3.2 Function List
Table3.2 shows the functions of the Q66DA-G.
Table3.2 Function list
Item Function Reference section
D/A conversion enable/
disable function • Specifies whether to enable or disable the D/A conversion for each channel.
• Disabling D/A conversion of unused channels can increase the conversion speed.
Section 3.4.2
D/A output enable/dis-
able function
• Specifies whether to output the D/A converted value or output the offset value for
each channel.
• Regardless of the output enable/disable setting, the conversion speed is "6ms x
number of conversion-enabled channels".
Section 3.3.1
Analog output HOLD/
CLEAR function • The output analog value can be retained when the programmable controller CPU is
placed in the STOP status or when an error occurs.
Section 3.2.1
Analog output test during
programmable controller
CPU STOP
• When CH Output enable/disable flag (Y1 to Y6) is forced on during programmable
controller CPU STOP, the D/A converted analog value is output.
Section 3.2.2
Warning output function • A warning is output if a digital input value falls outside the setting range. Section 3.2.3
Rate control function
• The increase and decrease in analog output values per conversion cycle of one sta-
tion (6ms) can be limited.
• Using this function prevents rapid change of analog output values.
Section 3.2.4
Resolution mode
• The resolution mode can be changed according to the application, and a resolution
setting can be selected from 1/4000, 1/12000 and 1/16000.
• The resolution mode setting is applicable to all channels in block.
• Refer to Section 3.1.1 for the digital input values and maximum resolution in normal
resolution mode and high resolution mode.
Section 3.1.1
Section 4.5
Scaling function
• The input range of digital values can be changed to any given range between -32000
and 32000.
Section 3.2.5
Online module change
• The module can be changed without the system being stopped.
However, if a module in the analog output range extended mode is replaced with a
module that does not support the mode, an intelligent function module switch error
occurs.
