Continuous
execution
32-bit instruction
- - - -
y Flags: None
Operands:
D
1 : Start device of the range to be reset
D
2 : End device of the range to be reset
Explanations:
1. When the instruction is executed, area from D
1
to D
2
will be cleared.
2. 16-bit counter and 32-bit counter cannot use ZRST instruction together.
3. When
D
1
> D
2
, only operands designated by D
2
will be reset.
Program Example:
1. When X0 = On, auxiliary relays M300 ~ M399 will be reset to Off.
2. When X1 = On, 16 counters C0 ~ C127 will all be reset (writing in 0; contact and coil being reset
to Off).
3. When X2 = On, steps S0 ~ S127 will be reset to Off.
4. When X3 = On, data registers D0 ~ D100 will be reset to 0.
5. When X4 = On, 32-bit counters C235 ~ C254 will all be reset. (writing in 0; contact and coil being
reset to Off)
