Averaging Time

If the averaging time is set for the 2AD-BD, the average data will be stored as the input data. The averaging
time can be set for each channel.
Set the averaging time in the following special data registers:
Special data register
1st board
D8264
D8265
1. Cautions regarding averaging time setting
• If the averaging time is set to "1", the immediate data is stored to the special data register.
• If the averaging time is set in the range from 2 to 4095, the average value will be calculated to conform to
the set averaging time, and the average value obtained will be stored in the special data register.
• After turning the PLC power on, the current data is stored to special data registers until the number of data
items reaches the set averaging time. After this, the average data will be stored.
• Set the averaging time in the range from 1 to 4095. If the set value is outside the setting range, an error
signal will be output.
