Processing details
• This instruction measures the period of time for which the input contact is on in units of hour, and turns on the device
specified by (d2) when the accumulated ON time exceeds the time (32-bit binary data) specified in (s).
• In (s)+1 and (s), specify the period of time until the device specified by (d2) is turned on in units of hour.
• The measured current value in units of hour is stored in (d1)+1 and (d1). ((d1)+1: highest-order, (d1): lowest-order)
• The measured current value of less than one hour (in units of second) is stored in (d1)+2.
• (d2) is set to on when the current value in (d1)+1 and (d1) exceeds the time specified by (s).
• Specify a latched (battery backed) type data register as (d1) so that the current value data can be continuously used even
after the power to CPU module turns off. If a general data type register is used, the current value data is cleared when the
power to the CPU module is turned OFF or when the controller mode switches from STOP to RUN.
• Even after the alarm output specified by (d2) turns ON, the measurement is continued.
• When the current value reaches the maximum value of 32-bit data, the measurement is stopped. For continuing the
measurement, clear the current value stored in (d1) to (d1)+2.
Precautions
• Three devices are occupied by (d1). Make sure that these devices are not used by other machine controls.
