Over the past several decades, industrial networks have made significant strides towards becoming \u201cALL-IP\u201d. Industrial Ethernet is mature. Yet segments of the network persist where serial datacom remains essential. SCADA, industrial-automation, energy-management, and utility networks still require RS\u2011232, RS\u2011422, and RS\u2011485 connections.<\/p>\n\n\n

The relentless march<\/strong> toward IP network infrastructure has edged these legacy serial systems into the margins.  Many solutions in use today require external converters or device servers with dedicated power supplies and additional cabling\u2014all of which increase cost and complexity.  Bulky, standalone serial device servers consume space and require separate mounting\u2014NOT an elegant solution for serial-to-Ethernet connectivity.<\/p>\n\n\n\n

The market wants<\/strong> a seamless solution that enables serial datacom and Ethernet\/IP to coexist while providing fast, easy installation and management. For manufacturing, industrial automation, transportation systems, and energy infrastructure, one recent technological development shows promise:  The new Smart-SFP solutions provide an elegant way to connect essential legacy technology with state-of-the-art IP-network architecture.<\/p>\n\n\n\n

Legacy Serial Devices<\/strong><\/p>\n\n\n\n

Serial RS-232, RS-422, and RS-485 devices are reliable workhorses that perform critical functions. These units remain the backbone of countless industrial operations.  Remote terminal units (RTUs), programmable logic controllers (PLCs), sensors, monitoring devices, and other serial\u2011based equipment continue to support mission\u2011critical processes across manufacturing, transportation, and utility sectors.<\/p>\n\n\n

One such solution is the Connect\u2011IT CIT\u2011SFP Serial Device Server from Patton. The module consolidates traditional device\u2011server functionality into a compact, hot\u2011swappable SFP module. By plugging directly into an Ethernet switch, router, or Internet of Things (IoT) gateway, the module eliminates the need for external adapters, power supplies, and patch cables. The host device provides power, and  RS\u2011232\/422\/485 support is fully software\u2011selectable:  just plug this little widget into your Ethernet switch. The SFP module connects directly to Ethernet, draws power from the host, and VOILA!  Because universal RS interface support is software selectable, you get instant universal RS-you-name-it<\/em> serial connectivity.  <\/p>\n\n\n\n

Patton\u2019s Connect-IT CIT-SFP functions as a device server, terminal server, and serial-over-IP network extender. The unit encapsulates serial data into IP packets for transport via UDP or TCP. The device supports three network architecture scenarios:<\/p>\n\n\n\n
