ioLogik E2210 Helps CNC Machines Monitor More Flexible and Smarter

Project Introduction

CNC (Numerical Control Machine) is the abbreviation of Computer Numerical Control (CNC). It is an automatic machine controlled by a program. The control system can logically process a program having a control code or other symbolic instructions, and decode it by a computer, so that the machine tool performs a prescribed action, and the rough material is processed into a semifinished product part by tool cutting.

A company is a key enterprise engaged in the development of professional airborne equipment in China's industry. There are a large number of CNC machines in its workshops for daily production. However, once an abnormal problem occurs in the production process, it is not easy to be solved; moreover, the utilization rate of each machine tool is not easy to count, which results in cost control being difficult. Not only that, there is a problem of bandwidth shortage in the video surveillance in the factory area. During on-line processing, it is feared that the data will be interrupted and the processing will fail. Therefore, how to effectively monitor a large number of CNC machine tools has become a problem facing the management.

The traditional solution is to connect the CNC to the CNC Server through the PLC, but there are some problems, such as poor real-time performance, because the PLC adopts the polling mechanism. Another problem with polling may lead to increased production costs because polling can easily cause network congestion and cause online processing to fail. In addition, the cost of the network PLC itself is also very high, and it is very expensive to use in this system. Customers want a more cost-effective and flexible solution.

Moxa solution

Moxa's remote automation solution can completely solve the customer's difficulties and make the complexity simple. At this site, Moxa recommended to customers the ioLogik E2210 Active Ethernet Microcontroller, which supports 12 DIs and 8 DOs to meet the needs of multiple digital acquisition points in CNC equipment. Since the plant has set up an Ethernet network, the E2210 has an Ethernet port that can upload data to the main control room in a timely manner.

In terms of real-time, ioLogik E2210 can provide an active and time-based alarm mechanism, no longer using the traditional polling mechanism, the user can customize the alarm status. Once an event occurs, E2210 can actively report the I/O status of the site. This event-triggered alarm method occupies far less bandwidth than traditional polling methods. Therefore, the master control room can obtain the status of the data collection point of the CNC device in real time, and is no longer limited to the time required by the conventional polling. Actual test value of Moxa ioLogik products: Under the full load of the network, the network response speed is 7 times faster than before, and the bandwidth occupancy is reduced by 80%.

With the improvement of factory management level, the demand for CNC monitoring has also been increasing. We can understand whether the CNC can process the normal workpieces by collecting the spindle load. At the same time, in order to ensure the processing quality, the pressure of the cutting fluid is also monitored. This requires the use of simulation. The quantity, together with the original demand for digital quantities, requires the product to have more types of interfaces. Moxa's ioLogik E2242 supports 4 AIs and 12 DI/Os, supports active uploading capabilities and is more in line with CNC monitoring requirements. Not only that, because of the large number of equipment in the CNC plant, a large amount of current interference occurs when the equipment is started up and running. Compared to traditional I/O products, Moxa ioLogik products have industrial grades of PLC, and when there is current interference around them, they can still ensure the normal operation of the products and the data communication is uninterrupted.

The Moxa Ethernet Microcontroller requires no programming and comes with Click&GoTM software setup function. Simply set the conditions of the IF-THEN-ELSE and complete front-end data acquisition, processing, and communication within five minutes. In addition, Active OPC Server is supported to be compatible with SCADA systems and provide seamless integration of ioLogik products and SCADA systems. Different from the traditional polling method, the Active OPC Server can provide Push communication with the HMI/SCADA system through Moxa ioLogik series products, and at the same time provides instant I/O status report. In addition to the Active OPC Server, the ioLogik also provides Modbus/TCP and MXIO (.NET) for easy integration with HMI/SCADA systems.

Compared to PLC, ioLogik E2210 is compact, flexible and cost-effective. The ioLogik E2210's high efficiency, stability, and compatibility are highly appreciated by customers. In the future, CNC monitoring will collect parameters for some analog quantities, such as speed, hydraulic pressure, and power. This requires a richer I/O interface for Ethernet microcontrollers. Moxa can now provide a complete solution on the CNC system: CNC monitoring can use ioLogik series of active Ethernet microcontrollers for data acquisition; CNC online processing can use UC series embedded computers to increase the boot speed and Security; CNC networking can use NPort series serial networking servers to upload serial data to the network. Moxa's complete range of complete solutions will help the CNC machine tools become smarter and more flexible, greatly improving the management level and production efficiency.

1. Buy power banks from qualified factory,do not focus on cheap price only. Batteries, circuit boards have certain fixed costs, higher quality batteries, the higher purchase cost.
2. Better choose poly-mer batteries. Polymer batteries output efficiency is relatively stable, but also has a light weight, safe and efficient.
3. Consider shell beauty at the same time, pay attention to the shell strength and heat resistance.
4. Do not just focus on the conversion rate.
