Courtesy: Wago CorporationWago's Profinet I/O Fieldbus Couplers 750 Series operate as I/O devices in the Profinet network. The couplers identify connected I/O modules and create local process images for one or more controllers. The device ID can be assigned via DCP protocol or set via DIP switch.

The compact couplers come in two versions, 750-375 Standard and 750-377 ECOnomy, with support of Profinet 2.2. Both versions support PROFIEnergy, Profisafe and iPar-Server, Profinet RT and Profinet services such as topology detection and automated device replacement.

The 750-375 Standard features include:

  • Supports up to 250 I/O modules
  • Supports two I/O controllers and one I/O supervisor
  • Supplies 1700mA of internal power
  • 1024 byte input/output process image

The 750-377 ECOnomy:

  • Supports up to 64 I/O modules
  • Supports one I/O controller and one I/O supervisor
  • Supplies 700mA of internal power
  • 256 byte input/output process image

The couplers offer transmission cycle times with a minimum of 1 ms. The Profinet I/O Fieldbus Couplers also offer a built-in Ethernet switch, flexible I/O platform and available connection to 400+ I/O modules.

The couplers can be used in automation applications where Profinet is required including textile, process control, packaging, automotive, facility management, OEM equipment, utilities and others.

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.
