Learn About Using SNAP I/O in Allen-Bradley Logix PLC Systems

Using reliable SNAP I/O as intelligent remote I/O with an Allen-Bradley ControlLogix or CompactLogix system is a new way to expand a PLC system.
But is it true you can add I/O points without impacting performance on the controller? Can you really get PID loop control, temperature conversion, pulsing, and a whole lot of other I/O functions at the local level without programming?
It is, and you can. Come to a technical seminar in a city near you and get all your questions about SNAP I/O and Logix systems answered.

Hot Tips from PSG: Measuring RPM
Opto 22's Product Support Group (PSG) develops some helpful tips as they work with customers who contact them for free product support.
Measuring RPM (revolutions per minute) is important when you're controlling or monitoring the speed of motors, conveyors, turbines, and the like. But it can be tricky.
Our new technical note on the subject discusses field devices—such as shaft encoders and proximity sensors—and methods you can use to measure the rotational speed of a shaft in RPM.
Along with the tech note is a new sample PAC Control strategy that demonstrates how to measure RPM. You can use the sample as a base to start your own strategy or adapt the logic to an existing strategy.
The sample strategy is compatible with PAC Control Professional version R8.1d. In PAC Project R8.2003 and higher, the sample is included when you install PAC Project Pro.
Read the technical note.

Rack-Mounted PACs—What's the Difference?
You can choose between two rack-mounted programmable automation controllers (PACs): the SNAP-PAC-R1 and the SNAP-PAC-R2. But which one is better?
Our new OptoMinute video answers that question in just 60 seconds. Engineer Alexi Beck Gray summarizes the similarities and differences between the R1 and the R2, so you can choose the one that's right for your application.

OptoVideos Hit It Big
A lot of customers learn from the videos on our website, and the industry is noticing. An article in Design News last month featured our temperature monitoring video, and Design World embedded the video in a recent article on thermocouples. This video talks about the kinds of field devices used to monitor temperature—thermocouples, ICTDs, RTDs—and the SNAP I/O modules that work with those devices.
Presented by Opto 22 engineers, OptoVideos primarily aim to inform rather than sell—but we figure the more you see of our PACs, software, and I/O, the more you'll want them!
