In PCB fields, the recipe control process is very important for production.Users should input 15 levels of temperature, time and pressure parameters for the control process. If the parameters key in wrong, it will lost a lot. So my customer needs a prediction “Trend chart” before the process goes through. There is not any SCADA exist this function. So we use c++ Builder combine with OPC to complete this task. And the rest of the functions we use the Intouch SCADA to implement.
We use three sets of OPC server install in three different industry PCs. We use Intouch SCADA to be the SCADA and implement most of the function. We also use C++ Builder to implement the prediction “Trend Chart” in this system. Because of the high compatibility of the OPCTechs OPC Server between the programming language and the SCADA, this PCB case was finished efficient and smooth.
You can use SCADA to complete most of the cases. But if you feel the function is no way for the SCADA or the function is very difficult for SDADA. We suggest you to use OPC Server and programming language to support the SCADA. The diagram shows you the prediction trend chart.
Due to its powerful, integrated collection of automation tools, Factory Suite 4.0 is chosen as the SCADA software in a factory automation system. Integrated with OPCTechs OPC server and MG5001 Ethernet Data Gateway, Factory Suite 4.0 retrieves real-time data from field equipment and PLC devices from OPCTechs OPC Server. Factory staffs can easily access information through the Ethernet or internet.
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.
The following is a complete list of all OPCTechs OPC server used in this project.Mitsubishi serial PLC OPC Server (include FX, A, Q types)
There are more than 200 sets PLC in a factory. We use MG5001 to be the serial to Ethernet data gateway. We also use Factory Suite 4.0 SCADA to connect with five different types of OPC Server. The client PC could use Google Chrome to browse the screen of the SCADA server.There are some programmers use VB, C++, VB.Net to design the software for so many single machine. They want to put the signals on the Factory Suite 4.0 SCADA. So we design the DataExchange OPC for various of programming language interchange the data.
OPC Server could easily connect with different kind of device protocols. And they can help different kinds of software or programming languages to integrate together. Programming can easily help the SCADA to solve many difficult functions.
My customer owned a lot of the equipments to produces VCD and DVD products. They have to develop the MES system but no ideas how to fetch the data from PLC. In order to calculate the product and the machine operating rate precisely in each production line. We got to fetch all of the data from many PLC. Then My customer will use VB.Net to analyze it. In this case, most of the PLC are Mitsubishi brand. It includes FX, A, QnA and Q type PLC. Most of the PLC do not have the spare slot to extend the communication module. The only way to fetch the data is from the PLC CPU port.
We have so many customers need to fetch the data from different devices. They have to design the program by programmers, they use different kind of programming language. OPC Server is a standard software interface for integration. You can use any programming language to design the DATASE、REPORT、FIGURES or any kind of your own user interfaces. The OPC server will help you to solve all of the communication affairs.
During the process of packaging goods factory, the parameters inside the equipments would cause a great influence on productions’ quality. Therefore, timely information from the machines could become the key point for high quality productions. Through OPC Serve, all the related data could be sent to the MIS department timely, the engineers would be able to analyze the data he got and make the best policy for producing affairs.
SCADA can not only takes in charge of monitoring the producing condition, also collect data from the equipments through OPC Client of OPC Server. Detecting the equipments’ condition and reveal warning message are also its added value.
In this case, we use ABB Industry IT SCADA, OPCTechs Modbus OPC Server 3.0 and Remote OPC Client to communicate to the power station.
Regardless of the protocols, OPCTechs OPC Server supports most popular SCADA, such as ABB Industry IT, AB RSView32, IFIX, LabVIEW, Indusoft, Honeywell EBI, Advantech, GE Simplicity, Broadwin, SiemensWINCC, Johnson Controls and Wonderware Intouch. OPC Client written by programming language such as CBC, VB, VB.NET, C#, JAVA, J# and ASP.NET could also connect to OPC Server and obtain data easily.
