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.

What does the new built-in RESTful API in Opto 22 SNAP PAC S-series and R-series programmable automation controllers mean to you?
It means you can use a variety of programming languages to easily access data in the PAC.

A recent hint shared in the OptoForum reminded us of a super-useful tool in PAC Control that you might not know about: find missing connections.
Say you're moving blocks around or copying and pasting them. Of course you're in a hurry to get it done, and you forget to make new connections with existing blocks.

The PAC Control command "Send Communication Handle Command" is a flexible and useful command to know.
It sends a command that accomplishes a specific purpose for the type of communication handle you're using. For example, you might use it with a File or FTP comm handle to work with files on a SNAP PAC controller.

Here's the latest Code Samples and Tips contribution in our new OptoForum: an example of easier peer-to-peer communication between PAC controllers.
This example takes advantage of the new RESTful API in SNAP PAC hardware controllers (both the standalone S-series and the rack-mounted R-series).

Last OptoNews you heard about all the new features in PAC Project 9.5 and SNAP PAC firmware 9.5, both just released.
The most exciting new features are the HTTP/HTTPS server and RESTful API, giving you secure access to I/O point and variable data in your PAC controller.
These developer- and IoT-ready features are free—all you need to do is update your firmware.
But updating PAC controller firmware on a running system can pose a problem.

I'm extremely excited about the new capabilities of the 9.5 firmware and, in particular, the new RESTful interface (REST API and HTTP/S server) for SNAP PAC controllers. I have several PACs throughout my home for various tasks like lighting, A/C, irrigation, energy management, monitoring, and surveillance. The new RESTful interface allows me to take my home automation system to completely new levels, including interacting with my other home automation/IoT products, like my Nest thermostats, smoke alarms, and NestCams; my Philips Hue lighting; my Wemo switches; and much more.
This post isn’t about home automation, however. It’s about getting the firmware upgrade done and configuring the HTTP/S RESTful server. And in doing so, it was important to me (and my application) that I preserved the persistent control system variables used in my control strategies. So...the following are the steps I took to upgrade my firmware while preserving important data and getting started with REST.
