Table 3.2 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.
• The conversion speed is 10ms regardless of the number of conversion
enabled channels.
Section 3.4.2
D/A output
enable/disable function
• Specifies whether to output the D/A converted value or the offset value for
each channel.
• The conversion speed is 10ms constant independently of whether the
output is enabled or disabled.
Section 3.3.1
Analog output
HOLD/CLEAR function
• The output analog value can be retained when the PLC CPU module is
placed in the STOP status or when an error occurs.
Section 3.2.1
Analog output test
during PLC CPU STOP
• When the CH
output enable/disable flag is forced ON during PLC CPU
STOP, the D/A converted analog value is output.
Section 3.2.2
Output monitor function
• The analog output value output by D/A conversion is reconverted into a
digital value within the Q62DA-FG and the result is stored into the buffer
memory as an output monitor value.
Section 3.2.3
Warning output function
• A warning is output if a digital input value falls outside the setting range.
Section 3.2.4
Rate control function
• The increment and decrement of the analog output value per conversion
cycle can be restricted.
Section 3.2.5
Disconnection detection
function
• When the output range is 4 to 20mA or user range setting 1, the output
monitor value is watched to detect disconnection.
Section 3.2.6
Online module change
• The module can be changed without the system being stopped.
