AK-PI
300
Introduction
Function
The AK-PI 300 is an intermediary link allowing Daikin type
controllers to be operated via a System Manager, e.g. AK-SM 720
or similar.
The actual operation of the controllers is carried out with an AK-ST
500.
Daikin units include data communication, where communication
is controlled by a Daikin Comm. box or a Daikin RTD-network.
The three units: “Outdoor unit”, “Booster unit” and “Indoor unit”
can be connected to the Comm. box and “Indoor unit” to RTD-
network.
Application
The AK-PI 300 is used on systems where the system unit is an
AK-SM 720 and where there is/are one or more Daikin type units.
AK-PI 300 links communication to Daikin so that the system
manager can present all the controllers on the system.
Daikin units are presented on an equal footing together with
LON RS 485 controllers and MODBUS controllers.
All controllers can be viewed and operated from the system
manager’s network overview.
The network list on the right shows two RTD-networks, and an
outdoor unit. The outdoor unit is connected via a Comm. box.
Principle
The link between the system manager and the AK-PI 300 is via a
TCP/IP.
In this very simple connection the two units can be connected to
each other via a crossed cable.
This is where the IP addresses are set to static addresses.
On larger systems or where there is also outgoing IP
communication from the system, the connection must be made
via a router.
Here the IP addresses can be dynamic, but if there is
communication to the system from outside, they must be static.
If you are not sure whether you should select static or dynamic, abide
by the following recommendation:
Dynamic is the easiest. Here the router itself allocates an address
for the system manager and another for the PI unit. But you
should only select this solution if the system is closed without a
connection for an external operation interface.
With static you must obtain a couple of addresses yourself at the
local IT department and you must also set the addresses yourself
in the two units. This solution must always be used when the
system is operated by an external service company, e.g. for log
collection, alarm management or service.
