AK-PI
100
Introduction
Function
The AK-PI 100 is an intermediary link allowing Woodley type units
to be operated by an AK-SC 255 system controller.
This way of operating the Woodley units replaces the previous
Woodley S5 operating interface.
Application
The AK-PI 100 is used on systems with an AK-SC 255 system con-
troller, but which still contain older Woodley type units.
These types can be:
• Woodley MDM units
• Woodley 4 way TPI cards
• Older units connected to the WTP bus (WTP = Woodley Third
Party)
Measurements and status readings from the individual Woodley
units are uploaded to the AK-PI 100 and on to the AK-SC 255,
where the data is presented in the same way as other ADAP-
KOOL(r) units.
Principle
The AK-SC 255 and the AK-PI 100 are linked by Ethernet.
For a straightforward connection, the two units can be linked by a
switch.
In this case, the IP addresses are set to static addresses. You can
choose any addresses,
but only
if nothing else is connected.
(It is easiest to use a router and dynamic address allocation. In this
case, the router allocates one address to the AK-SC 255 and an-
other to the PI unit. You can only use this solution if the system is
self-contained with no contact to an external operating interface.)
In larger systems or if IP communication takes place from the sys-
tem, the connection must be based on a router or a switch.
If a router is used, the IP address of the AK-PI 100 may be dynamic,
but the address of the AK-SC 255 must be static.
If a switch is used, both must be static.
You will need to request static addresses from the IT department
yourself, and then configure the addresses in both units. You
should always use this solution if the system is accessed by an
external service company, for example for log extraction, alarm
handling or servicing.
