22: DUAL / TEACHING TIMER INSTRUCTIONS
Introduction
Dual timer instructions generate ON/OFF pulses of required durations from a designated output, internal relay, or shift
register bit. Four dual timers are available and the ON/OFF duration can be selected from 1 ms up to 65535 sec.
Teaching timer instruction measures the ON duration of the start input for the teaching timer instruction and stores the
measured data to a designated data register, which can be used as a preset value for a timer instruction.
DTML (1-sec Dual Timer)
DTIM (100-ms Dual Timer)
DTMH (10-ms Dual Timer)
DTMS (1-ms Dual Timer)
