Connect Opto 22 I/O to Allen-Bradley PLCs

Connect Opto 22 I/O to Allen-Bradley PLCs

EtherNet/IP videoNow you can connect reliable SNAP PAC I/O to an Allen-Bradley ControlLogix® processor, using EtherNet/IP.

  • Use Opto 22 I/O as remote I/O for a ControlLogix system
  • Configure an AB PLC to collect data from a SNAP PAC controller.

That's right. You don't have to choose between AB and Opto—you can use both together.

In our new EtherNet/IP video, Senior Systems Engineer James Davis shows you how easy it is. In just a few minutes, James demonstrates how to configure and program a PLC to talk to SNAP PAC I/O over EtherNet/IP.

You can use any Ethernet-based SNAP PAC System products with EtherNet/IP, including S-series PACs, R-series PACs, EB brains, and the full range of SNAP I/O modules.

Of course you can read and write to I/O, but in addition you can read and write to the flexible Scratch Pad area in SNAP PAC controllers and brains. You also gain the advantages of the SNAP PAC System's distributed control, so processes from counting to PID loop control continue even if communication is lost to the controller.

Watch the EtherNet/IP video.

Hot Tips from Product Support: Sending PAC Files
via FTP

PAC ControlOpto 22's Product Support Group (PSG) develops some helpful tips as they work with customers who contact them for free product support.

Here's a tip about using FTP to send files from a SNAP PAC processor to another device on the network.

All SNAP PAC controllers and EB (Ethernet-based) brains contain at least 2 MB of space in which you can store any types of files. These stored files can be used by a PAC Control strategy or an application you develop. For example, the SNAP PAC device can read the file, add data to it, and send the file—or data from it—to another device on the network.

But one potential problem can cause sending files via FTP to work with some devices, but not others: certain characters in the filename.

Some file systems, like ours on the PAC controllers and brains, allow characters such as colons in filenames. Others, like Windows XP, do not. (You may notice that if you drag and drop a file from a PAC to a Windows PC using Windows Explorer, any colons in the filename are automatically converted to dashes.)

For example, suppose you use the PAC Control command Copy Time to String to name a log file stored on the SNAP PAC device. This command in your PAC Control strategy introduces colons into the filename. If the device you want to send this log file to doesn't accept the colons, you've got a problem.

The solution is simply to replace the colons before sending the file. Here's some sample OptoScript code showing how to easily replace the colons in the filename with more universally accepted underscores. (Remember that the time string is an array that starts at zero.)

Michigan Fish Hatcheries - New Video Case Study

Michigan Fish Hatcheries video case studyGrowing healthy fish in hatcheries requires extensive automation. As Chris Klage says, "You can't freeze a fish, but you can boil 'em real easy."

Chris is a technician at the Wolf Lake hatchery in Michigan. In our latest video case study, he explains why the Michigan Department of Natural Resources trusts Opto 22 systems to automate their six fish hatcheries.

Each of the six hatcheries monitors and controls the power, oxygen, and water needed to produce up to 6 million fish each year for commercial and recreational use.

Upcoming SNAP PAC System Classes in Florida

SNAP PAC SystemIf you're near Fort Lauderdale, Florida, we have a series of useful short classes for you this July, including a two-day introduction to the SNAP PAC System and a morning when you can bring your own equipment and hook it up to the SNAP PAC System.

Most classes include lunch, and some include a $100 or $400 credit toward the purchase of a SNAP PAC Learning Center or a SNAP PAC controller. The Learning Center consists of real hardware and software you can use to explore the SNAP PAC System—and then start your next automation project.

Training is presented by Opto 22 staff and our new distributor for South Florida, Optomize, Inc. Germinal Puigbertrand of Optomize brings nearly 15 years' experience as an Opto 22 Certified Trainer and Distributor to help you with your automation application.

All classes will be held at at the Hyatt Regency Bonaventure Conference Center and Spa, located in Weston/Fort Lauderdale, Florida.
