PDS-8x1 Series User Manual, Version 1.1.2, Apr. 2015 - 6 -

1. Introduction

The PDS-811 and PDS-821 programmable device servers (PDS) are compact, modular, intelligent,

rugged, and are designed for networking RS-232 and RS-422/485 serial devices to an Ethernet

network. The PDS-811 has one I/O expansion slot, while PDS-821 has two I/O expansion slots that

can be used to attach various 2- or 4-port serial communication modules. Therefore, a maximum of

4 serial ports can be installed on the PDS-811 or a maximum of 8 serial ports can be installed on the

PDS-821.

Note: There is no serial module built-in to the PDS-811 or PDS-821 by default.

The PDS-811 and PDS-821 controllers are equipped with a 2-port 10/100 Base-TX Ethernet Switch

that can be used to connect two network segments. The Ethernet Switch processes and routes data

on the data-link layer (layer 2) of the OSI model to create a different collision domain per switch

port. Using a switch allows you to attain dedicated bandwidth on point-to-point connections with

every computer, and therefore run in full duplex mode with no collisions. Furthermore, the built-in

2-port Ethernet Switch on the PDS-811/821 enables network wiring to be simplified by cascading

your Ethernet devices.

The PDS-8x1 series contains a built-in operating system, the MiniOS7, which offers a stable and high

performance environment that is similar to DOS. The MiniOS7 can boot up the PDS-8x1 series

within just one second, with the added benefit of no virus problems and a small footprint.

Furthermore, the PDS-8x1 series is designed for low power consumption, maintenance elimination

(no hard disk and no fan), and is constructed from fire retardant materials (UL94-V0 level) with a

robust case.

1.2 Ethernet Solutions

Nowadays, the Ethernet protocol has become the foremost standard for local area networks.

Connectivity via the Internet is now common in many of the latest applications from home

appliances, to vending machines, to testing equipment, to UPS, etc. An Ethernet network can link

office automation and industrial control networks, access remote systems and share data and

information between machines from multiple vendors, and also provides a cost-effective solution

for industrial control networks.

1.3 VxComm Technology

In general, writing a TCP/IP program is more difficult than writing a COM Port program. Another

issue is that perhaps the existing the COM Port communication system was built many years ago

and is now outdated.

As a result, a new technology, VxComm was developed to virtualize the COM Ports of the PDS-8x1

controller to allow up to 256 COM Ports to be used on a central computer. The VxComm driver

saves time when accessing serial devices through the Ethernet without the need for

reprogramming the COM Port software on the PC.

Page 10

Programmable Device Server with I/O Expansion Slot(s)

PDS-8x1 Series User Manual, Version 1.1.2, Apr. 2015 - 10 -

The VxComm driver controls all the details of the Ethernet TCP/IP programming technique,

meaning that, with the assistance of PDS-8x1 controller and VxComm technology, your COM Port

program will be able to access your serial devices through the Ethernet in the same way as through

a COM Port.

PDS-8x1 Series User Manual, Version 1.1.2, Apr. 2015 - 11 -

1.4 Web Server Technology

Web server technology enables the PDS-8x1 controller to be configured via a standard web browser

interface, e.g. Google Chrome, Internet Explorer, or Firefox, etc. This means that it is easy to check

the configuration of the PDS-8x1 controller via an Ethernet network without needing to install any

other software tools, thereby reducing the learning curve required for maintaining the device.

Page 39

Programmable Device Server with I/O Expansion Slot(s)

PDS-8x1 Series User Manual, Version 1.1.2, Apr. 2015 - 39 -

The following is an overview of the parameters contained in the Network Settings section:

Item

Description

Default

IP Address

If no DHCP server is installed on the network, the network settings

can be configured manually.

Subnet Mask

This parameter is used to assign the subnet mask for the PDS-8x1

controller. The subnet mask indicates which portion of the IP address

is used to identify the local network or subnet.

Gateway

This parameter is used to assign the IP Address of the Gateway to be

used by the PDS-8x1 controller. A Gateway (or router) is a device that

is used to connect an individual network to one or more additional

networks.

