a) Burst Command
Select the transmission data at Burst Command
parameter.
Burst Command Command parameter
Cmd1: PV Variable assigned to PV
Cmd2: % range/current % range/current (Output in %
and Loop current)
Cmd3: Dyn vars/current Process vars/current
(Loop current, PV, SV, TV,
QV)
Cmd9: Device vars
w/Status
Process vars/% range/current
Mapping by user
Cmd48: Read
Additional Device
Status
Self diagnosis information
b) Burst Variable Code
This parameter need to be set when Burst
Command is Cmd9:Device vars w/Status (up to
eight items).

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.

Display Item Contents
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.
