Reference: Recipe elements differ from numeral display and numeral input elements in the

When setting parameters from the PT, you must make settings by combined
use of numerical input and the confirmation touch switches on the base screen
or pop-up window.
If there is a numerical input column in the pop-up window, it is a temporary
input column. Once input values are displayed in the temporary input col-
umn, press the Return key to store them to the parameters column.
Record data (parameters) for recipe data can be transmitted to/from words in
the host.
Record data (parameters) for recipe data cannot be read/written directly from/
to the numeral memory table. Consequently, to display record data set in the
PT as graphs or numeral display elements, perform the following operation.
1. Write the record data (parameters) to words on the host.
2. Specify the recipe data write address to the area allocated in the host for
numeral memory table entries.
3. Refer to the numeral memory table entries in step 2 using graphs or numeral
display elements.
Recipes will be stacked in order of the elements registered on screen using the
Support Tool. (Only one recipe can be created in one screen, so the order of
recipes may not be changed. You also cannot change the display order be-
tween recipes and other elements.)
following ways:
S Recipe elements hold recipe data separately from memory table entries within
the PT. Recipe data is read and written in record units to and from a consecu-
tive area in the host starting from a specified word.
S You can read and write data not merely for one word, but for multiple words
(200 records maximum, 400 words maximum) in a single operation.
S You can collate the data from these multiple words as a single record, and set
and display up to a maximum of 1,000 recipe data records in table format.
S The direction of data transfer with the host as either from PT to host, or from
host to PT, is selected using the touch switches.
S The execution and timing of data transfer with the host is controlled by touch
switch operation (i.e., using the Write touch switch or Read touch switch). (Un-
like numeral display elements, data is not always read from the host).
