Operands:
D
1
: Start device of the range to be reset
D
2
: End device of the range to be reset
Explanations:
1.
No. of operand D
1
≤
No. of operand D
2
.
2. D
1
and D
2
have to designate devices of the same type.
3.
ES/EX/SS series MPU does not support E, F index register modification.
4.
See the specifications of each model for their range of use.
5.
When the instruction is executed, area from
D
1
to
D
2
will be cleared.
6.
In ES/EX/SS, 16-bit counter and 32-bit counter cannot use ZRST instruction together.
7.
In SA/EH, 16-bit counter and 32-bit counter can use ZRST instruction together.
8. 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 X10 = On, timers T0 ~ T127 will all be reset (writing in 0; contact and coil being reset to Off).
4.
When X2 = On, steps S0 ~ S127 will be reset to Off.
5.
When X3 = On, data registers D0 ~ D100 will be reset to 0.
6.
When X4 = On, 32-bit counters C235 ~ C254 will all be reset. (writing in 0; contact and coil being reset to Off)

Remarks:
1.
Devices, e.g. bit devices Y, M, S and word devices T, C, D, can use RST instruction.
2.
API 16 FMOV instruction is also to send K0 to word devices T, C, D or bit registers KnY, KnM, KnS for reset.
