3.2.2
Analog output test during programmable controller CPU STOP
(1) While the programmable controller CPU is in STOP, an analog output test as shown in
Table3.4 can be performed.
(2) To conduct an analog output test, perform the following on Device test of GX Devel-
oper or on the relevant test screens of Configurator-DA (Refer to Section 5.6.1.).
(a) Set D/A conversion enable/disable setting (Un\G0) of the channel to be tested to
enable.
(b) Turn on Operating condition setting request (Y9).
(c) Check that Operating condition setting completed flag (X9) has turned off. Then
turn off Operating condition setting request (Y9).
(d) Sets CH Output enable/disable flag (Y1 to Y6) for the channel to be tested to
enable (off on).
(e) Write digital values equivalent to analog values that are to be output to CH Digi-
tal value (Un\G1 to Un\G6).
*1 Perform the analog output test after changing D/A conversion enable/disable setting (Un\G0) to
enable.
When the digital input value is set to be written to CH Digital value (Un\G1 to
Un\G6) from the CPU device at the automatic refresh setting of GX Configurator-
DA, write digital input value to the CPU device where the setting is performed. The
automatic refresh can be performed while the programmable controller CPU is in
STOP.
