Courtesy: EatonEaton Corporation's C441 Ethernet series of communications cards allow customers to select from Ethernet/IP, Modbus TCP, HTTP web services and Modbus RTU communication protocols in a single card. The added communications provide electrical original equipment manufacturers (OEMs) and industrial customers, as well as machinery OEMs and panel builders, with flexible communication options to configure, control and monitor their systems. 

It is compatible with Eaton C440, XTOE and C441 electronic motor protection relays, S611 soft starters, and can be used as stand-alone input/output (IO). Now, the suite of protocols available for Eaton motor protection and soft starter solutions includes Profibus, Modbus TCP and RTU, DeviceNet, and EtherNet/IP.

Integral web services provide an easy-to-use web-based graphical user interface (GUI) to make it easier to recognize potential problems. Using a laptop or smart device, customers can drill down to a given load by entering an IP address into their web browser. With four levels of access, the cards ensure only those with credentials have access to critical or sensitive functions.

Problems can be addressed in real time with intelligent monitoring readouts from starters and onboard available four digital inputs (120 volts alternating current or 24 volts direct current) and two discrete relay outputs. With a dual port switch, the Ethernet card allows for easy daisy chaining and reliable ring configurations. Additionally, customers have the ability to use one network for control and another for monitoring – through the Modbus serial protocol used in parallel with the Ethernet network – allowing redundant communications and greater reliability with a single card.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
