ISPSoft User Manual The Task Type section for a DVP-SV series PLC is shown below. If users want to set a task corresponding to the interrupt I001, they have to select External Interruption (X0) in the Task Type section first. (I001 is triggered when the signal passing through X0 goes from low to high.) The description of External Interruption (X0) will be displayed in the Task Description section. According to the message in the Task Description section, I001 is rising edge-triggered if the value in the External box is 1. As a result, the users have to select 1 in the External box. Example 2: The figure below is the Task Manager window for AHCPU530-EN. The task selected is Cyclic (1) .
Owing to the fact that users can enable and disable a cyclic task in an AH500 series CPU module through the applied instructions TKON and TKOFF, they can set the initial state of the cyclic task. If the Active checkbox is unselected, Cyclic (1) is disabled when the program is TKON to enable Cyclic (1) . Please refer to AH500 Programming Manual for more information executed. Cyclic (1) is not enabled until a POU assigned to another task uses the instruction about TKON and TKOFF. Example 3: The figure below is the Task Manager window for AHCPU530-EN. The task selected is I/O Interruption (2) .
Owning to the fact that users can set the condition of an I/O interrupt by themselves, the message in the Task Description section indicates that the condition of I/O Interruption (2) can be set in HWCONFIG. The setting of the condition of I/O Interruption (2) in HWCONFIG is described below. 5-32
