1. APPLICATION

RS-485/Ethernet Wi-Fi converter PD8W type allows master devices to transmit data via a wireless Ethernet Wi-Fi network to the devices with RS-232 and RS-485 interface.

The converter has three operating modes: RealPort network service, serial bridge service with the UDP protocol, TCP Socket service.

In the first and third mode, the switching master device of the system is a PC using Ethernet Wi-Fi interface. In the second mode, the converter works with a device with Master function and RS-232 and RS-485 serial interfaces.

The converter PD8W to work with RealPort network service requires the installation of a virtual serial port driver on a PC with Microsoft

Windows. Thanks to the PD8W type converters, this driver provides the existing master systems, i.e. programs like Lumel Heat and Lumel Energy, the ability to transmit data between devices with RS-485 or RS-232 interface using Ethernet Wi-Fi network (Fig. 1). When used in this way, the converter allows to work with one master computer in the given time.

When using PD8W to support Modbus and Lumbus industrial protocols

- its correct interaction with master systems installed on a PC depends on the built-in mechanisms to control time intervals between the received transmission characters.

Using PD8W in the second mode, the RS-485 bus can be expanded with successive segments using additional PD8W converters and Ethernet Wi-Fi local network. Properly configured, one pair of converters allows to build a system working in the serial bridge mode

(Fig. 2). It is also possible to configure their operation in „one-to-several” mode (as a set including up to 65 converters – Fig. 3). Function 2 of the converter operates in the Ethernet Wi-Fi local network with UDP datagram protocol support.

5

Function 3 operation is very similar to the converter working with

RealPort network service except that it is not required to install software virtual serial port driver on a PC with Windows. Communication between a PC and PD8W converter is via TCP Socket mechanism. In this case, in order to connect to the device, it is necessary to specify an IP address of the converter and a port number (Fig. 1).

7. OPERATING MODE WITH REALPORT SERVICE

The PD8W converter includes the RealPort network service licensed by Digi Inc. that enables communication via Wi-Fi with PCs running Windows OS.

Installation of RealPort driver for Windows adds another so-called virtual COM port to the list of ports available on the computer.

This port is virtual hardware - thanks to software emulation of a typical serial interface.

Use of the additional virtual COM ports can replace serial communication with Ethernet communication.

60

PD8W converter design allows only one network connection via RealPort service at a time. It means that only one PC with any IP address can communicate with the converter via a virtual serial port. The service is currently not available for other computers and therefore, there is an error message on their screens.

7.1. RealPort service driver file information

RealPort service driver files are available on the enclosed CD.

There are versions for two different Windows systems in two directories:

- version for MS Windows 98 and MS Windows Me,

- version for MS Windows 2000, MS Windows XP,

- version for MS Windows Vista and MS Windows 7.

You need to install the appropriate version of the RealPort driver depending on the system version running on a computer.

Details of service driver installation for Windows are available on the website of each PD8W converter.

7.2. Example of driver installation in Windows XP

To install the RealPort service driver in the popular operating system such as Microsoft Windows XP, please follow these steps (installation on other Windows versions differs insignificantly):

1. Click Start button, indicate the command Settings, click the

command Control Panel.

2. Double-click the Add/Remove Hardware icon to open the

Add Hardware Wizard. Click Next and click again Next.

NOTE: The Add/Remove Hardware Wizard is searching for

new devices.

3. If prompted Is the hardware connected?, click Yes, I have already

connected the hardware. and click Next.

4. Select from the list Add a new hardware device and click Next.

5. Select Install the hardware that I manually select from a list

(Advanced) and click Next.

6. Select from the list Multi-port serial adapters and click Next.

7. Click Have disk... .

8. Enter the path to the RealPort file and click OK or Browse

to select the files.

9. Select the file digirip.inf, click Open and then click OK.

10. Select on the list Model installed device Standard RealPort

Device (or Digi Connect WI-ME in case of Windows 98/ME), click

61

Next and click again Next.

11. In the dialog box Add Digi Hardware Wizard enter PD8W

converter IP address and leave unchanged the port number (771).

Click Next.

12. In case of Windows 98/ME, in the field Name enter a custom

name (e.g. Test) for the PD8W converter for easy identification

during the operation. Leave the number of PD8W converter serial

ports unchanged (1).

13. Click Next and then Finish.

14. Confirm the next message to complete the RealPort

installation.

