Project Introduction

Semiconductor plants have one characteristic that in the past has made management difficult. The plants use different types of machines that use different protocols, making it hard to design a coordinated system that can collect, analyze, and process data from all stations in the plant. MOXA's UC-7420 helps solve this problem by providing an "open" programming platform for users to download their own custom protocol conversion software. Data can also be transferred to several backend hosts at the same time.

Protocol Conversion and Front-end Data Processing

The data collected by a FAB floor can come from different devices. One of the tasks that the UC-7420 unit must handle is protocol conversion, since there is no guarantee that all of the devices will use the same protocol. In addition, the UC-7420 can be used to do preliminary data processing before downloading data to the central computer. MOXA's UC-7420 is ideally suited for these tasks, since the user can easily embed a C program that is custom written for the devices used at the station. If future changes involve adding or removing devices, the programmer simply needs to modify the C code, recompile it, and then download the executable program to the UC-7400 unit.

Connecting to the Network and the Internet

In addition to being programmable, MOXA's embedded computers also offer users with an array of connection options. To begin with, data entering the serial ports from attached sensors can be processed and then forwarded through one or both of the dual Ethernet ports to the LAN. One of the serial ports can also be connected to a V.90 or GPRS modem for PPP connections, and a PCMCIA port is available for installing a wireless LAN card for 802.11b/g networks.
