Chapter 6 Applied Instructions API 2401 Symbol: S ： Task number Word Explanation: 1. The cyclic task specified by S is disabled. 2. When the PLC runs, the execution of the cyclic tasks depends on the setting of the cyclic tasks in ISPSoft. 3. The description of the operands: The operand S should be within the range between 0 and 31. Please refer to ISPSoft User Manual for more information about creating and enabling the tasks. Example: When the PLC runs, cyclic task (0) and cyclic task (1) are enabled. Since the instruction TKOOFF in cyclic task (0) is executed, cyclic task (1) is disabled, and Y0.0 is OFF. The two cyclic tasks are created in ISPSoft.
Cyclic task (0) and cyclic task (1) are enabled when the PLC runs, and cyclic task (1) is disabled when the instruction TKOFF in cyclic task (0) is executed. Cyclic task (1) is disabled by the execution of the instruction TKOFF in cyclic task (0). Cyclic task (1) is not executed. Additional remark: Please refer to ISPSoft User Manual for more information related to tasks. 6-541 Instruction code Operand Function TKOFF P S Disabling the cyclic task Device X Y M S T C HC D L SM SR E K 16# “$” DF S Pulse instruction 16-bit instruction (3 steps) 32-bit instruction AH500 AH500 -
