Chapter 6 Applied Instructions Symbol S ： Data source Explanation 1. The data source S can contain only decimal numbers, and the number must be an interrupt number. If the number in S is not an interrupt number, the instruction is not executed and no warning is shown. For example, use DIX500 when you want to disable the I500 interrupt. Refer to the interrupt number list in the explanation of the EI instruction. 2. The default for interrupt tasks in the ES3 Series is enabled. Use the DIX instruction to disable the interrupts. 6_ 3. You can use this instruction to disable the interrupt tasks in SR623–SR634. 4.
If this instruction is not executed, then the contents of SR623–SR634 determine whether an interrupt task is performed or not. 5. Refer to the examples for the EI instruction (API 0501) for more information. 6-169 API Instruction code Operand Function 0504 DIX S Disabling a specific interrupt Device X Y M S T C HC D FR SM SR E K 16# “$” F S BOOL WORD DWORD LWORD UINT INT DINT LINT REAL LREAL TMR CNT STRING Data type S Pulse instruction 16-bit instruction 32-bit instruction － ES3 －
