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.

If you've heard about our Opto 22 SNAP PACs with their built-in RESTful API (application program interface), you may be wondering how you'd use that API to send real-world data to the IBM Watson IoT platform.
I'll show you how, step-by-step, in this blog post. It's a long post, but it includes everything you'll want to know. (You can print this page as a PDF if you like.)

OptoForum member tohox recently posted a question about using PID control loops on a SNAP-PAC-R1 rack-mounted controller.
The issue? A really long dead loop time.
"The time delta between the moment the strategy opens a given loop's valve [and] starts the pump+furnace and the moment a temperature increase is measured can sometimes be on the order of an hour," tohox notes.
