■ Process progression
When input relay 0000 turns ON, output relay 0500 automatically turns ON for 2 s,
and then 0501 turns ON for 3 s.
Ladder diagram Coding
* The double coil operates normally
across different STP instructions.
➮ Refer to p. 3-114.
Application of ITVL instruction
■ Pulse interval measurement
Measures the pulse interval of input relay 0000 and writes the measured data into
DM0100 (in units of 10 ms).
