Recipe management
The following formula is used for determining the recipe size in the project memory. (The
formula does not always provide exact results due to the complexity of the file system).
S = 90 + ?(IOGi + 28)
S = Number of bytes. If the calculated value S is smaller than 360, the value 360 must
be assumed for S.
? = Number of I/O series
IOGi = Number of I/Os in each I/O series
Example
Our recipe consists of three I/O series H0-H109 (=110 double words) and H200-H299
(=100 double words).
This results in the following calculation:
Calculating the various series sums:
896 = (4 * 110 + 28) + (4 * 100 + 28)
This results in the following sum:
S = 90 + 896
S = 986 bytes
Under [Setup] / [Recipe settings], you define the settings for recipe handling and create,
edit and delete recipe directories.
Control block for saving, reading, and deleting recipes via controller.
See section "Creating and transferring recipes using the controller program" on page
190.
Enter the first of four 16-bit registers where the terminal stores the name of the recipe
that was last loaded to the controller. This name can then be represented as ASCII
object. The function occupies all four registers (8 characters) disregarding the length of
the recipe name.
Enable directories Selecting this option enables you to create recipe directories in the terminal.
See section "Recipe directory" on page 188.
