Forwarding of Control Communication Frames
Function
Bandwidth Limit Function suppresses the Control
Communication Frame data volume to interexchange
among the WAN within the limit of the specified
bandwidth or less. Data overflow among the WAN
exceeding the contracted bandwidth is prevented.
When the Bandwidth Limit Function is activated, the
Preferential Forwarding of Control communication
Frames Function also becomes activated. In case
the transmission request to exceed the bandwidth
limit occurs, the control communication frame is
transmitted by giving the priorities based on the below
table. Even when the WAC Router abandons any data
exceeding the bandwidth limit by its Bandwidth Limit
Function; however, transmission of important control
communication frames can be protected.

Security function
In addition to the Vnet/IP’s security function, the WAC
Router has the function to destroy packets (such data
as unused protocols and unused port numbers) which
are not used in the WAC Router to reduce vulnerability.

Problems Cooling water pump equipment
Detecting the signs of cooling water pump failure
in various places in the plant
▲ Cooling water pumps are used in various
places in the plant.
Deterioration of the rotating equipment and
other components that make up the cooling
water pumps can lead to failure of the pumps.
Furthermore, if the cooling water pumps fail
and the cooling water temperature cannot be
maintained, the equipment that needs to be
cooled may also be damaged.
