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.

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.
