Cam Switch
The preset output status of the coincidence output range is compared with a count value to switch on or off the output of the
multi function counter block at each step.
The following is an example assuming that an output is switched by seven steps as follows. Note that this link example is for
when a 32-bit unsigned multi function counter block is used. (The cam switch is not supported by 16-bit multi function counter
blocks.)
Link and parameter
The following shows a link example of the hardware logic outline window and a link example and parameter setting example
of the multi function counter block detail window.
