Did you miss any of these technical tips?

Now's a good time to review some automation basics—and look ahead to new technologies in our field.

Accuracy and resolution. Specifications for both of these are included for our analog modules. What's the difference?

Sinking and sourcing. What do these terms mean when you're wiring digital DC outputs, and which is the better way to wire? Lots of questions and answers on this one.

• Think about how much computers have changed in the last 30 years.
• Think about the quantity of data that enterprise data centers (EDCs) process today.
• And think about how facility management priorities have changed to meet rising energy costs.

Now imagine what needs to be done to update a 30-year-old EDC.

In the last OptoNews, we showed you how an Excel^® spreadsheet can exchange data with an Opto 22 SNAP PAC using the SNAP PAC controllers' RESTful API (application programming interface).

This time we'll show you how you can use the REST API with a Microsoft^® Access^® database.

When you're troubleshooting system problems, PAC Manager can be a big help. That's because PAC Manager communicates directly with your controllers and I/O units.

You're probably already familiar with PAC Manager's Inspect window, where you can see detailed status data on an I/O unit or controller. This tip shows you a way to create your own custom checks on anything in the Inspect window.