7.3. RealPort driver configuration in Windows XP

The RealPort driver must also be configured using the Windows Device Manager after a successful installation by the previous section. To do this, follow these steps:

1. Click Start button, indicate the command Settings, click the command Control Panel.

2. Double-click the System icon to open the System Properties window. Select the System tab and click the Device Manager button.

3. After the Device Manager window shows up (Fig. 61) in the tree of available devices, expand the branch Ports (COM

and LPT). You can see in this example that there are three serial ports COM1, COM2, LPT1 available. Once RealPort driver is installed, there is port available in a system - virtual

- COM2 - labeled as PD8W Converter Port (Fig. 61).

62

Fig.61. Sample list of devices

4. Expand the branch Multi-port serial adapters (Fig. 61), which shows the PD8W converter installed (in Windows 98 it appears as a „PD8W Converter”).

63

7.4. Example of Lumel Heat and Lumel Process configuration

to work with PD8W

Lumel Heat and Lumel Process systems communicate with industrial devices using serial COM ports.

After the installation of additional virtual serial COM ports you can refer to them in LUMEL Series systems. Enter or change the supervisory appeal to added virtual ports in new or existing applications or system configurations.

The parameter of maximum response time for the slave devices (timeout) available in master systems should be adjusted to the correct value for PD8W. The delay value can be up to 1000 ms and is dependent on: l maximum response time of slave devices with MODBUS

protocol and RS-485 interface, l bandwidth of Ethernet network which the PD8W converter

is connected to.

8. SERIAL BRIDGE MODE WITH THE UDP PROTOCOL

The converter operation in the serial bridge mode enables an expansion of the RS-485 bus by successive segments using additional

PD8W converters and Ethernet Wi-Fi networks. Bridge configuration in a local network allows you to create up to 65 access points between the network RS-485 and Ethernet Wi-Fi using a 65 PD8W converters.

Serial bridge service configuration of a given converter can be divided into four stages:

1. Determination of serial link transmission parameters.

2. Enabling client service, specifying the IP addresses and ports of

servers for other converters, which retransmit serial data

frames.

3. Defining frames caching of a serial transmission protocol.

4. Enabling a service server on the specified IP port of a configured

converter.

Setting the serial bridge operation mode is done by using the configuration application on the webpage of the PD8W, which is called

64

by the user via a web browser installed on user’s PC.

8.1. Determination of serial link transmission parameters

Select device options from the website navigation menu

Serial port to display the serial port settings (see section 6.4.2. Serial

port settings). Please make sure to set the same type of transmission word for each connected converter when setting transmission parameters. The baud rate can be different between segments, but consistent with settings of the devices connected to the RS-485 segment.

8.2. Configuration of client service operation

A user can configure a bridge client by selecting on option

Serial port from the website navigation menu and setting a port profile to

UDP Socket according to Fig. 62.

Fig. 62. Serial port profile setting

65

When a port profile has been already selected, a window will appear as shown in Fig. 63. Select then the highlighted option Change profile which will bring up a window shown in Fig. 62.

Fig. 63. Port profile change

Enable first the UDP client option to begin the configuration process, as shown in Fig. 64. Complete the fields of converters’ IP and ports addresses to retransmit frames the serial data according to following rules:

- In case of connection in the relation 1 to 1, set in each converter the address and IP port of the remaining converter being in relation.

- In case of connection in the relation 1 to several, set in each slave converter the address and IP port of the master converter.

However, in the master converter set all (up to 64) addresses and ports of the slave converters remaining in relation.

The default IP port number for the serial bridge service is

2101. In case of a conflict with another network service using the same port in the given local network - it is possible to change its number - both for the bridge service server and the client.

66

After making changes, click Apply button to save them.

To set the new configuration, restart the device.

9. OPERATING MODE WITH TCP SOCKET SERVICE

Operation with TCP Socket service mode is very similar to the mode with Real Port service. The only difference is the way of communication with the PD8W device, which in this case, a direct

TCP/IP connection is used and providing PD8W IP address and a port number.

TCP Socket service configuration of the given converter can be divided into three stages:

1. Determination of serial link transmission parameters.

2. Defining frames caching of a serial transmission protocol.

3. Enabling a service server on the specified IP port of a configured

converter.

Setting the serial bridge operation mode is done by using the configuration application on the webpage of the PD8W, which is called by the user via a web browser installed on user’s PC.

Enabling TCP Socket mode is similar to the UDP Socket, select from the left side of a website navigation menu an option Serial Port and set a port profile to TCP Socket according to Fig. 65.

68
