  NAPOPC_ST DA Server  
     
     

 
   
     
 
      NAPOPC_ST DA Server is a free OPC DA Server (The "OPC" stands for "OLE for Process Control" and the "DA" stands for " Data Access") for ICP DAS products. NAPOPC_ST DA Server provides many benefits to users such as reduce time through lower system integration costs, integrate easily with plug-and-play SCADA/HMI/Database, connect and interoperate easily to custom applications, access to data by anyone in the automation hierarchy, reduce troubleshooting and maintenance cost,write to devices synchronously and asynchronously (not possible before OPC).

Using SCADA/HMI/Database software program, system contacts and obtains data from
NAPOPC_ST DA Server either on the same computer or on another computer. SCADA/HMI/Database makes a request and NAPOPC_ST DA Server fulfills the request
by gathering the data of ICP DAS modules and third-party devices to SCADA/HMI/ Database.
 
     
   
   
     
       User Interface  
 
NAPOPC_ST DA Server is an out-of-process OPC Server which provides an Explorer-style user interface. The left side region of IDE is the tree type structure showing equipments in the Device/Group/Tag tree structure; the right side region is the attribute description for each Group and Tag, all the attributes even those hidden in the setting up dialog box can be displayed in the table, clearly and conveniently. The up side region is a tool icon bar for the functions often used, user can see the graph to know the function of that icon and directly select the needed function.
 
     
      Multi-Thread Communication  
 
NAPOPC_ST DA Server, besides single-thread communication in the equipment communication mechanism, provides multi-thread communication to communicate with each COM Port and each socket in independent thread service. It increases the speed of equipments data integration, and also provides users a flexible planning possibility that users can set the idle time for individual equipment so that equipment polling frequency on the same communication backbone can be regulated according to the actual requirements.

       Auto Search  
 
When users setup the DCON I/O modules (I-7K; I-87K; I-8K; RU/USB-87Pn) that supported by ICP DAS, NAPOPC_ST DA Server provides the “Auto Search” function for users’ convenience. If the equipments are on-line, the users can just enable the “Auto Search” function, and then the NAPOPC_ST DA Server will automatically scan and identify the linked DCON I/O modules and list modules in Device/Group/Tag structure. The NAPOPC_ST DA Server provides a “Monitor” function for users real-time monitoring/controlling the equipments.
 
     
       Auto Generate  
 
If the equipments are off-line, users can directly select the names of I/O modules from the “Device” dialog, and then click on “Generate Tags” function, the NAPOPC_ST DA Server will automatically setup the DCON I/O modules’ attributes in the Device/Group/Tag structure. It is easy to generate a whole set configuration, and doesn’t need to bother about checking each attribute of the DCON I/O modules or setting the corresponding structure.

       Support Modbus Device  
 
NAPOPC_ST DA Server, besides the DCON I/O modules of ICP DAS, supports Modbus based communication I/O modules (M-7K; ET-6000/7000) and programmable automation controllers (PAC: XP-8000 ; XP-8000-CE6 ; WinCon; WinPAC; μPAC; iPAC) by ICP DAS. Through NAPOPC_ST DA Server, the integration with I/O modules and controllers of ICP DAS becomes pretty convenient.
 
     
     Unique Design  
 
In addition to above functions that support the DCON and Modbus I/O modules of ICP DAS, NAPOPC_ST DA Server also provides two unique designs that users can apply NAPOPC_ST DA Server with more flexibility.
Active data transmission mechanism (Client side)
Traditionally, OPC Server acquires equipment data by the way of polling. In NAPOPC_ST DA Server, if processing with the NAPOPC_CE5 DA Server or the UPC equipments, the NAPOPC_ST DA Server is able to actively receive the data from the NAPOPC_CE5 DA Server or UPC equipments. Data transmitted by such an active way can significantly shorten the information update time!

OPC Client can select the document in the NAPOPC_ST DA Server during runtime
According to the scenarios of the OPC Client for different equipment needs, the users may save the different scenario configurations to the separate documents. When the OPC Client launches the NAPOPC_ST DA Server in runtime, OPC Client can select which document to be loaded, not only by NAPOPC_ST DA Server like other OPC Server. This function gives users more flexibility when setting configuration in the OPC Client.

       Database Application - NAPDB  
 
NAPDB, the database system developed by ICP DAS, can be used with the NAPOPC_ST DA Server. The NAPOPC_ST DA Server is ideal integrate with the hardware devices based on various transmission formats (like Modbus TCP, Modbus RTU, DCON, etc.) which are provided by ICP DAS. The device information will be converted to OPC format and then stored in the database by NAPDB. Without any complex programming, the user can easily access the information in the database by NAPDB.

 The features of NAPDB:


Easy to use without any programming.
Support NAPOPC DA Server by using an OPC standard communication protocol.

       Protocol Conversion Application  
 
This application architecture is a NAPOPC_ST DA Server centric Client-Server monitor/control system. By the
NAPOPC_ST DA Server, the data of equipments are collected together and provides for use of several clients.
It reduces the loading that equipments service for the different clients, and also improves the stability and reliability
of the system. There are three perspectives to be considered in such systems:


Down to the equipment end:
     NAPOPC_ST DA Server is used to integrate the ICP DAS I/O modules and controllers  (PACs) that based on
     DCON & Modbus  protocols, including I-7K, I-8K, I-87K, M-7K, ET-6000/7000, RU-87Pn I/O units/modules,and
     PAC, iPAC, WinCon, WinPAC, XP-8000, XP-8000-CE6 Modbus controllers.


Communication backbone:
     The common communication backbone is the RS-232, RS-485 and 10/100M Ethernet networks. The system
     uses NS-205/208, the industrial switch provided by ICP DAS, to connect with every system units through
     Ethernet, down to integrate with the ICP DAS equipments via DCON & Modbus protocols, up to service the
     application programs in the client end by the COM/DCOM technology.


Up to the client end:
     Users can select the VC, VC #, VB or .NET languages to program the SCADA graphic control applications,
     or can select the third-party SCADA software that based on OPC Client, such as InduSoft, citect, etc, for the
     top-level client applications.

       VxComm Application  
 
Similarly, this application architecture is a NAPOPC_ST DA Server centric Client-Server monitor/control system. The NAPOPC_ST DA Server collects the equipment data together and provides the data for use of several clients. It reduces the loading that equipments servicing for different clients, and also improves the stability and reliability of the system.

In many cases that are different from above typical protocol conversion application, the NAPOPC_ST DA Server often needs to apply communication through several COM Ports with hundreds of ICP DAS DCON I/O modules and those modules, however, are dispersed in many places. If the system directly wires by RS-485, the signal will be attenuated and the cost will be very high. Therefore, in some applications such as community building monitoring, users can take advantage of the existing Ethernet network as the communication backbone and apply some converters to have a number of virtual COM Ports for use of NAPOPC_ST DA Server.

This kind of application combines the DS/PDS-700 Device Server and the VxComm technology to allow maximum 255 virtual COM ports for the communications when the NAPOPC_ST DA Server applies the DCON & Modbus communication. Wherein the communication between the NAPOPC_ST DA Server and the DS/PDS-700 is through the Ethernet network; the communication within DS/PDS-700, I/O modules and controllers is through the
RS-232/RS-485 network.

       Wireless I/O Application  
 
Similarly, this application architecture is a NAPOPC_ST DA Server centric Client-Server monitor/control system. The NAPOPC_ST DA Server collects the equipment data together and provides the data for use of several clients. It reduces the loading that the equipments servicing for different client programs, and also improves the stability and reliability of the system.

In this application, being different from above typical protocol conversion application, the NAPOPC_ST DA Server collects the equipments data by the way of wireless communication and provides them for use of client end. It is time to apply this wireless I/O application, when I/O equipments are located in an area that no Ethernets connection but still near the ISP stations so that it can communicate through the wireless network, such as the environmental monitoring system in the remote mountain.

In this architecture, the users can apply the GSM/GPRS (GTM-201 series) modem and WinPAC controllers provided by ICP DAS. In the NAPOPC_ST DA Server end, the users can use the Ethernet directly, if available. If there is no Ethernet, users can get a public IP via the GPRS of the GTM-201 series. In the WinPAC end, the WinPAC controller not only collects various I/O data, gets the public IP via the GPRS of GTM-201 series, but also transmits the data by batches via Modbus TCP protocol. However, this architecture cannot guarantee the real-time transmission due to the transmission limitation of ISP.
