Range of Input Setup (Address "20, 21")

Range of Input Setup (Address "20, 21")

Buffer Memory Address "20","21"

These are used to set up the range of inputs by channels for an A/D converter module.
To make the setup available, requesting to set up operation condition(Y02) is to be set and reset.
The set values of the channels from 1 to 4 are stored in Buffer Memory Address "20" and the set values of the channels from 5 to 8 are stored in Buffer Memory Address "21".
In case of 4-channel module, Buffer Memory Address "21" is disregarded.
The range of the default values for AD04VI, AD08I is from 4 to 20(mA) and the range for AD08V is from 1 to 5V.
As a set value is stored in EEPROM, the A/D module is operated as previously set value even though the power is on and off.
