Generate Electric Power Solutions Research
Project Introduction:
My customer want to make a research for the “generate electric power by water ”, “generate electric power by wind” and “generate electric power by gas ”. All of these three systems were using Allen Bradley SLC 500 series PLC to control the equipments. We also need to use iFix SCADA to monitor and control the PLC and generate the analyzed report. iFix SCADA is a famous products by the GE company. It’s stable and easy to use. This is why my customer appointed to use it.
System Requirement:

Conclusions:
Nearly all of the SCADA do not have the useful report module. We system integrator should use more than five SCADA for the different kind of customers. The report modules are different and nobody will spend time to learn all. These is why we use OPC Server to link with SCADA and our report module which designed by VB programming language.
Powerful OPC Server Combine with SCADA and Alarm Call Out System
Project Introduction:
My customer want to monitor all of the signals in the whole factory. They need an alarm system which is monitoring all of the signals. If the value over the limitation, the software will call out through the telephone and inform the operator to manage the emergency events.
System Requirement:
Because various brands of independent PLC systems were used, the customer wanted to build an integrated monitoring system without replacing any existing systems. The most-recommended network solution for data sharing and exchange is an Ethernet network. A web-enabled monitoring system should allow staff to access real-time data from on-site equipment anywhere, anytime. To run an operation without interruption, a redundant operating system is required.
Project Implementation:
The following is a complete list of all products used in this project.

Conclusions:
There are so many devices need to be integrated in the factory. Most of the system integrator or end user use SCADA to complete these task. But sometimes the SCADA can not solve the specific function. We use OPC Server to be the communication base to connect with devices and SCADA. If we need more function to compensate the SCADA. We use VB, .NET or BCB to design the OPC Client program and combine with SCADA. The call out system is one of the OPC integration cases.
Powerful OPC Server Link with Different kind of Software
Project Introduction:
There are so many SCADA in the automation fields. RSView is presented by Allen Bradley Corp. Cimplecity belong to GE and EBI is created by Honeywell. They all only provide their own PLC driver for free. But they provide the OPC client interface for users to connect with the OPC Server . Beside the SCADA software, real time DATABASE software are fully supported OPC Client. Such as Honeywell PHD, PI, InfoPlus21, Intellution iH ..etc. These software are what we integrated before.
System Requirement:

System Description:
Different software uses OPC Server to integrate with each other.
Conclusions:
OPC (OLE for Process Control ) becomes a standard software interface in the world. So many companies use OPC Server to integrate different kind of software. The programmers do not care about the communication skills. Just let OPC Server to handle all of the communication affairs.
Cement Factory Case
Project Introduction:
Taiwan Cement Company used a lot of Allen Bradley PLC5 PLC in recipe system. The PLC5 is an old type of AB PLC. It’s difficult to use VB program to connect. Our customer used OPCTechs PLC5 OPC Server combine with VB programming language.
System Requirement:
System Diagram:
Conclusions:
OPC Server is a standard integration interface in the automation fields. It’s suitable to combine with different kind of software. We use OPC Server to connect with VB, .Net, C++, Delphi, Excel …etc. It’s stable and easy to manage the data.
Integration Different Kinds of PLC
Project Introduction:
Generally, MIS department exists in well-established company to collect instrument operating data to analyze the data and give report, also, of course to write PC program. Data collection is always an annoying trouble for most MIS engineers because all the programs are designed with different programming languages. Now, with the help of OPC Server, all the problems mentioned above can be solved easily rising the efficiency. OPCTechs Technology Corp. provides OPC Server for most popular PLC. Programs written by different programming languages could also communicate through Data Exchange OPC Server.
System Requirement:
System Diagram:
Conclusions:
OPCTechs OPC Server support part of popular devices, such as all series of Melsec PLC, Omron PLC and AB PLC. Moreover, we also provide well organized structure of OPC Server and Client, so all the monitoring program and self-developed program could be integrated with each other easily. Time for developing Driver program could be saved.
