the Master Simulator (PROFIBUS UART) and the adapted PC.
Optional:
If no RS-232 is available, connect the Profibus UART to the USB Converter.

10 Profibus Predefined Connection Set
The set includes all necessary cables, power supply and converter to establish a simple Profibus network.
Configuration tool for Profibus-DP
Ready to go –
Connect the Encoder Power terminal to the power supply , the cable with the M12 connector to the Encoder BUS OUT terminal and the Profibus UART to the end of SUB-D 9 of the Profibus cable.
The Profibus UART needs an external power of +5VDC. This power may adapted from Profibus external power support (available in the tool package) or from an external power supply.
Be careful with the amount of the power, overload could damage the UART.
Therefore it is also suitable for mobile use with a laptop or a notebook.

In order to carry out a general parameterisation of the device, it is necessary first to select a module from the GSD file (e.g. KUEB5868.GSD).
The configuration program normally provides an input mask (screen) for parameterisation purposes, i.e. for entering the data for
resolution, count direction etc. The individual modules are listed below:
