Introduction
Function
The AK-PI 200 is an intermediary link allowing AKC and AKL type
controllers to be operated via a system manager, e.g. AK-SM 720.
The actual operation of the controllers is carried out with an AK-ST
500.
(AKC and AKL controllers use the DANBUSS data communication
system. The communication is controlled by a gateway, e.g. AKA
245.
In a solution with an AK-PI 200 and a system manager, the
gateway should not be used.)
Application
The AK-PI 200 is used on systems where the system unit is an
AK-SM 720 and where there are one or more controllers with
DANBUSS data communication.
The unit links the communication to DANBUSS so that the system
manager can present all the controllers on the system.
DANBUSS controllers 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 solution can be used on existing systems where the majority
are DANBUSS controllers and where it would be desirable to
change the system operation to a browser-based interface instead
of an AKM software interface.
Or it can be used on new systems where the majority might be
controllers with LON communication and other individual controls
can be AKC controllers.
Principle
The link between the system manager and the AK-PI 200 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.

Number of controllers
Up to 60 controllers can be connected to a single AK-PI 200. If
there are more than 60 controllers, two AK-PI 200 units should be
used.
Up to two AK-PI 200 units can be connected to a single system
manager, in other words up to 120 controllers on the DANBUSS
communication. If there are two AK-PI 200 units, the connection
to the system manager is led via a router or a switch.
Addresses
In principle there are three types of addresses:
IP addresses
Both the system manager and the AK-PI 200 must have an IP
address set.
The address can be either dynamic or static – the desired value is
selected with a setting. If static is chosen, an address must also be
set.
If the system can be accessed externally, the setting in the
system manager AK-SM 720 must always be set to static so that
the external connection always recognises the address and can
communicate with the unit.
(The IP address is set in a menu).
Network addresses
There must always be one and only one master system manager
on a network. This is defined with the address setting = 1. This
system manager controls the communication to all the other
controllers on the network. The PI unit is perceived as a controller
on the network and its address can be viewed in the IP list. (Up to
two PI units can be connected to the system manager, which is
master - i.e. has address =1)
(You set the network address on the front of the system units and
on the front of the PI units.)
Set the system manager to address 1.
If there are several system managers (slave network), set these to
addresses 2 to 10.
Each PI unit is set with a separate address. Select 12 or higher, e.g.
21.
Interconnection
When setting the system manager, a menu must also be set
in which the relevant AK-PI 200 chooses the network. The
system manager then knows the way to the different DANBUSS
controllers. The system manager must be version 1.20 or later.
Controller addresses
All controllers on the same network must have different addresses.
In other words, all controllers that are connected to a system
manager on either:
• the LON communication
• the MODBUS communication or
• the DANBUSS communication.
Start with the addresses on DANBUSS. They must be set with a DIP
switch and cannot be set to higher than 120.
The addresses on the LON and MOD buses can be set higher.
No more than 200 controllers can be connected to a system
manager.
DANBUSS communication: Address options 1 to 120
LON communication: Address options 1 to 999
MODBUS communication: Address options 1 to 247
Max. number of controllers: 200

Installation
Preparing controllers on DANBUSS
In an existing system
If it is an existing system in which the controllers have
previously been connected to a gateway, the pairing (network
number) with the gateway is registered so it can be set in AK-PI
200.
1. Register the network number for the later setting.
In a new system
1. Set the address of the controller
2. Switch it on if it is not already on
3. Set the desired language in the controller (connect the AKA
21 and set the language selection menu. Disconnect the
AKA 21 after entering settings).
Preparing TCP/IP connection
The AK-PI 200 must have a connection to the system manager –
both physically and with a software setting. This can take place in
one of the following ways:
1. Connection
a) Direct connection (only used if there is not an external
connection via a router).
The cable between the two units must be a crossed cable.
(A static IP address is always used here.)
b) Cables from the units are connected to a router or to a switch.
(A dynamic or static IP address is used here.)
2. Setting
a) Router
- Dynamic: There are no settings in the router
- Static: A static address range must be set in the router
b) AK-SM 720
- Select static if the connection between the system unit and
the AK-PI 200 is with a crossed cable or there is an external
connection to the system. Then set the IP address (an IP
address must be obtained from the local IT manager).
- Select dynamic if it is a closed system and the two units are
connected to a router or a switch.
c) In the AK-PI 200 the IP address is set either to static or to
dynamic.
- Select static if the connection between the system unit and
the AK-PI 200 is with a crossed cable. Then set the IP address
(an IP address must be obtained from the local IT manager).
- Select dynamic if it is a closed system and the two units are
connected to a router or a switch.
3. If a router or switch is connected, it must be turned on.

Preparing the system manager
1. Set its address on the front to 1 (there must always be a system
manager with address 1 on a network (1=master)). If there are
several networks and thus several system managers, they must
have addresses 2 to 10.
2. Connect the controllers to the two data communications, LON
and MODBUS. Switch on the controllers and set an address in
each controller. Addresses may not be duplicated – not even
with addresses on the DANBUSS network.
3. Apply power to the system manager
4. If a static IP address is used, this must be set
5. Enter the system manager's service PIN
Preparing the AK-PI 200
1. Set its address on the front (e.g. to 12)
2. Apply the power
3. If a static IP address is used, this must be set
4. Set network number for the DANBUSS group.
(In previously version (1.0x) of AK-PI 200 the number is not
visible but is fixed programmed to 1. If it is a updating of AK-PI
200 to version 1.1x it must be set to 1.)
5. (You can activate the“Service PIN” function at this point.
If you do, this means you do not have to start the scan function
in the next point.)
Perform the first scan
1. Start the scan function in the system manager – wait for the
results
(the controllers on the LON and MODBUS communication will
now be located and visible in the network overview).
2. Go to the next page of the network overview, which details the
IP registrations.
Check that the AK-PI unit is registered.
Interconnection
Define which AK-PI 200 unit the system manager should recognise
(several units can be registered but the system manager with
address 1 can only control two units.
1. There is a menu in the system manager in which settings must
be entered. Go to the Setup menu/Protocol interface (the
system manager must be version 1.20 or later).
2. Select the address of the AK-PI 200, which is to be connected to
the system unit.
Perform scan number 2 and locate the DANBUSS controllers
1. Perform a new scan of the system manager. Wait for the results.
(All controllers will now be located.)

• The installation of the data communication must be carried out
as specified in the guide to the RC8AC.
• The terminations must be in order.
• Language options in an AKC controller
When data is retrieved and sent to the AK-PI 200 and then on to
the system manager and operation software, it will appear in the
language selected in the controller.
If the wrong language is displayed, the AK-PI 200 must be
restored to factory settings and an associated file on the PC must
be deleted.
(C:Program files\ADAP-KOOL\Service tool\Data\Cashe\Code no).
The whole process must then be repeated, but this time with a
different language selected.
• Network addresses
Here is a small summary of the networks and addresses that can
occur:
11:001 is the master system manager
11:002 to 11:010 are slave networks controlled by 11:001
(the figure “11” keeps track of the networks and cannot be
changed).
11:012 to 11:999 are addresses for units on the network. The
units can be AK-PI 200 units or wireless units, or they can be
controllers in which the data communication takes place via
TCP/IP.
1: xxx will be controllers that are registered under the master
system manager.
2: xxx will be controllers that are registered under slave network
number 2.
