CNT24-4D(PCI)H
Programmable Timer
The programmable timer can generate interrupts at cycles according to a 32-bit setting data. The timer
can be set in a range of 1msec through 200sec.
One-shot Pulse
When the count value of a channel matches a preset compare value, this channel will generate a one-shot
pulse. The width of this pulse is the same for all channels and is determined by set data. The width can
be set in a range of 0 through 104.45msec.
CAUTION
- The default state is set to "pulse width=0 (do not output).
- Pulse widths may slightly vary depending on the specifications of a connected load.
General-purpose Input Signal Select
This command selects line receiver input or TTL-level input for the general-purpose input signals of a
corresponding channel when line receiver input is in use.
CAUTION
- The initial state is set to "line-receiver input (00H)."
- The line receiver input cannot be select for the general-purpose input signals when the TTL level
input is used. Only TTL-level input is available.
