AH500 Programming Manual API 1206 Symbol: D 1 ： Initial device which is reset Bit/Word D 2 ： Final device which is reset Bit/Word Explanation: 1. When the instruction is executed, the values in D 1 ~ D 2 are cleared. 2. When the device number of D 1 is larger than the device number of D 2 , only D 2 is reset. Example: 1. When X0.0 is ON, the auxiliary relays M300~M399 are reset to OFF. 2. When X1.0 is ON, the 16-bit counters C0~C127 are reset. (The values of C0~C127 are cleared to 0, and the contact and the coil are reset to OFF.) 3. When X5.0 is ON, the timers T0~T127 are reset. (The values of T0~T127 are cleared to 0. and the contact and the coil are reset to OFF.) 4.
When X2.0 is ON, the stepping relays S0~S127 are reset to OFF. 5. When X3.0 is ON, the output relays Y0.0~Y1.15 are reset to OFF. 6. When X4.0 is ON, the 32-bit counters HC0~HC63 are reset. (The values of HC0~HC63 are cleared to 0, and the contact and the coil are reset to OFF.) 6-274 Instruction code Operand Function ZRST P D , D 1 2 Resetting the zone Device X Y M S T C HC D L SM SR E PR K 16# “$” DF D 1 D 2 Pulse instruction 16-bit instruction (5 steps) 32-bit instruction AH500 AH500 -
