Special Input Functions; Interrupt; Counter; Fig. 8-3: Protection Circuitry For The Inputs - Addi-Data ADDINUM CPCI-1500 Technical Description

Technical description
WARNING!
Do you operate all inputs with the same voltage supply? The voltage
supply must deliver at least 16 x 6 = 96 mA.
The maximum input voltage is 30 V.
Transil diodes, Z diodes, C filters and optical couplers protect the system bus
from noise emitted by the peripheral. The effects of inductive and capacitive
noise are thus reduced.
The board requires no initialisation to read the 24 V digital information. After
successful power ON reset, data is immediately available on the board.

Special input functions

1) Interrupt:

The inputs 1 to 14 can generate an interrupt.
Inputs 1 to 8: It is possible to declare an OR or AND event to generate an interrupt.
Inputs 9 to 14: It is possible to declare an OR event to generate an interrupt.
Inputs 15 & 16: are not interruptible and are not used in events.

2) Counter

Counter 1:
Counter 2:
Counter 3
Chapter 8
Input 14 signal input
Input 10 signal input
Input 11 can be used for a "trigger" function
Input 12 can be used for a "gate" function.
Input 15 signal input
Input 16 can be used as a "gate" function.
