Buffer memory name
CH Alert set value 1
CH Alert set value 1 (If using FX3 allocation mode)
■Alert mode
Set the alert mode of Alert 1 in the following buffer memory area. The alert mode of Alert 1 corresponds to 'CH1 Alert set
value 1' (Un\G434).
• 'CH1 Alert 1 mode setting' (Un\G533)
■Setting range
The write set value units and settings range depend on the alert mode that has been set.
