The RCP file allows you to save custom lists of data associated with a
recipe. Using these files along with the RCP instruction lets you transfer a
data set between the recipe database and a set of user-specified locations
in the controller file system.
The recipe data is stored in Data Log Queue memory.
This section contains the following topics:
• Recipe File and Programming Example on page 428
• Example Queue 0 on page 434
• Example Queue 5 on page 435
• Retrieval Tools on page 442
• Information for Creating Your Own Application on page 443
The following reasons may help you choose which type of memory to
use:
• All the recipe data is stored into the controller's memory module.
Because the recipe data is stored in Data Log Queue memory, it
does not consume user program space.
• If you are not using the data logging function, it allows you more
memory (up to 64K bytes) for RCP files. You can use the Data Log
Queue for data logging and recipe data, but the total cannot exceed
128K bytes.
