(8) Condition for inspection
Designate the news conditions to monitor the devices of the PLC CPU.
The following table lists the comparison conditions for the designated device.
Condition of comparison
News condition
Rise
When switching from off to on is detected.
Bit device
Drop
When switching from on to off is detected.
No condition setting
For each monitoring.
Device value = monitoring value
When the monitoring device value and the value set by the user are the
same.
Device value
≠
monitoring value
When the monitoring device value and the value set by the user are
different.
Device value < monitoring value (unsigned)
When the monitoring device value is equal to or less than the value set by
the user.
Device value < monitoring value (unsigned) When the monitoring device value is less than the value set by the user
Device value > monitoring value (unsigned)
When the monitoring device value is equal to or greater than the value set
by the user.
Device value > monitoring value (unsigned) When the monitoring device value is greater than the value set by the user.
Device value < monitoring value (signed)
When the monitoring device value is equal to or less than the value set by
the user.
Device value < monitoring value (signed)
When the monitoring device value is less than the value set by the user.
Device value > monitoring value (signed)
When the monitoring device value is equal to or greater than the value set
by the user.
Word device
Device value > monitoring value (signed)
When the monitoring device value is greater than the value set by the user.
(9) Monitoring value
Designate the comparison value of the condition of comparison given in (8)
above.
(10) Notification data storage device (News data storage device)
The condition device that stores the news data is set when the news condition is
satisfied.
When the CPU monitoring condition shown in (1) is "No setting", GX Developer
automatically sets the condition device, so the user does not need to set it.
(11) Notif. data points (News points)
Designate how many devices should be read (number of points read) from the
devices designated in (10) above.
(a) The number of device points that can be sent at a time is calculated as
follows.
Word device points 2 + bit device points
÷
8 (round up)
≤
1920
1) Designate the settings so that the total number of points satisfies the
equation above when multiple news conditions are satisfied when
monitoring multiple condition devices.
2) When multiple bit devices are to be designated, be aware of following:
• One device occupies 16 device points.
