List of Operation Execution Times
This appendix describes the operation execution times for each of the function blocks.
How to Calculate the Load Rate
Calculate the load rate based on the following formula. This equation merely serves as a guideline, and the
load rate may differ from the actually measured load rate.
When all operation cycles are the same
Formula: Load rate
sum (ms) of operation execution time of each function block
operation cycle (ms) x
100 + fixed load rate (%)
Note 1
The fixed load rates are as follows:
Operation cycle
Fixed load rate
0.1 s
10%
0.2 s
5%
0.5 s
2%
1 s
1%
2 s
0%
Note 2
The resolution of load rate measurement is 10ms (values lower than 10ms are discarded). The
resolutions of the readout values are as follows for each operation cycle.
Operation cycle
Readout resolution
0.1 s
10%
0.2 s
5%
0.5 s
2%
1 s
1%
2 s
1%
After calculating the total (ms) of "each operation execution time + sequence command execution time",
discard values lower than 10 ms and take the resulting value to be the "sum (ms) of operation execution time
of each function block" in the above equation.
