Notes:
The scan time is the time duration for executing one cycle of the user program that is cyclically executed.
The scan time can be checked with special data register D8023 (Scan Time Current Value (ms)).
1. I/O data refresh time of node 0
I/O data refresh time = 8 × 0.68 ms + 5 × 0.08 ms + 4 × 0.29 ms + 2 × 0.58 ms + 2 × 1.09 ms + 18 × 0.08 ms + 28 × 0.29 ms
+ 4 × 0.58 ms + scan time
= 22.22 ms + scan time
2. I/O data refresh time of node 1 and subsequent nodes
I/O data refresh time = 22.22 ms + { 7 × 1.2 ms + 32 × 0.3 ms + 11 × 0.04 ms + 9 × 0.17 ms + 4 × 0.34 ms
+ 7 × 0.08 ms + 19 × 0.29 ms + 0 × 0.58 ms + 5 ms } ÷ 2 + scan time
= 38.42 ms + scan time
