Setting the monitoring condition
• Set a condition to generate a hold trigger in 'CH1 Level trigger condition setting' (Un\G540).
• Set a value where a hold trigger is generated to 'CH1 Trigger setting value' (Un\G542).
The following figure shows the relation between setting items to be configured for the initial setting of a level
trigger.
For example if trying to generate a hold trigger when a value in 'CH1 Digital output value' (Un\G400) is greater
than 1000, set as follows.
• 'CH1 Level trigger condition setting' (Un\G540): Rise (1)
• 'CH1 Trigger data' (Un\G541): 400
• 'CH1 Trigger setting value' (Un\G542): 1000
Setting value Description
1: Level trigger (Condition:
Rise)
(a) A hold trigger is generated when the relation between the values changes
from "Stored value of a buffer memory area to be monitored ≤ Trigger setting
value" to "Stored value of a buffer memory area to be monitored > Trigger
setting value".
(b) A hold trigger is generated when the relation between the values changes
from "Stored value of a buffer memory area to be monitored ≥ Trigger setting
value" to "Stored value of a buffer memory area to be monitored < Trigger
setting value".
A hold trigger is generated under the
condition (a).
2: Level trigger (Condition:
Fall)
A hold trigger is generated under the
condition (b).
3: Level trigger (Condition:
Rise and fall)
A hold trigger is generated under the
condition (a) or (b).
