Scan Completed 
*1 When "Level" is selected for "Detection Method", the level condition of the specified device is checked for each link scan of the set
RJ71LP21-25 and an interrupt occurs. Therefore, if the sequence scan takes much longer than the link scan, sequence scan time may
greatly increase, resulting in the WDT time being exceeded in the CPU module.
When "Detection Method" is set to "Level" and the interrupt condition is always met, do not use interrupt settings and check the condition
in the program.
*2 When "Scan Completed" is selected, an interrupt occurs for each link scan of the set RJ71LP21-25.
• Using an interrupt program will eliminate the need for describing a start condition in a program. This leads to
reduction in the number of steps and sequence scan time.
A changed value in the device cannot be detected if the changed value is shorter than the transmission delay
time.
When an interrupt program is executed, link refresh is not performed between the CPU module device and
link device. Use the direct access function to access the link device when an interrupt program is being
executed.

Detection Method Condition Type
• Level + ON: Interrupt occurs by turning on the device.
• Level + OFF: Interrupt occurs by turning off the device.
• Edge + ON: Interrupt occurs at the rising edge of the
device.
• Edge + OFF: Interrupt occurs at the falling edge of the
device.
• Level + Values Match: Interrupt occurs when values
match.
• Level + Values Mismatch: Interrupt occurs when values
do not match.
• Edge + Values Match: Interrupt occurs when values
match (first time only).
• Edge + Values Mismatch: Interrupt occurs when values
do not match (first time only).
