Averaging Time

If the averaging time is set for the PNK-ADP, the averaged temperature measurement data will be stored in
the D8260 to D8263, D8270 to D8273, D8280 to D8283, and D8290 to D8293. The averaging time can be set
for each channel.
Set the averaging time in the following special data registers:

1. Cautions regarding averaging time setting
• If the averaging time is set to "1", the immediate data will be stored in the temperature measurement
special data register.
• If the averaging time is set to "2" or more, the average value will be calculated in accordance with the set
averaging time, and the average value obtained will be stored in the temperature measurement special
data register.
• After turning the PLC power on, the average data will be stored in the temperature measurement special
data registers (D8260 to D8263, D8270 to D8273, D8280 to D8283, and D8290 to D8293) until the number
of data items is increased to the set averaging time.
• Set the averaging time in the range from 1 to 4095. If the set value is outside the setting range, the error
signal will be output.
