5.6 Communication via P1 - only CU230P-2 HVAC, CU230P-2 BT
P1 is an asynchronous master-slave communication between what is known as a Field
Cabinet (master) and the FLN devices (slaves). FLN stands for "Floor level network".
The master individually addresses the various slaves. A slave responds only if the master
addresses it. Communication between the slaves is not possible.
A Field Cabinet can have several FLN ports. You can connect up to 32 FLN devices to each
FLN port (slaves).
Settings in the controller
In the Field Cabinet, for each slave you must install what is known as a "Logical controller
(LCTR) point". In addition, in the Field Cabinet you must define the "Point numbers" for
communication.
An overview of the "Point Numbers" is provided on the following pages.
Overview
Procedure
Proceed as follows to set communication via P1:
1. Select the default setting 114.
– With STARTER: under Control Unit/Configuration "Default settings of the
– with BOP-2 for the basic commissioning under Step "MAc PAr P15":
– using the expert list or parameter number:
2. Set the inverter address.
3. Make additional changes based on the parameters listed in the following sections.
4. If you are working with STARTER, backup the settings with
This means that you have made the settings for communication via P1.
