A.3
System confi gurations with more than
one pLAN board
If the system confi guration involves the connection of more than one
board in a pLAN, the addresses must be set correct before select a
solution of confi guration.
For the addresses to be assigned to the pRack pR300 boards see Appendix
A.1.
pRack pR300 can use two user terminals (as well as a built-in terminal)
with addresses 31 and 32. The default user terminal address is 32, so only
if a second terminal is required must the address of this be set to 31,
as described below. The address of the terminal is also required when
having to set the address of the pRack pR300 boards, when multiple
boards are connected to the pLAN.
After having correctly connected and confi gured the pLAN network
of pRack pR300 boards, the system can be confi gured as described in
paragraph 4.1.
A.3.1 Setting the address of the terminal
The pRack pR300 user terminal is supplied with the default address 32,
allowing the terminal to be used without requiring any additional operations;
nonetheless, in order to use an additional terminal or confi gure the pLAN
address of the boards, it needs to be changed according to the following
procedure:
1.
power the terminal via the special telephone connector;
2.
press the 3 buttons, , and together for at least 5 seconds;
the terminal will display a screen similar to the one below, with the
cursor fl ashing in the top left corner:
Display address
setting.........:32
I/O Board address:01
3.
press once: the cursor will move to the “Display address setting”
fi eld;
4. select the desired value using and , and confi rm by pressing
again; if the value selected is diff erent from the value saved, the
following screen will be displayed and the new value will be saved to
the display’s permanent memory.
Display address
changed
Note : if the address fi eld is set to 0, the “I/O Board address” fi eld is no
longer displayed, as it has no meaning..
Important
•
if the settings are not made correctly, the text and the images on the
display will be displayed incorrectly and out of order.
•
if during this operation the terminal detects inactivity of the pRack
board whose output is being displayed, the display is cleared and a
message similar to the one below is shown.