DHCP Client

This parameter is used to enable or disable DHCP Client configuration

function. It is recommended that the DHCP Client setting is kept as

disabled, and using static network settings. This ensures your PDS-

8x1 controller always using a fixed IP address, and you don’t need to

configure the virtual COM mappings again and again.

0 = Disabled, 1 = Enabled

UDP Search

This parameter is used to enable or disable UDP

Search function.

0 = Disabled

1 = Enabled

2 = Enable the UDP Search function until another

client is connected.

By keeping the UDP search setting as 2, the PDS-8x1

controller loading will be reduced. The VxComm

Utility will not be able to search for this module until

this module’s clients are all disconnected.

Command Port

This parameter is used to configure the TCP Command Port to a custom value depending on your requirement. Note that if the TCP Command Port configuration setting is completed, the TCP port of serial port will be change, as follows: COM1= TCP Command Port + 1 COM2= TCP Command Port + 2 …., and so on.

The default TCP Command Port is 10000. Thus, the

serial COM port1/port2 is 10001/10002, and so on.

10000

Page 40

Programmable Device Server with I/O Expansion Slot(s)

PDS-8x1 Series User Manual, Version 1.1.2, Apr. 2015 - 40 -

Web Server

This parameter is used to enable or disable Web

Server function.

0 = Disabled, 1 = Enabled

Telnet Server

This parameter is used to enable or disable Telnet

Server function.

0 = Disabled, 1 = Enabled

Ping Gateway at start

If the setting is 1 (enabled), the PDS-8x1 controller will

send a ping packet to the gateway during the power-

on stage. It is used to inform the gateway that a PDS-

8x1 controller (itself) has joined the network.

0 = Disabled, 1 = Enabled

(Disabled)

TCP ACK Delay (ms)

PDS-8x1 controller does not want to send an empty

ACK followed by a TCP data packet 1ms later, every

time. So it delays a little (TCP ACK Delay), and then

can combine the ACK and data packet into one. This

efficiency reduces the number of packets and

reduces network loadings.

50 ms

Broadcast

This parameter is used to receive or reject UDP

broadcast packets.

1 = receive UDP broadcast packets 0 = reject UDP broadcast packets

Connection WDT

timeout (ms)

If the PDS-8x1 controller does not receive any data

from a client PC within the period of the “Connection

WDT timeout”, the module will close the connection

to the client.

0 = Disabled, Min. setting value = 10000

(Disabled)

Network WDT timeout

(System Timeout) (ms)

If the PDS-8x1 controller does not receive any data

from any of the clients within the period of the

“Network WDT timeout”, the module will reboot

itself.

This setting is the same as “SystemTimeout” setting

(unit: ms) on Console/Telnet command, and is the

same as “/STxxx” in command line parameter (unit:

seconds).

(Disabled)

Page 41

Programmable Device Server with I/O Expansion Slot(s)

PDS-8x1 Series User Manual, Version 1.1.2, Apr. 2015 - 41 -

When user uses “config=RESET” Console/Telnet

command to clear the EEPROM, the “Network WDT

timeout” (SystemTimeout, /ST) setting will also be

cleared to 0.

Users have to configure this setting again by

“SystemTimeout” Console/Telnet command.

0 = Disabled, Min. setting value = 30000

Master IP

If the Master IP is set, only the client using Master IP

can change the COM Port configuration. It is to

prevent the COM Port configuration changed by

other clients.

empty

Reset System

If the “Reset System” option is checked, the PDS-8x1 controller will

reboot itself after the saving operation is complete, otherwise the

original settings will still be valid until the next power-on.

5. Typical Applications

5.1 Virtual COM Application

The PDS-8x1 controller is designed to link RS-232/422/485 devices to an Ethernet network. The

VxComm utility allows the built-in PDS-8x1 COM Port to be virtualized to a standard COM Port of a

host PC, as shown below:

In the configuration above, Meter-1 is virtualized to link to COM3 of the host PC. Therefore, a

program originally designed for the MS-COMM standard can access the meter without the need for

any modification.

