unction Bloc
k Specifications
When function blocks are used, memory is required for the following two items:
1. Function block definitions
2. Instance generation processing when function blocks are pasted into the user program as function
block instances
Therefore, the number of steps used in memory will increase with the number of instances of function
blocks created in the program (item 2).
Creating instances of function blocks (i.e., calling function block definitions and transferring parameters)
uses user program memory.
Function block definitions use memory in the FB Program Area, a special area for function blocks. If the
capacity of the FB Program Area is exceeded, the user program area is used.
