4. Instruction Execution Times and Number of Steps
Note The number of instruction steps in the function block definition (p) will
not be diminished in subsequence instances when the same function
block definition is copied to multiple locations (i.e., for multiple in-
stances). Therefore, in the above equation, the number of instances
is not multiplied by the number of instruction steps in the function
block definition (p).

m Call part
n I/O parameter 1-bit (BOOL) input symbol
transfer part or output symbol
The data type is
1-word (INT, UINT,
shown in parenthe-
WORD) input symbol or
ses.
output symbol
2-word (DINT, UDINT,
DWORD, REAL) input
symbol or output symbol
4-word (LINT, ULINT,
LWORD, LREAL) input
symbol or output symbol
I/O symbols
p Number of instruc- The total number of instruction steps (same as standard
tion steps in func- user program) + 27 steps.
tion block definition
Example:
Input variables with a 1-word data type (INT): 5
Output variables with a 1-word data type (INT): 5
Function block definition section: 100 steps
Number of steps for 1 instance = 57 + (5 + 5)
= 244 steps