PDS-8x1 Series User Manual, Version 1.1.2, Apr. 2015 - 60 -

5.2 Ethernet I/O Applications

Linking to I-7000 series modules

The I-7000 series provides a variety of I/O operations, such as D/I, D/O, A/D, D/A, Counter and Frequency Measurement, etc. The I-7000 series was originally designed to be used with RS-485 networks, so the RS-485 of COM on the PDS-8x1 can be used to link to I-7000 series modules.

By using VxComm technology, programs that support serial devices on the host PC can be upgraded

from an RS-485 network to an Ethernet network without requiring any modifications to the

program.

Configurable Ethernet Data Logger

Using the VxComm driver, the PDS-8x1 + 7000 modules can be virtualized

to become COM Port + 7000 modules located on the host PC, and then

the Data Logger in the DCON Utility can be used to access data related to

the I-7000 from the Ethernet. Signal data originating from the I-7000

modules can be analyzed using MS Excel without the need to write any

custom programs.

1: The DCON utility includes a log function, as show below:

Step 5: Unzip the “7188XW_yyyymmdd.zip” file on the PC.

The “7188XW_yyyymmdd.zip”can be obtained from either the companion CD-ROM, the ICP DAS FTP site,

or the ICP DAS web site. The location of the install files on the CD and the download addresses are shown

below:

CD:\\ NAPDOS\MiniOS7\Utility\

Step 10: Set the Init/Run Switch in “Run Mode” position, and then power-on reboot the PDS-8x1

controller.

Step 11: Execute ping you setting IP (Example: ping 10.0.8.246 –t) using a run command.

Follow the procedure described

below:

1. Click the “Start” button and then

click “Run” to open the “Run

Command” dialog box.

2. In the “Run Command” dialog

box, type “pin 10.0.8.246 -t” in

the “Open:” field.

3. Click the “OK” button to open a

Command Prompt window.

4. The ping results should be smooth

and continuous

In general, if the host PC can ping the PDS-8x1 controller smoothly and continuously, all other

software and drivers for the PDS-8x1 controller will operate correctly. Therefore, users should

ensure that the development PC is able to ping the PDS-8x1 controller smoothly before any further

testing is carried out.

Note:

1. 192.168.255.1 is the default IP of the PDS-8x1 controller. The IP address can be changed

using the instructions in step 8.

2. If the PDS-8x1 cannot be successfully pinged from the PC, refer to step 8 to change the

configuration of the PDS-8x1 controller. (The mask and gateway addresses of PDS-8x1

controller and the PC should make the network definition.)

3. The MAC address of the PDS-8x1 controller should be unique on the same network.

Refer to step 8 for details of how to change the MAC address of the PDS-8x1 controller.

4. Each PDS-8x1 MAC address is unique in the default shipping.

Appendix B: Glossary

1. ARP (Address Resolution Protocol)

The Address Resolution Protocol (ARP) is a telecommunication protocol that is used to convert an

IP address to a physical address, such as an Ethernet address.

Consider two machines A and B that share the same physical network. Each has an assigned IP

address IPA and IPB, and a MAC address, MACA and MACB. The goal is to devise a low-level software

application that hides the MAC addresses and allows higher-level programs to work only with the IP

addresses. Ultimately, however, communication must be carried out by the physical networks using

whatever MAC address scheme the hardware supplies.

Suppose machine A wants to send a packet to machine B across a physical network to which they

are both attached, but A only has the Internet address for B, IPB. The question arises: how does A

map that address to the MAC address for B, MACB?

ARP provides a method of dynamically mapping 32-bit IP address to the corresponding 48-bit MAC

address. The term dynamic is used since the mapping is performed automatically and is normally

not a concern for either the application user or the system administrator.

2. Clients and Servers

The client-server paradigm uses the direction of initiation to categorize whether a program is a

client or server. In general, an application that initiates peer-to-peer communication is called a

client. End users usually invoke client programs when they use network services.

By comparison, a server is any program that waits for incoming requests from a client program. The

server receives a request from a client, performs the necessary actions and returns the result to the

client.
