6 Application Instructions API 00-49 API 40 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. 7. In SA/EH, 16-bit counter and 32-bit counter can use ZRST instruction together. 6. In ES/EX/SS, 16-bit counter and 32-bit counter cannot 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.
