State Of The Plan - CIAT AirControl CTA Manuel De Régulation

If the nn field is set to '0', the terminal will use the Point-to-Point Protocol (not the pLAN) to communicate with the controller and
the "I/O Board address: xx" field will disappear as it will not be necessary.
3.3.2 Assigning private and shared HMI terminals
EN
Follow the procedure below if, at this point, it is necessary to change the list of terminals associated with each controller:
• enter configuration mode by pressing the   and  buttons as described in the previous section;
• press  until the cursor moves to the "I/O board address" field;
• using the   buttons, select the desired address for the controller. The only values selectable will be those of the controllers
that are on the network. If the pLAN network is not working correctly or if no controllers are present, the field cannot be changed
and will display a "—";
• press the button once more. the following mask sequences will be displayed:
• the button also moves the cursor between fields and the   buttons change the value in the active field. The P:xx field shows
the address of the selected controller. In the example above, controller No. 01 is selected;
• to exit the configuration procedure and store the data, select "YES" in response to "OK?" and confirm with the button.
In the case of a shared display for a set of units (maximum 31), the terminal must be configured on each unit in "Sh" mode.
The fields in the "Adr" column contain the addresses of the terminals associated with the controller whose address is 01; the "Priv/
Shared" column shows the terminal type.
Warning: HMI terminals do not have a printer output and therefore cannot be configured as "Sp" (shared printer).
If the terminal remains inactive (no buttons pressed) for more than 30 seconds, it will automatically exit configuration mode
without saving any changes made.
3.3.3 Checking the pLAN address
The pLAN address is displayed in the top left of the main screen, the pLAN NETWORK pL1 screen and the pr1 screen of the
"Prog" menu.

3.4 State of the pLAN

When the system starts up, the pLAN network may encounter a number of problems (card fault and terminal start-up) caused by
incorrect connections or a wrong address. The state of the pLAN network can be displayed in real time on a special mask in order
to identify which devices (controller or terminal) are correctly connected and addressed.
To display this special page, simultaneously press   and  on any terminal on the network for at least 10 seconds. After the
first 5 seconds, a page is displayed; after 5 more seconds, the next page appears:
Once on the screen, network addresses 1 to 32 are displayed. The small rectangles represent the terminals and the large
rectangles , the controllers. If symbols appear then disappear, the pLAN may be unstable or, more likely, two components share
the same address. The number after Term indicates the address of the terminal used. The example shows that the network is
made up of 3 controllers with the addresses 1, 2, 25 and 4 terminals with the addresses 3, 4, 15 and 26. Once the page has been
verified, turn off the power, check the connections and addresses, then turn the power back on.
