CHARACTERISTICS: The CNV510-PNET-RTU-A is a PROFINET Slave Modbus Master Converter. It allows the following characteristics: Up to 512 bytes in reading and 512 bytes in writing; Triple isolation between Modbus - Power Supply, Modbus - Ethernet, Power Supply – Ethernet; Two-directional information between Modbus bus and PROFINET bus;...
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’...

LEDS: LEDs that are used to give information of the functioning status. The various meanings of the LEDs are described in the table below. Normal Mode Boot Mode ON: Device powered ON: Device powered 1: ON [supply voltage] (green) OFF: Device not powered OFF: Device not powered ON: PROFINET transmissions present 2: PT [PROFINET state] (yellow)

PROFINET: The PROFINET connection must be made using Connector3 with at least a Category 5E cable. The maximum length of the cable should not exceed 100m. The cable must conform to the T568 norms relative to connections in cat.5 up to 100 Mbps. To connect the device to an Hub/Switch is recommended the use of a straight cable, to connect the device to a PC/PLC/other is recommended the use of a cross cable.

RS485: For terminate the RS485 line with a 120 resistor it is necessary to put ON dip 1, like in figure. The maximum length of the cable should be 1200m (4000 feet). Here some codes of cables: Belden: p/n 8132 - 2x 28AWG stranded twisted pairs conductor + foil shield + braid shield; Belden p/n 82842 - 2x 24AWG stranded twisted pairs conductor + foil shield + braid shield;...

USE OF CONFIGURATION SOFTWARE SW67602: To configure the Converter, use the available software that runs with Windows called SW67602. 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;...
NEW CONFIGURATION / OPEN CONFIGURATION: “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 “PROFINET 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;...
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 compositor in Pixsys srl website. Checking the option “Check Software Update at Start of...
SET COMMUNICATION: This section defines the fundamental communication parameters of two buses, PROFINET and Modbus. By Pressing the “Set Communication” button from the main window for SW67602 (Fig. 2) the window “Set Communication” appears (Fig. 3). The window is divided in two sections, one for the PROFINET and the other for the Modbus Master. The means of the fields for “PROFINET”...
SET ACCESS: By pressing the “Set Access” button from the main window for SW67602 (Fig. 2) the window “Set Access” appears. This window is divided in two parts, the "Modbus Read" (Fig. 4) and the "Modbus Write" (Fig. 5). The first part "Modbus Read" is used to read the data from the Modbus slaves, and make them available to read from the Master PROFINET. The second part "Modbus Write "...

ODBUS RITE The means of the fields are: In the field “Slave ID” is defined the address of the Modbus device that you have to write; In the field “Type” insert the data type of the register you would like to read. You can choose between the following: Coil Status;...
UPDATE DEVICE: By pressing the “Update Device” button it is possible to load the created configuration into the device; and also the Firmware, if is necessary. If you don’t know the actual IP address of the device you have to use this procedure: Turn off the Device;...
Page 19
If you know the actual IP address of the device, you must use this procedure: Turn on the Device with the Ethernet cable inserted; Insert the actual IP of the Converter; Press the “Ping” button, must appear “Device Found!”; Press the “Next” button; Select which operations you want to do;...
Page 20
MODBUS DIAGNOSTIC OVER PROFINET: During the normal functioning of the device, if all the programmed Modbus requests have received a valid reply (not an exception error), every PROFINET frame has the "Data Status" byte at the value of 0x35. Otherwise, if at least one Modbus reply is not valid, the "Data Status" byte assumes the value 0x15; that means "Problem Indicator". If this happens, using the port 5000 there is a UDP message that is possible to send in order to understand which Modbus modules have generated that error.
PLC CONFIGURATION: The configuration and commissioning of the PROFINET Converter as described on the following pages was accomplished with the help of the TIA Portal V11-software by Siemens. In the case of using a control system from another supplier, refer to attend to the associated documentation. Note: Please follow the steps below in the exact order they are described! Install the description file .GSD of the module.

2) Press the “Devices and networks” button (1), from the right drop-down menu, under “Other field devicesPROFINET IOGateway ADFweb HD67602” double click on “Serial” module (2). Note: If you have installed more than one .xml file, go to the Information section and in the “Version” field select the correct .xml file (3), before double clicking on “Serial” module pag.

ADVANCED FUNCTIONS: In the CNV510-PNET-RTU-A are implemented some advanced commands that allows to check the functioning of the converter and send some Modbus commands directly from Ethernet side. To use them, it is necessary to send UDP messages to the port 5000. The function of each command and the structure of the UDP messages are described below.
Page 27
B1 command This command allows to read the status of the enabling/disabling of the Modbus polls. REQ: Byte 0 0xB1 RES: Byte 0 B1/bit0 B1/bit1 B1/bit2 … Bn/bitn 0xB1 Poll 0 Poll 1 Poll 2 … Poll x 1 = Poll disabled 0 = Poll enabled Note: In the UDP message, after the command’s identifier (0xB1), you can read the status of the Modbus Reading requests and then the status of the Modbus writing...
Page 28
B2 command This command allows to see the number of errors for each Modbus poll defined in the section “Set Access”. REQ: Byte 0 0xB2 RES: Byte 0 Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8 …...
Page 29
B3 command This command allows to enable the Transparent: it will be possible to send Modbus commands directly from Ethernet side. The converter will become completely transparent. Byte 0 Byte 1 0xB3 Enabling/disabling of Transparent Mode 0x01 = Poll disabled 0x00 = Poll enabled If the message is received correctly, the same message will be sent back by the converter.
Page 30
B5 command This command allows to enable/disable the polling to a single Modbus slave. REQ: Byte 0 Byte 1 Byte 2 0xB5 Slave ID 0x00/0x01 0x01 = Disable polling for Modbus slave 0x00 = Enable polling for Modbus slave If the message is received correctly, the same message will be sent back by the converter. Example: They are connected 3 Modbus slaves (Modbus IDs 1, 2, 3) to the converter and we want to stop the polling to the slave with ID = 2.
Page 31
B6 command This command allows to enable/disable a single poll on Modbus side. REQ: Byte 0 Byte 1 Byte 2 0xB6 Poll No 0x00/0x01 0x01 = Disable poll 0x00 = Enable poll If the message is received correctly, the same message will be sent back by the converter. Example: In the section “Set Access“...
