AH500 Programming Manual API 0401 Symbol: S ： Jump destination Explanation: 1. The execution of the program jumps to the part of the program specified by the pointer without any condition. 2. If the program specified by the label is prior to the instruction JMP, the watchdog timer error will occur, and the PLC will stop running. Please use the instruction carefully. 3. When the instruction is executed, the actions of the devices are as follows. The state of Y, the state of M, and the state of S remain the same as those before the execution of the jump. The timer stops counting.
If the instruction which is used to reset the timer is driven before the jump is executed, the timer will still be in the condition of being reset during the execution of the jump. The general applied instructions are not executed. 6-142 Instruction code Operand Function JMP S Unconditional jump Device X Y M S T C HC D L SM SR E PR K 16# “$” DF S Pulse instruction 16-bit instruction (3 steps) 32-bit instruction － AH500 －
