Appendix 3 Buffer Memory Areas
Range setting [Q compatible mode]
When the Q compatible mode function is used, this area is for setting an input range.
■Buffer memory address
The following shows the buffer memory address of this area.
Only the R60AD8-G can use this area.
The input range setting value is the same as the one for the R mode.
The input range cannot be changed for channels with A/D conversion disabled. To change the input range, set the bit
corresponding to the channel of 'A/D conversion enable/disable setting [Q compatible mode]' (Un\G0) to A/D conversion
enable (0), and turn on and off 'Operating condition setting request' (Y9).
■Enabling the setting
Turn on and off 'Operating condition setting request' (Y9).
■Default value
The default value is 4 to 20mA (0H).
