FUNCTION MODES:
The device has got two functions mode depending of the position of the ‘Dip2 of Dip-Switch A’:
The first, with ‘Dip2 of Dip-Switch A’ at “OFF” position, is used for the normal working of the device.
The second, with ‘Dip2 of Dip-Switch A’ at “ON” position, is used for upload the Project and/or Firmware.
For the operations to follow for the updating, see ‘UPDATE DEVICE’ section.
According to the functioning mode, the LEDs will have specifics functions, see ‘LEDS’ section.
Warning:
Dip1 of ‘Dip-Switch A’ must be always at ON position!

USE OF CONFIGURATION SOFTWARE SW67561:
To configure the Converter, use the available software that runs with Windows called SW67561. It is downloadable on the Pixsys download are ( https://cloud.pixsys.net/ ) and
its operation is described in this document. (This manual is referenced to the last version of the software present on our web site). The software works only on Microsoft Windows
(XP, Vista, Seven, 8, 10; 32/64bit architectures).
When launching the SW67561, the window below appears (Fig. 2).
Note:
It is necessary to have installed .Net Framework 4.

NEW CONFIGURATION / OPEN CONFIGURATION:
The “New Configuration” button creates the folder which contains the entire device’s configuration.
A device’s configuration can also be imported or exported:
To clone the configurations of a Programmable “Profibus Slave / Modbus Master - Converter” in order to
configure another device in the same manner, it is necessary to maintain the folder and all its contents;
To clone a project in order to obtain a different version of the project, it is sufficient to duplicate the project
folder with another name and open the new folder with the button “Open Configuration”.

SOFTWARE OPTIONS:
By pressing the “Settings” ( ) button there is the possibility to change the language and check
the updatings of the software.
In the section “Language” it is possible to change the language of the software.
In the section “Connection Options”, it is possible to check if there are some updatings of the
software in Pixsys srl website.
Checking the option “Check Software Update at Start of Program”, the SW67607 checks
automatically if there are updatings when it is launched.

SET COMMUNICATION:
This section defines the fundamental communication parameter of two buses, Serial and PROFIBUS.
By Pressing the “Set Communication” button from the main window of SW67561 (Fig. 2) the window “Set Communication” appears (Fig. 3).
The Window is divided in three sections, one for the hardware type, one for the Modbus Master and the other for PROFIBUS.
In the “Hardware Type” sections, please select “Hardware With Ethernet”.

slave interrogated (1000mS is the default value);
In the field “Cyclic Delay (ms)” insert the delay between two re uests (10mS is the default value);
If the field “Enable Modbus ony if PROFIBUS is Active” is checked, the converter do the Modbus
re uests only if PROFIBUS connection is established; otherwise the re uests are made also if PROFIBUS is
not operational. (disabled is is the default value);

In the field "Baudrate" the baudrate for the PROFIBUS is defined, please leave it as AUTO;
In the field "Number Byte IN" the number of byte from the slave PROFIBUS to the converter is defined;
In the field "Number Byte OUT" the number of byte from the converter to the slave PROFIBUS is defined.
If the field “Enable Error/Diagnosis for Modbus Slaves” is checked, the converter can advice a problem
with one or more devices in Modbus network. In the field on right is necessary to insert the start byte
address of array OUT where is saved the Diagnosis;
If the field “Enable PROFIBUS Diagosis” is checked, the converter use the Diagnosis to show an error of
one or more Modbus device. (The “Enable Error/Diagnosis for Modbus Slaves” must be selected for enable
this option);
If the field “Enable Modbus Asynchronous Requests” is checked, is possible to send a Modbus Re uest
using some bytes of the PROFIBUS to controll the re uests;
In the field “Start Address Byte IN” the starting address where the gateway send to the PROFIBUS master
the state of Modbus re uest (for more info see the chapter “Async Remote Re uest”). Remember, there are
4 bytes of state of the modbus re uest;
In the field “Start Address Byte OUT” the starting address where the PROFIBUS master send to the
gateway the parameters of the Modbus Re uest (for more info see the chapter “Async Remote Re uest”).
Remember, there are 8 bytes of parameters for the modbus re uest.

ERROR/DIAGNOSIS
By pressing the “Error/Diagnosis” button from the main window for SW67561 (Fig. 2) the window “Error/Diagnosis” appears.
In this window is possible to insert all the Modbus devices checked by the converter.
The table give the position of the bit that are set if the device is in error in the Diagnosis array in PROFIBUS.
The Diagnosis has always 6 byte fixed, then if there is some problem with some Modbus devices it increase the number of
byte.
If there a problem in Modbus side, after the first 6 byte, there is a byte with a fix part (0x40) plus the number of follow bytes
plus 1. For example if you want to monitor 10 Modbus devices you fond the first byte to the value 0x43 followed from 2
other byte that contain the status of each devices. If the bit is to 1 there is a problem on it device. Each byte can contain at
maximum 8 Modbus devices.
For enable this feature you have to checked the “Enable check Modbus Error” option in the Set Communication section.
GSD FI E:
By pressing the “GSD File” button it is possible to save the GSD file for the PROFIBUS side.
With this feature you can save the configuration of the gateway of the PROFIBUS side.
Note:
When you import the .gsd file on your Master PROFIBUS you have to add all the modules that are present inside it.
