MELSEC iQ-R Digital-Analog Converter Module User's Manual (Application)
*1 This function is supported only by the R60DA4 and R60DAI8.
*2 The firmware update function cannot be used for the module in offset/gain setting mode.
Precautions
Check that output from the D/A converter module is stopped before performing the firmware update function. Performing the
firmware update function without stopping the output may cause unintended operation of the module, resulting in failure of the
system.
Item Description
Range switching function Switches the output range of the analog outputs for each channel. Switching the range makes it possible to
change the output conversion characteristics.
D/A conversion enable/disable setting function Controls whether to enable or disable the D/A conversion for each channel. Disabling the D/A conversion
on unused channels reduces the D/A conversion cycles.
D/A output enable/disable setting function Specifies whether to output the D/A conversion value or offset value for each channel. The conversion
speed is a constant, regardless of the output enable/disable status.
Analog output HOLD/CLEAR function Sets whether to hold or clear the analog output value output when the operating status of the CPU module
is RUN, STOP, or stop error.
Analog output test function when the CPU
module is in the STOP status Analog output tests can be carried out when the CPU module is in the STOP status.
Scaling function Performs scale conversion on digital values within a specified range between a scaling upper limit value
and a scaling lower limit value. The program for scale conversion can be omitted.
Shift function Adds a set input value shift amount to a digital value.
Alert output function Outputs an alert when the digital value exceeds the alert output upper limit value or becomes less than the
alert output lower limit value.
Rate control function Restricts the increasing/decreasing amount of the analog output value per 80

s and prevents a sudden
change of the value.
Interruption of external power supply detection
function Detects that the external power supply 24VDC is not supplied or is shut off.
Disconnection detection function
*1
Monitors the analog output value and detects a disconnection.
Interrupt function Executes an interrupt program of the CPU module when an interrupt factor such as a disconnection or an
alert output is detected.
Wave output function Registers the prepared wave data (digital input value) to the D/A converter module and continuously
outputs the data (analog value) in the set conversion cycle.
Inter-module synchronization function Outputs the D/A conversion values simultaneously from multiple modules in which the inter-module
synchronization function is active.
Error history function Records up to the 16 errors and alarms that occurred in the D/A converter module to store them into the
buffer memory area.
Event history function Collects occurred errors and alarms, and performed operations in the D/A converter module as event
information into the CPU module.
Offset/gain setting Corrects errors in D/A conversion values for each channel.
Backing up, saving, and restoring offset/gain
values Makes it possible to back up, save, and restore the offset/gain values of the user range setting.
Online module change Allows module replacement without stopping the system. For the procedure of the online module change,
refer to the following.

Q compatible mode function Controls an operation state with the buffer memory layout converted to equivalent one of the Q series. This
compatibility makes it possible to reuse sequence programs that have exhibited high performance on the Q
series analog output modules.
Firmware update function
*2
Enables users to update the firmware versions of modules by using firmware update files. (For the firmware
update file, please consult your local Mitsubishi representative.) For details on this function, refer to the
following.
