VS070QS-1618MDM1 Integrated Machine High-speed counter
202403 (V1.0) 35
B.3.2 1PH counting up/down input high-speed counter
Features: A counter starts to count only when the pulse input changes from OFF to
ON, and the count direction is determined by two input points. The state of the
high-speed counter is determined by its corresponding special auxiliary relay (SM
element), and an action example is shown as follows.
The time sequence chart of the contact actions in the program is shown in the
following figure.
When X11 and X7 are ON, X5 is ON,
C250 is cleared, and the contact is
reset.
Note:
1. Counter input points: X3 and X4.
2. High-speed counters, when used in DHSCS, DHSCR, DHSZ, DHSP, and DHST commands, can trigger operations or
controls free from the scan cycle.
When X4 changes from OFF to ON,
C250 counts down; SM250 is ON.
When the count value of C250 reaches 3,
state of C250 contact changes.
When X11 and X7 are ON, C250 starts to count.
When X3 changes from OFF to ON, SM250 counts up; SM250 is
OFF.
When X10 is ON, C250 is reset regardless of X11 and X7.
