TAK/OEE system

The TAK/OEE system is an excellent tool that enables you to increase the productivity of your industry, There are several levels of the system to calculate the value, so here we will classify the operations, from the easiest to the most complex.

The first level is a system based on historical data, with little details to get an idea of the current situation, to assess the potential for improvement.

The second level is a system that relies on the information entered by operators without communication. Therefore, relatively simple methods are used with input fields, database and report management functions, to generate information about significant losses.

The third level is a system with specific equipment connected to the internet through the PLC system. Thus, information about downtime can be obtained in an excellent manner, which increases the level of credibility in the data produced. But, even with this third level system, the operator will need to record the reason for the downtime, because the equipment will not know whether the downtime is due to failure, or due to a lack of demand.

The fourth level is the production control system for the entire factory, which is the most complex to reach successfully. At most times, data management is required, with intelligence business solutions, to create reports. In that way, the operator can get an overview of the entire factory at the same time.

To work with the TAK/OEE system, all employees must learn how to use it, and there should be a strategy to employ the new information. Remember, the more complex system level you choose will enable you to improve your factory continuously.

Also, remember that equipment must be maintained to keep it safe and reliable over the long term. Thus, TAK/OEE planning and proper maintenance help minimise downtime.

Object Linking and Embedding for Process Control “OPC”

OPC stands for Object Linking and Embedding for Process Control. It fills the gap between Windows applications and on-site process control applications.

Before OPC, each application developer had to write a dedicated interface function in order to access data information from field devices.

Due to the continuous upgrading of products and the wide variety of field devices, developers previously had plenty of work to do, so they needed a device driver with high efficiency, reliability and openness.

That’s why the OPC standard appeared, it’s based on Microsoft’s OLE technology, which allows multiple computers to exchange documents.

It is possible to create an open inter-operable control system software with DCOM technology and OPC, The task of developing the access interface is left to the hardware manufacturer or third-party manufacturer. When the OPC controls the user/server mode, the OPC server will solve the contradiction between the software and hardware manufacturers, completes the integration of the system, and improves the system.

OPC is a software interface standard between a data source (OPC server) and a user of data (OPC application). The data source can be a control device, such as a PLC, a DCS, or a bar-code reader. Depending on the composition of the control system, the OPC server as the data source can be either a local OPC server running on the same computer as the OPC application or a remote OPC server running on another computer. The OPC interface is an interface standard with high thickness flexibility for many systems.

OPC is very important because in industrial control systems, different vendors need to exchange data between devices. The data needs to be accessed from one manufacturer to another manufacturer, to be docked with their production control system. It is obviously impossible to develop a proprietary agreement, therefore, the OPC is adopted to solve this problem.
