Pulse Outputs Section 7-6
Set the pulse output operation mode to 1 shot in advance in the System
Setup, as shown in the following table.
Note A pulse output port that is being used for one-shot pulse outputs cannot be
used for any other pulse output functions.
The elapsed time of the one-shot pulse output is stored in 8-digit hexadecimal
in words A621 and A620 (pulse output 1) or A623 and A622 (pulse output 2).
When the one-shot pulse output is turned ON, the content of the correspond-
ing words is set to 0000 0000 hex and the content is incremented as time
passes. The final value is retained when the one-shot output is turned OFF.

Setup.
2. Execute the STIM(980) instruction with operand C1 = #0001
or #0002.
Response time Response time when the STIM(980) instruction is executed at
the beginning of an interrupt task:
