Reference
D/A conversion enable/disable function
Whether to enable or disable D/A conversion can be set for each channel.
Disabling the D/A conversion for unused channels reduces the
conversion cycles.
D/A output enable/disable function
Whether to output the D/A conversion value or the offset value can be set
for each channel.
The conversion speed is constant, regardless of the output
enable/disable status.
Range switching function
The output range can be selected for each channel from the following
ranges:
• Factory default range (4 to 20mA, 0 to 20mA, 1 to 5V, 0 to 5V, -10 to
10V)
• User range (user range setting 1, user range setting 2)
Offset/gain setting function
This function compensates for errors in analog output values.
Analog output HOLD/CLEAR function
Whether to hold or clear the output analog value can be set, according to
the CPU module operating status (RUN, STOP, or stop error).
Cyclic data update watch function
The update intervals of cyclic data are monitored. The last output value is
held or cleared when the cyclic transmission stop status continues longer
than the set monitoring time.
Scaling function
The D/A converter module scale-converts the digital value to the set
range of the scaling upper limit value and scaling lower limit value. The
programming for scale conversion can be reduced.
Shift function
Using this function, the D/A converter module outputs the converted
digital value with the shifting set value added, in analog. Fine adjustment
can be performed easily when the system starts.
Digital value range check function
An error is output when the digital value is out of the digital input range for
the output range.
Alert output function
This function outputs alert when a digital value is in the range set in
advance.
Error notification function
When a moderate error or major error occurs in the D/A converter
module, this function notifies the master station of the error with the
remote input signal.
Function at the extension module installation
One extension I/O module can be connected to one D/A converter
module.
Remote input signals of the D/A converter module can be assigned to
remote output signals of the connected extension output module. In
addition, functions unique to the extension I/O module can be used.
CC-Link IE Field Network diagnostic function
With this function, whether any network error occurs or not can be
checked through GX Works2 connected to the CPU module.
