Inputs to a C200HS-INT01 Interrupt Input Unit (8 inputs/Unit)
Inputs to a CJ1M CPU Unit’s Built-in Inputs (4 inputs/Unit)
Operand Contents
N Specify the Interrupt Input Unit’s unit number.
0: Unit number 0 (interrupt tasks 100 to 115)
1: Unit number 1 (interrupt tasks 116 to 131)

2: Unit number 2 (interrupt tasks 116 to 123)
3: Unit number 3 (interrupt tasks 124 to 131)
D Range: 0000 to 00FF hex
Bits 0 to 7 correspond to each interrupt task. The meaning of the
individual flags is as follows:
0: Interrupt enabled (unmasked).
1: Interrupt disabled (masked).
Operand Contents
N Specify the interrupt input number.
6: Interrupt input 0 (interrupt task 140)
7: Interrupt input 1 (interrupt task 141)
8: Interrupt input 2 (interrupt task 142)
9: Interrupt input 3 (interrupt task 143)
D 0000 hex: Interrupts enabled (unmasked) in direct mode.
0001 hex: Interrupts disabled (masked) in direct mode.
0002 hex: Interrupts enabled for decrementing counter in counter
mode.
