D/A conversion
enable/disable function
Allows D/A conversion to be enabled or disabled for each channel.
Disabling the D/A conversion for unused channels reduces the conversion
cycles.
D/A output enable/disable
function
Allows the selection of whether to output the D/A conversion value or the
offset value for each channel.
Whether the output is enabled or disabled, the conversion period is
constant.
Range switching function
Allows the output range to be selected for each channel from the following:
• 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
Allows the correction of errors in analog output values.
Analog output
HOLD/CLEAR function
Allows the selection of whether to hold or clear the analog value output
when the CPU module is in the following operating status: RUN, STOP, or
a stop error.
Cyclic data update watch
function
Monitors the update intervals of cyclic data. For the cyclic transmission
stop lasting longer than the specified monitoring time, whether to hold or
clear the last output value can be selected.
Scaling function
Performs scale conversion on a digital value within the range of the scaling
upper limit value and the scaling lower limit value, both of which are set at
desired values. This reduces the time and effort to create a program of the
scale conversion.
Shift function
Provides analog output, adding the set shift value to a digital value. This
function facilitates fine adjustment at the system start-up.
Digital value range check
function
Outputs an error when a digital value is out of the digital input range of the
output range setting.
Alert output function
Outputs an alert when a digital value falls within the alert output range set
in advance.
Trigger output function
Provides D/A conversion in accordance with the input of Trigger output
request.
Trigger output request that is input to the extension input module via an
external device also allows D/A conversion.
CC-Link IE Field Network
synchronous
communication function
Performs D/A conversion with a synchronization period of the master
station that supports the CC-Link IE Field Network synchronous
communication function. This makes it possible to synchronize the
operation with other slave stations sharing the same network.
Error notification function
Notifies an error to the master station by the remote input signal if a
moderate error or a major error occurs in the D/A converter module.
Functions with an
extension I/O module
connected
The main D/A converter module permits the connection of one extension
I/O module.
• With an extension input module connected, remote output signals of the
main D/A converter module can be assigned to remote input signals of
the extension input module connected.
• With an extension output module connected, remote input signals of the
main D/A converter module can be assigned to remote output signals of
the extension output module connected.
Functions unique to an extension I/O module can also be used.
