When the time at no communication data exceeds the setting time of F17.04, it will be considered as
communication time out.
• When F17.04 = 0, it will not detect communication time out.

F17.06 defines the action selection at commmunication time out.
F17.07 defines the action selection at communication fault.
In the communication command setting mode, F17.08 will define the action selection when
communication peripheral device fault is alarmed.
