Process Automation

One of the difficulties in automating process control is dealing with specialized hardware and difficult programming requirements. Moxa products are designed with open standards and developer-friendly features, making it much easier to integrate almost any type of sensor, device, or machine into an automation system.

UPort 2410 connects observatory equipment

An observatory needed a COM port expansion solution to control the dome, filter-wheels, and telescopes. The astronomical equipment used RS-232 serial interface for advanced controlling and the control side is only equipped with USB ports. The observatory needed a space-saving and easy wiring solution capable of transmitting data between RS-232 and USB interfaces for the astronomical equipment.

Moxa provided the easiest solution for both communication and space requirements in the dome by implementing the UPort 2410 wall-mounted 4-port RS-232 USB to Serial converters. The UPort 2410 comes with up to 921.6 Kbps serial transmissions and Hi-speed USB 2.0 for up to 480 Mbps over USB. All of these features helped to optimize data transmission and real-time data processing for the observatory.

Ultra Low Serial-to-Ethernet Latency in Semiconductor Processing Equipmen

The fabrication of semiconductor wafers is a high precision process that requires over 300 individual steps categorized into various major process groups such as photo-resist, thinfilm, etch, and CMP. Within a typical thinfilm or etch device, there are many built-in serial devices such as vacuum turbo pumps, RF generators, and RF matches, all controlled by an internal PC. A company that produces thinfilm and etch process equipment was looking to develop a new-generation device communication solution. This solution will enable the serial devices to be controlled by a remote PC located in the control island of the semiconductor factory and will result in better control of the serial devices for finer precision. With this new solution, semiconductor makers can easily retrieve the running parameters of the devices and remotely place process recipes to the process equipment. Currently, a majority of semiconductor fabrication factories use Ethernet communication as one part of their backbone network, and for this reason the company opted for a serial-to-Ethernet solution with:

•WinCE driver for managing devices on a WinCE platform 
•Ultra low latency for retrieving running parameters and placing process recipes, which are extremely time critical (the time is calculated in milliseconds). 
•High MTBF since even a small pause in device connections can cause huge losses.

Moxa Solution

Moxa's NPort® 6650-8 terminal servers were chosen since they meet all of the company's requirements. Each piece of thinfilm and etch process equipment is equipped with two chambers that run the process individually. Each chamber is equipped with a vacuum turbo pump, RF generator, and RF match, all of which use RS-232 communication. Inside the process equipment you will find a pair of NPort® 6650-8 device servers that connect the serial devices to Ethernet, allowing the devices to be controlled and monitored by the remote PC. The company uses Moxa's WinCE Real COM driver on the NPort® 6650-8 to connect the devices to the remote PC.
