MOTION CONTROL: Danfoss Drives introduced the VLT® PROFINET MCA120 Option Card, expanding the Ethernet communication capabilities of the VLT® AutomationDriveVLT® AutomationDrive to PROFINET-based networks. This option card handles a single connection with an Actual Packet Interval down to 1ms in both directions, positioning it among the fastest performing PROFINET devices in the market. Additionally, the MCA120 features a built-in web server for remote diagnostics and visual confirmation of basic drive parameters, as well as an email notification that can send an email message to one or more recipients should certain warnings or alarms occur, and/or when those warning or alarms are cleared.
Supported application protocols include PROFINET for control and parameter setting, HTTP (Hypertext Transfer Protocol) for diagnosis via the built-in web server, and SMTP (Simple Mail Transfer Protocol) for email notification. The PROFINET Option Card also supports DHCP (Dynamic Host Configuration Protocol) for automatic IP address configuration, FTP (File Transfer Protocol) for file up- and download, TSC (Transparent Socket Channel) for easy access to drive configuration data from Danfoss’ MCT 10, and DCP (Discovery and Configuration Protocol) for making topology and neighborhood recognition, and IP-address assertion, possible from a PLC.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.

Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
