“Terminal to Function” (TTF) programming principle
SPX ADVANCED APPLICATION MANUAL

2. “Terminal to Function” (TTF)
programming principle
In the conventional programming method, Function to
Terminal Programming Method (FTT), you have a fixed
input or output that you define a certain function for. The
applications mentioned above, however, use the Terminal
to Function Programming method (TTF) in which the
programming process is carried out the other way round:
Functions appear as parameters which the operator defines
a certain input/output for. See Warning on page 12.
2.1 Defining an input/output for a certain function
on keypad
Connecting a certain input or output with a certain function
(parameter) is done by giving the parameter an appropriate
value. The value is formed of the Board slot on the 9000x
control board (see 9000x User’s Manual, Chapter 6.2) and
the respective signal number, see below.

You want to connect the digital output function
Reference fault/warning (parameter 2.3.3.7) to
the digital output DO1 on the basic board OPTA1
(see 9000x User’s Manual, Chapter 6.2).
First find the parameter 2.3.3.7 on the keypad. Press the
Menu button right once to enter the edit mode. On the
value line, you will see the terminal type on the left (DigIN,
DigOUT, An.IN, An.OUT) and on the right, the present input/
output the function is connected to (B.3, A.2 etc.), or if not
connected, a value (0.#).
When the value is blinking, hold down the Browser button
up or down to find the desired board slot and signal
number. The program will scroll the board slots starting
from 0 and proceeding from A to E and the I/O selection
from 1 to 10.
Once you have set the desired value, press the Enter button once to confirm the change.
