8-5 Recipes
8-5-1 Overview
A model’s set values can be written or read to the specified PLC addresses for
a command from the PLC or PT.
A model’s (block’s) set values can be saved in the PT as a table called a rec-
ipe file. The recipe file number and block number (model number) can be
specified in the control address area of the specified PLC to execute read/
write operations. Set values for each model can be read or written simply by
changing the block number (or model number).
A recipe table is made from maximum of 100 blocks and 100 set values. Rec-
ipe files are specified by their numbers. Up to 100 recipe files (No. 0 to 99) can
be stored.
8-5-2 Controlling Recipes
The recipe function allocates 4-word control addresses in the PLC memory.
Recipes are controlled from these words. Turn ON word n bit 0 (write) or bit 1
(read) after specifying the file number in word n+1 and the block number in
word n+2 in the control words to read or write recipes.

Additional Information
• The total quantity of recipes that can be saved in the PT is approximately 3,600
words. However, it may be less depending on the number of files and whether
there are comments.
• The amount of memory that can be used as recipes can be checked in the
Resource Report under the Tool Menu of the NV-Designer.
Precaution for Correct Operation
• Do not use the SPMA function when the recipe function is operating.
• Data may be corrupted if there is a power interruption while the recipe data is
being updated.
• Recipe data can be read from the PLC to the PT or deleted approximately
100,000 times.
