Control Engineering's recent webcast, Engineering with Ethernet, explored Ethernet protocols, managed and unmanaged network switches, network architecture options, Power over Ethernet, Ethernet's role in Intelligent Safety Networks, IGMP snooping, and the use of wired and wireless Ethernet.
Now the webcast is archived on Control Engineering's website. Listen and watch as David Greenfield interviews Opto 22's Benson Hougland, Michael Frayne from Molex, and Wayne Nicholson from N-Tron.

We've got analog, digital, and serial I/O modules for just about any signal you need.
But how do you find the right module?
Here's an easy online way: the SNAP I/O Selector.
This great tool on our website lets you start by choosing the signal type. Then pick the number of channels and whether you need inputs or outputs.
Click the part number to see description and wiring, and then go straight to the product page.

When you're working with multiple SNAP PAC controllers, PAC Terminal utility software can save you a lot of time. Today's tip from the Opto 22 Product Support Group (PSG) shows you a quick way to get basic and detailed controller status data for all your controllers.
PAC Terminal is installed with any version of PAC Project.
To open PAC Terminal, choose Start > Programs > Opto 22 > PAC Project > Tools > PAC Terminal.
The main PAC Terminal window shows you all controllers' names and IP addresses.
- For a quick summary of all controllers, click Scan All on the right side of the window.
- Or highlight the controllers you're interested in and click Scan Selected.
Brief status messages appear in the Status column in the main window. Uh-oh, one of these has a stopped strategy:
For detailed information, double-click a controller's name in the list to open its Inspect window. You can open multiple Inspect windows to compare several controllers:
The inspect window shows a lot of information:
- The controller and its IP address
- Firmware version
- RAM available
- How long it's been turned on
- Date and time on the device (Click Sync time to PC to make sure the controller and the PC show the same time.)
- Number of messages in the message queue (Click the blue number to open the message queue.)
- Data on active and alternate strategies (An alternate strategy appears if you're using background downloading. You can use this section of the window to manually run or stop the strategy, switch strategies, and store either or both to flash memory.)
- Communication loop time and communication errors
