6.8 Examples of Wiring for Various Uses
Interruption
Examples of wiring for when the input interruption function of the CPU module is used are shown below.
The same wiring is used for the pulse catch and pulse width measurement functions.
When capturing pulses of a response frequency of 50 to 200 kHz, refer to Page 86 In the case of capturing high-speed
pulses.
For details on the input interruption function, pulse catch function and pulse width measurement function, refer to
MELSEC iQ-F FX5 User's Manual (Application).
