8 APPLICATION INSTRUCTION
8.17 Pulse Related Instruction
Measuring the density of 32 bit binary pulses
DSPD
This instruction counts the number of times the device input specified by (s1) turns off
on only for the time (in 32-bit data
units) specified by (s2)
1ms and stores the operation result in the device specified by (d). The high-speed pulse input/output
module is not supported.

Applicable devices
*1 When a bit device is specified, specify one of X0 to X17.
Only X can be used for a bit device.
The nibble of a bit device cannot be specified.
*2 When a word device is specified, specify one of the channel numbers (CH1 to CH8).
When FX3 compatible function of a high-speed counter is valid, a channel number cannot be specified. Only X can be used for a bit
device.
If the channel numbers is specified in (s1), an error occurs.
