6. STARTUP
6.1 Switch-on
When the controller is switched on it runs a test on the secondary display,
lighting up the segments one by one.
6.2 Private and shared terminals
All pCO5+ controllers can be connected to each other and to other
CAREL devices in a pCO local area network (pLAN) without requiring
optional devices, allowing the communication of data and information
from one location (node) to another. The terminals can show the
variables (temperature, humidity, pressure, I/O, alarms) from just one
controller at a time. The terminal does not need to be connected to the
controller during normal operation, but can be used just for the initial
programming of the main parameters. If one or more terminals are
disconnected or malfunctioning, the application program continues to
work correctly on each controller. Generally, the application program can
monitor the status of the network and intervene as necessary to ensure
the continuity of control functions. The fi gure below shows a possible
pLAN network connection diagram.

Fig. 6.a
All the terminals and controllers in the network must communicate at the
same speed. The speed is adjusted automatically.
A maximum of 32 units can be connected, including:
•
pCO controllers, which run the control program;
•
external modules, which provide extended functionality (such as the
EVD Evolution driver);
•
terminals.
Every device belonging to a pLAN network is identifi ed by an address,
i.e. a number from 1 to 32. The number 32 can be assigned only to a
terminal. Programs for diff erent applications (e.g. chillers, air-conditioners,
compressor racks, etc.) cannot be automatically integrated into a local
network – they must be confi gured according to the system’s architecture
using the CAREL development tool.
Each controller connected to the network can simultaneously manage
up to 3 terminals in the pLAN network. The values are displayed on the
terminals at the same time and not independently, as if the keypads and
the displays were connected in parallel. Because of that, the controller
cannot drive diff erent kinds of terminals at the same time.
Each terminal associated with a certain controller is defi ned as:
- private (“Pr”) if it displays only the output of that controller;
- shared (“Sh”) if either automatically or from the keypad it can be switched
between various controllers.
Each pCO constantly updates the displays on the private terminals, while
the shared terminals (if present) are updated only by the pCO that is
controlling the terminal at that time.
The fi gure below illustrates the logic of the relations.

In this example the shared terminal is associated with 4 pCO controllers,
but at this instant only controller 1 can display data and receive commands
from the keypad. Switching between controllers occurs in sequence (1-
>2->3->4->1...) by pressing a button defi ned by the application program;
however it can also be done automatically when requested by the
program. For example, a pCO may request control of the shared terminal
to display alarms or, vice-versa, relinquish control to the next pCO after a
set time (cyclical rotation).
Data on the number and type of terminals is determined during initial
network confi guration and saved in the permanent memory of each pCO
controller. Details of the confi guration procedure are described below.
See the “Installation” chapter for information on the cables to use for the
electrical connections.
6.3 Setting the controller’s address
The controller’s pLAN address is factory-set as 1.
There are two ways to set a controller’s address:
1.
using the A button (see fi gure below) located on the left of the
7-segment display. It can be accessed using the tip of a screwdriver
(ø<3 mm);
2.
using a terminal connected to the pLAN network.
1. Displaying the pLAN address
Procedure:
•
briefl y press the A button (no more than 5 s) to display the controller’s
current pLAN address. Five seconds after releasing the button the
display is cleared.
