Table 3.2 shows the function of the Q62DA-FG.
Table 3.2 Function list
• Specifies whether to enable or disable the D/A conversion for each
channel.
• The conversion speed is 10ms constant despite the number of D/A
conversion enabled channels.
• Specifies whether to output the D/A converted value or output the offset
value for each channel.
• The conversion speed is 10ms constant independently of whether the
output is enabled or disabled.
• The output analog value can be retained when the programmable controller
CPU module is placed in the STOP status or when an error occurs.
• When CH Output enable/disable flag (Y1, Y2) is forced on during
programmable controller CPU STOP, the D/A converted analog value is
output.
• 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.
• A warning is output if a digital input value falls outside the setting range.
• The increment and decrement of the analog output value per conversion
cycle can be restricted.
• When the output range is 4 to 20mA, 4 to 20mA (Extended mode), or user
range setting 1, the output monitor value is watched to detect
disconnection.
• When the range is set to 4 to 20mA (Extended mode), users can choose
the method of setting the disconnection detection value from either
arbitrarily or automatically.
• The module can be changed without the system being stopped.
However, when a user changes modules from an analog output range
extended mode compatible to a non-compatible one, while in analog output
range extended mode setting, an intelligent function module switch error
occurs.
