STARTUP
6.1 Switching
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 terminal
All c.pCO controllers can be connected to each other in a local area
network (pLAN, see Figure 6.a) in order to share one or more terminals.
Shared 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 continuity of the control functions. The figure
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 adapted automatically.
A maximum of 32 units can be connected, including:
•
c.pCO controllers, which run the control program;
•
terminals.
Every device belonging to a pLAN network is identified by a unique
address, i.e. a number from 1 to 32. The number 32 can be assigned only to
a terminal. Programs for different applications (e.g. chillers, air-conditioners,
compressor racks, etc.) cannot be automatically integrated into a local
network – they must be configured according to the system 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 manage different kinds of terminals at the same time.
Each terminal associated with a certain controller is defined 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 c.pCO constantly updates the displays on the private terminals, while
the shared terminals (if present) are updated only by the c.pCO that is
controlling the terminal at that time.
The figure below illustrates the logic of the relationships:

In this example, the shared terminal is associated with 4 controllers, but
at this instant only controller 1 can display data and receive commands
from the keypad. Switching between controllers occurs:
1.
using a command in the system menu;
2.
in sequence (1->2->3->4->1...) by pressing a button defined by the
application program; however it can also be done automatically
when requested by the program. For example, a c.pCO may request
control of the shared terminal to display alarms or, vice-versa,
relinquish control to the next c.pCO after a set time (cyclical rotation).
Data on the number and type of terminals is determined during initial
network configuration and saved in the permanent memory of each
c.pCO controller. Details of the configuration procedure are described
below. See the “Installation” chapter for information on the cables to use
for the electrical connections.
6.3 Setting the controller pLAN address
The controller pLAN address is factory-set as 1.
There are two ways to set a controller address:
1.
using button A (see the figure below) located next to the 7-segment
display. This can be accessed using the tip of a screwdriver (ø<3 mm);
2.
from the system menu (see Chapter 7).
