12.4 DHSCS, DHSCS_I / High Speed Counter Set, High Speed Interrupt Counter Set
6. Priority order in operations among DHSCS, DHSCR and DHSZ instructions for the same
high speed counter when the same comparison value is used.
1) FX3U and FX3UC PLCs
When the same comparison value is used for the same high speed counter in DHSCS, DHSCR and
DHSZ instructions, high speed counter reset (self-reset) by DHSCR instruction is executed with the
highest priority (as shown in the table below).
In this case, the comparison results do not change in DHSCS, DHSCR and DHSZ instructions whose
comparison value is programmed to be the same as the comparison value for self-reset by DHSCR
instruction. To change the comparison results, set the comparison value to "K0".
2) FX
1S, FX1N, FX1NC, FX2N, FX2NC, FX3S, FX3G and FX3GC PLCs
Comparison is executed in the programmed sequence without regard to the instructions.
