(1) During the programmable controller CPU STOP, an analog output test as shown
in Table 3.5 can be performed.
(2) The analog output test performs the following operations in GX Developer device
testing or GX configurator-DA selection testing described in Section 5.6.1.
(a) Set D/A Conversion enable/disable (buffer memory address 0: Un\G0) of the
channel to be tested to enable.
(b) Turn Operating condition setting request (Y9) from OFF to ON. (Refer to
Section 3.3.2)
(c) Sets the output enable/disable flag (Y1 to Y8) for the channel to be tested to
enable (OFF
(d) Writes a digital value equivalent to the analog value to be output in CH
digital value (see Table 3.7 in Section 3.4.1) in the buffer memory.
This function is performed with the D/A converter module of function version
B or later.
Table 3.5 List of analog output test
1 Perform the analog output test after changing the D/A conversion enable/disable setting
(buffer memory address 0: Un\G0) to enable.
POINT
When the digital value storage device has been set in the automatic refresh setting
of GX Configurator-DA, the buffer memory is overwritten since automatic refresh is
performed if the programmable controller CPU is during STOP.
In this case, write a digital value to the digital value storage device instead of the
buffer memory.
