c. Update period and Max Update Period
Set to
Update Period and Max Update Period.
When the period that is earlier than the operation
period of each process value was set, it is set
automatically to become bigger than an operation
period of the device.
For
Update Period, set the value that is smaller
than
Max Update Period.

Continuous
Burst Message is transmitted
continuously.
Window
In “Window” mode, the Trigger Value
must be a positive number and is the
symmetric window around the last
communicated value.
Rising
In “Rising” mode, the Burst Message
must be published when the source
value exceeds the threshold
established by the trigger value.
Falling
In “Falling” mode, the Burst Message
must be published when the source
value fall below the threshold
established by the trigger value.
On-change
In “On-change” mode, the Burst
Message must be published when the
source value on change established
by the trigger value.
