(2) Terminals for the pulse measurement
The following table lists the terminals that are used for the pulse measurement for each channel.
Channel
CH1
CH2
(3) Pulse width to be measured
Set which pulse width (ON or OFF) is to be measured by using "CH Pulse measurement setting (Function input
terminal)" and "CH Pulse measurement setting (Latch counter input terminal)".
The measured value is stored in CH Measured pulse value (Function input terminal) (RWr1C to RWr1D, RWr34
to RWr35) or CH Measured pulse value (Latch counter input terminal) (RWr1E to RWr1F, RWr36 to RWr37).

Pulse ON width
Pulse OFF width
(4) Measurable range of the pulses
The measurable range of the pulses is between 2000 and 2147483647 (0.2ms to approx. 214s). When the input
pulses are beyond the measurable range, the error code (660
(RWr22, RWr3A) and Error status flag (RXA) and the ERR. LED turns on.
To resume the measurement, input the pulses once again, or perform the operation as shown below.

*1 The abbreviations mean as the follows.
• F start command: CH Pulse measurement start command (Function input terminal) (RY30, RY48)
• L start command: CH Pulse measurement start command (Latch counter input terminal) (RY32, RY4A)
• F measurement flag: CH Pulse measurement flag (Function input terminal) (RWr20.b6, RWr38.b6)
• L measurement flag: CH Pulse measurement flag (Latch counter input terminal) (RWr20.b7, RWr38.b7)
(5) Update timing of the measured values of pulses
The measured pulse value is updated in the remote register every ΔT
twice or more within ΔT
refer to the following.
