The Serial Revolution - Establishing Global Access to Serial Ports
|
From B&B Electronics Manufacturing Co. Inc.
The integration of legacy serial equipment into modern Industrial Networks presents some unique challenges; among these are reliability, connectivity, and limited range. These issues can be easily resolved. While speed gets public attention for Ethernet, benefits for industrial applications can be summed up in three words: connectivity, distance, stability. In the process of updating a variety of computer systems and hardware configurations, the plant manager of a Midwest manufacturer needed a centralized network that would connect three buildings within three quarters of a mile, plus a couple more several miles away. With a wide array of legacy equipment, primarily utilizing serial connections, the need presented a rather complex challenge, especially since serial connections are limited in terms of distance and networking. The scenario is not uncommon. In fact, as computer software and hardware technologies advance, a massive connectivity gap is growing between perfectly good legacy systems and advanced Data Acquisition (DAQ), Programmable Logic Controllers (PLC), Industrial Computers and other critical systems.
