9.1 Calculation of Recipe Size
To calculate how much space a recipe requires in the project memory, the following
equation is used. (The equation is not exact in view of the file systems complexity in
the operator panel.)
S = 90 + Σ (2 ∗ IOG
i
+ 28)
S = number of bytes. If S is calculated to be less than 360, then S is set to 360.
Σ = number of I/O series.
IOG
i
= number of I/O in each I/O series
Example
The recipe consists of 3 I/O series: D0-D109 (110), D200-D499 (300) and M0-
M99 (100).
The calculation is made i two steps.
1. Calculate the subtotals of the different series:
1104 = (2 * 110 + 28) + (2 * 300 + 28) + (2 * 100 + 28)
2. Then calculate the total:
S = 90 + 1104
S = 1194 bytes
Note:
The maximum number of I/Os in a recipe is 1000.
