1.Introduction
The PDS-700 series is a family of Programmable Device Servers, also known as
"Serial-to-Ethernet gateway", that are designed for linking RS-232/422/485 devices to
an 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.
The PDS-700 series includes a powerful and reliable Xserver programming structure
that allows you to design your robust Ethernet applications in one day. The built-in,
high-performance MiniOS7 boots the PDS-700 up in just one second and gives you
fastest responses.
The PPDS-700-MTCP series features true IEEE 802.3af-compliant (classification,
Class 1) Power over Ethernet (PoE) using a standard category 5 Ethernet cable to
receive power from a PoE switch like the NS-205PSE. The PPDS-700-MTCP also
works as a Modbus/TCP to Modbus/RTU gateway that supports most SCADA/HMI
communications based on the Modbus/TCP protocol. The PDSM-700 is the PDS-700
with Metal Case (RoHS) and the PPDSM-700-MTCP is the PPDS-700-MTCP with
Metal Case (RoHS). Metal Case version includes stronger protection than PDS-700
and PPDS-700-MTCP.

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; it also provides a cost-effective solution for
industrial control networks.

PDS Series User Manual ( V1.4, Oct. 2009) ----- 8
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. The
VxComm driver saves time when accessing serial devices through the Ethernet without the
need for reprogramming the COM port software on the PC.

PDS Series User Manual ( V1.4, Oct. 2009) ----- 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.

PDS Series User Manual ( V1.4, Oct. 2009) ----- 10
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; thereby reducing the user’s learning carve.

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:
In the configuration above, Meter-1 is virtualized to link to COM3 of the host PC.
Therefore a program original designed for the MS-COMM standard can access the meter
without any modification.
COM1/2 of the PDS-
700 is mapped to
COM3/4 of
the
host
PC
The original COM1/2
of the host PC
COM1/2 of the PDS-
700 is mapped to
COM5/6 of
the
host
PC

2.2. Ethernet I/O Applications
The PDS series provides 2 types of Ethernet I/O solutions:
1. Linking to I-7000 series modules
2. Built-in DIO (if the module supports the DIO function)
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 COM2 on the PDS-700 can be used to link to I-7000 series
modules.
By using VxComm technology, programs that on the host PC support serial devices
can be upgraded from a RS-485 network to an Ethernet network without requiring any
modifications to the program. Refer to Sec. 2.1 for more information.
Built-in DIO
The DCON protocol is a request
/reply communication. Protocol that
is defined using a simple ASCII
format, such as $AAN, $AASi6,
#AAN, etc. and is used to access
PDS and I-7000/8000/ 87k series I/O
modules.
The DCON protocol command
set for the PDS is introduced in Sec.
7. The protocol allows access the
built-in I/O through the virtual COM Ports mapped to the Port I/O of the PDS in the
VxComm Utility.

PDS Series User Manual ( V1.4, Oct. 2009) ----- 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.
The VxComm approach provides an MS-COMM-compatible interface. Therefore,
previously developed programs should still function without the need for any
modifications.
2.4. Configurable Ethernet Data Logger
Using the VxComm driver, PDS + 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 of 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:

PDS Series User Manual ( V1.4, Oct. 2009) ----- 14
2: Configure the system connection as shown below and click the “Start” button to begin
logging data.
3: Open the log file in Excel to read the log data as shown in the example below:

PDS Series User Manual ( V1.4, Oct. 2009) ----- 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.
