Number of Function Block Program Steps and Instance Execution Time
Operation
A Startup time
B I/O parameter trans-
fer processing time
The data type is
indicated in paren-
theses.
C Function block defi-
nition instruction
execution time
Note
78
The following table shows the length of time for A, B, and C.
Startup time not including
I/O parameter transfer
1-bit input variable, out-
put variable, or input-out-
put variable (BOOL)
1-word input variable,
output variable, or input-
output variable (INT,
UINT, WORD)
2-word input variable,
output variable, or input-
output variable (DINT,
UDINT, DWORD, REAL)
4-word input variable,
output variable, or input-
output variable (LINT,
ULINT, LWORD, LREAL)
Total instruction processing time (same as standard user program)
Example: CJ1H-CPU67H-R
Input variables with a 1-word data type (INT): 3
Output variables with a 1-word data type (INT): 2
Total instruction processing time in function block definition section: 10 µs
Execution time for 1 instance = 3.3 µs + (3 + 2) × 0.19 µs + 10 µs = 14.25 µs
The execution time is increased according to the number of multiple instances
when the same function block definition has been copied to multiple locations.
