Y1 to Y8
CH output
enable/disable flag
(1) Specifies whether to output the D/A converted value or offset value for each
channel.
ON: D/A converted value OFF: Offset value
(2) The D/A conversion speed is constant regardless of whether the output
enable/disable flag is ON or OFF.
Y9
Operating
condition setting
request
(1) This turns ON when the contents of the D/A conversion enable/disable setting are
validated.
(2) See the X9 column for the ON/OFF timing.
YA
User range write
request
(1) This turns ON when the values for the adjusted offset/gain settings are registered in
the D/A conversion module.
(2) See the XA column for ON/OFF timing.
See Section 4.6 for offset/gain settings.
YB
Channel change
request
(1) This turns ON when changing the channel for which offset/gain settings are to be
performed.
(2) See the XB column for the ON/OFF timing.
YC
Set value change
request
(1) This turns ON/OFF when increasing or decreasing the analog output value during
adjustment of the offset/gain settings.
(2) The analog output is either increased or decreased based on the value that was set
in buffer memory address 24 (Un\G24).
YD
Synchronous
output request
(1) While in the synchronous output mode, D/A conversion is performed and the analog
value is output at the timing when the synchronous output request (YD) is set to
