Reliable CNC Communication and Real-time Monitoring

Moxa’s serial-to-Ethernet solutions help factories maintain reliable CNC communications networks for accurate process control. Precise data communication between DNCs and CNCs is crucial for optimizing CNC productivity, since data lost during DNC-to-CNC communications could give rise to a number of production issues and extra costs. Moxa’s serial-to-Ethernet and serial-to-Wi-Fi products are reliable, sturdy, and durable, and provide the technological advances needed to make the most of your DNC solution.

Precision Process Control to Maximize Productivity

Excellent Hardware and Software Design Ensures Zero Packet Loss Transmission

Since CNC machines cannot tolerate data loss, Moxa’s serial-to-Ethernet products are specially designed for industrial applications. The components are selected to ensure that the final hardware design passes high EMI and surge attacks, and is able to operate in wide temperature conditions. The unique hardware design of Moxa’s products guarantees that they will provide highly reliable operation, even in harsh environments, and provide a long product lifecycle. With the excellent quality of the OS driver and prioritized packet transmission design, Moxa’s NPort serial-to-Ethernet device servers ensure that all data transmitted through your factory network arrives as intended. By putting in the effort required to create both an excellent hardware and excellent software design, Moxa ensures that products operate with the highest reliability and provide zero packet loss data transmission. For factories migrating CNC connections from wired to wireless, floor managers can rest assured knowing that their network stations treat serial, Ethernet, and Wi-Fi connections the same with regards to data security and transmission reliability.

On-chip Flow Control for Precise Production

CNC machines often only have a small data buffer, which makes Xon/Xoff flow control a necessary feature for many systems. Device servers need to halt data transfer immediately once they receive the Xoff signal, since otherwise data might be lost or corrupted, causing serious production
issues or financial losses. Effective flow control is important because it increases overall network efficiency. Moxa’s devices utilize on-chip software to achieve the most effective and responsive flow control available.


Save Time and Cost for CNC Expansion and Management

Moxa’s wireless device servers feature a bridge mode that provides both serial and Ethernet ports. In this way, when a factory needs to expand their CNC production line, a device server with bridge mode can be used to connect simultaneously to both a new Ethernet-based CNC and a legacy serial-based CNC. With bridge mode, the same device servers can be used for production line expansion, allowing DNC solution providers to save a lot of time since they do not need to develop a new program to integrate a new device server with their Software. They just need to use minium time to upgrade Software. With Moxa’s I/O solutions, factory production managers can easily monitor machine status using programming free control logic to get real-time CNC production data for easy maintenance and risk control. Moxa’s bridge mode device servers have an extra Ethernet port to transmit I/O signals to control rooms through a wireless Ethernet Bridge, providing significant savings on the wiring cost required to construct an Ethernet infrastructure.
