Pulse Measurement Mode

This section describes settings and functions that become valid when "Pulse Measurement Mode" is selected for
"Operation Mode Setting". In this mode, the on or off width of pulses that are input to Function input signal is
measured. The measured pulse value is written to the specified device using the Measured pulse value read
instruction (ICPLSRD1(P)) ( Page 254, Section 8.10.1 (9)). The following table shows I/O signals used in this
mode.

*1 The signals can be used for other functions such as the general-purpose input except the interrupt input.
*2 The signals can be used for other functions such as the general-purpose input and output.
Note that the explanations in this section assume use of CH1. For the special relay, special register, dedicated
instructions, and error codes for CH2, refer to the following.
