On Pulse Catch Input Function
The I/O mixed unit (FP2
−
XY64D7T/FP2
−
XY64D7P) is equipped with “On pulse catch
input” function. The on pulse catch input function has a delay circuit built into the input
and is used in combination with a periodical interrupt function to make possible the read-
ing of on pulses with extremely small widths.
Readable pulse signals
Minimum pulse width: 0.4ms
Pulse interval: 6ms or more
Pulse interval: 6ms or more
Min. pulse width :
0.4ms
Method
In the program, specify the interval of periodical interrupt and the word number of I/O.
Considerations
The interval for the periodical interrupt is determined by the interrupt control instruction.
Specify the pulse catch I/O (input) with the
ICTL
and
F143 (IORF)
instructions.
Program example
When an I/O mixed unit with on pulse catch input function is installed to slot “0” of the
backplane.
Specifying the interval for the periodical interrupt
(set to 1ms)
Interrupt program
Specifying the word number of I/O for I/O update
