  • Page 6: Introduction

    Ethernet network. The user-friendly VxComm Driver/Utility allows users to easily turn the built-in COM ports of the PDS-700 series into standard COM ports on a PC. By virtue of its protocol independence, a small-core OS and high flexibility, the PDS- 700 series is able to meet the demands of every network-enabled application.

  • Page 7: Why Ethernets

    1.1. Why Ethernet Solutions? Nowadays, the Ethernet protocol has become the de-facto standard for local area networks. Via the Internet, connectivity is occurring everywhere, 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 multivendor machines;...

  • Page 8: Why V X Commt

    1.2. Why VxComm Technology? In general, writing a TCP/IP program is more difficult than a COM port program, or the COM port communication system was built many years ago. As a result, a new technology, VxComm was developed to virtualize the COM ports of the PDS to allow up to 256 COM Ports to be used on the central computer.
  • Page 9 The VxComm driver controls all the details of the Ethernet TCP/IP programming technique; your COM port program will be able to access your serial devices through Ethernet in the same way as through COM port with the assistance of PDS and VxComm technology.

  • Page 10: Why Web Servert

    1.3. Why Web Server Technology? Web server technology enables configuration of the PDS via a standard web browser interface, e.g. Internet Explorer, FireFox or Mozilla, etc. This means that it is easy to check the configuration of the PDS via an Ethernet network without needing to install any other software tools;...

    2. Typical Applications for the PDS 2.1. RS-232/485/422 Device Networking --- Using Virtual COM Technology --- The PDS series is designed to link RS-232/485/422 devices to an Ethernet network. The VxComm utility allows the built-in PDS COM Port to be virtualized to a standard COM Port of the host PC as shown below: The original COM1/2 of the host PC...
  • Page 12 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 COM2 on the PDS-700 can be used to link to I-7000 series modules.
  • Page 13 2.3. Linking I-7000 Series Modules to an Ethernet Network The I-7000 family was originally designed for use with an RS-485 network. They are very robust and work well under the harsh industrial environments. The PDS enables I-7000 modules to be upgraded to an Ethernet solution. Linking I- 7000 modules to an Ethernet combines the advantages of both RS-485 and Ethernet solutions and expands RS-485 applications to the whole world.

  • Page 15 By using the I-7000 DCON utility and MS Excel in conjunction with the VxComm technology, the signal data of I-7000 modules from the Ethernet network can be analyzed without the need to write custom programs. For more information about the log function refer to the online help feature (English and Traditional Chinese) of the DCON utility.

  • Page 177 Glossary 1. Ethernet The term Ethernet generally refers to a standard published in 1982 by Digital Equipment Corp., Intel Corp. and Xerox Corp. Ethernet is the most popular physical layer local area network (LAN) technology today. Ethernet is a best-effort delivery system that uses CSMA/CD technology.
  • Page 178 7. IP (Internet Protocol) address Every interface on an Internet must have a unique IP address (also called an Internet address). These addresses are 32-bit numbers. They are normally written as four decimal numbers, one for each byte of the address such as “192.168.41.1”. This is called dotted-decimal notation.

RARP (Reverse Address Resolution Protocol) RARP provides a method of dynamically mapping 48-bit MAC address to the corresponding 32-bit IP address. 32-bit IP address RARP 48-bit MAC address 12. ICMP (Internet Control Messages Protocol) No system works correctly all the time. ICMP provides a method of communicating between the Internet Protocol software on one machine and the Internet Protocol software on another.
  • Page 180 16. 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 program that initiates peer to peer communication is called a client. End users usually invoke client programs when they use network services.
  • Page 181 1. How to access the remote PDS that placed behind an NAT or firewall? remote site must have a NAT (or a router supports NAT) server. NAT stands for Network Address Translator. By using (configuring) the NAT server, NAT can forword (bypass) all specified tcp port connection to specified PDS devices.

  • Page 184 5. Why doesn't the VxComm Driver (PC) receive data from the PDS series module? Make sure that the PDS series module is operating in mode 0 (/M0). PDS series module has the following two communication modes: Transparent Mode (Multi-echo, shared). In this mode, data is echoed from the COM Ports of the PDS series module to each client that is connected to the PDS series module.
  • Page 185 6. Does the transmission speed become faster when the serial device working with Serial to Ethernet device servers? The speed depends on the applications. For transparent applications, it includes Ethernet latency in transmission and may get slower. But you can improve the communication speed by increasing the baud rate since you placing the device server more close to serial device and reduce the communication distance.
  • Page 186 Xserver applications, it can become faster. User can write their own Xserver applications to acquire data automatically, and then compress and transmit this large amount data at one time. Your application can reach high performance by pre-acquire data before asking by client and then response immediately. Traditional time used RS-232/485/422 transmit time (C * n modules)
  • Page 187 7. Why does the PDS series module fail on a (public) Internet connection? The default IP address of the PDS series module is 192.168.255.1, which can be only used on a private Internet connection. A private network packet will not be routed via a (public) Internet connection, which is the reason why the PDS series module failed on the Internet.

  • Page 189 8. Can I use the SetCommState ( ) API to changes the Baud Rate/data format settings of a virtual COM port? Yes. In a Win32 environment, the CreateFile( ) API should be called to open the COM Port(s) and then the SetCommState( ) API can be used to configure the settings. Third-party tools may provide an OpenCom( ) function for accessing a COM port.
