• When Start request (1) is set in 'Trigger start request' (Un\G120) before a trigger condition is set, a trigger
start error at trigger setting disabled (error code: 10C0H) occurs.
• When the hardware logic control is stopped in the trigger ready, the trigger status is switched to the trigger
stop.
• When Start request (1) is set in 'Trigger start request' (Un\G120) during simulation, a trigger start error
during simulation execution (error code: 10C1H) occurs. In addition, the trigger status is not switched to the
trigger ready.
■Sampling data acquisition completion
When the trigger condition is satisfied while Trigger ready (1) is stored in 'Trigger status monitor' (Un\G123), sampling data is
generated according to the trigger setting. Trigger stop (0) is stored in 'Trigger status monitor' (Un\G123) and Sampling data is
acquired (1) is stored in 'Sampling data acquired flag' (Un\G124).
Sampling data can be read only when Sampling data is acquired (1) is stored in 'Sampling data acquired flag' (Un\G124).
Sampling data generated before the trigger start is discarded by a trigger start request or execution of the
simulation function. When "Write to Module (execution memory)" or "Write to Module (execution + flash
ROM)" is executed with the configuration tool or Operating condition settings batch-reset command' (Y3) is
turned on, Sampling data is not acquired (0) is stored in 'Sampling data acquired flag' (Un\G124). If sampling
data is acquired repeatedly, read the sampling data, and then issue a trigger start request.
■Trigger stop request
When Stop request (1) is set in 'Trigger stop request' (Un\G121) while Trigger ready (1) is stored in 'Trigger status monitor'
(Un\G123), a trigger stop request is issued.
After Trigger stop request is received, Trigger stop (0) is stored in 'Trigger status monitor' (Un\G123). The sampling data
generation stops in a module.
After the trigger stop, sampling data is not generated until a trigger start request is issued again even if the trigger condition is
satisfied.
• When simulation is executed with the configuration tool while the logic analyzer function is operating (while
Trigger ready (1) is stored in 'Trigger status monitor' (Un\G123)), the logic analyzer function stops
automatically. At a logic analyzer function stop, Trigger stop (0) is stored in 'Trigger status monitor'
(Un\G123). The logic analyzer function will not restart automatically after the simulation completion. To
restart the logic analyzer function, issue a trigger start request again.
• When "Write to Module (execution memory)" or "Write to Module (execution + flash ROM)" is executed with
the configuration tool while the logic analyzer function is operating (while Trigger ready (1) is stored in
'Trigger status monitor' (Un\G123)), the hardware logic control is suspended, and thus the logic analyzer
stops. When the auto trigger is enabled, the logic analyzer restarts after writing data into the module is
completed.
