INPUT

Summary:

int	input(n);
int	n;	Input number

Description:

The input function will return the present value of an input specified by n1. When n1 is a number from 1 to 16, the return value is from the corresponding input. For n1 equals 17 to 20, the return values are the following:

17The built in temperature sensor in degrees F.

18The built in temperature sensor in degrees C.

19Battery backup level in volts DC.

20AC power, 1 = on, 0 = off.

Return value:

The input function returns the present value of an input specified by n1. This will be the appropriate look up table value if the input is analog. If the input is a dry contact, an open condition will return a 1, and a closed condition will return a zero.

Example:

This program will generate an alarm condition if input 12 is greater than 100. It will also generate alarm condition 13 if AC power fails. Please note that for input 13 to alarm as power failure, the ITYPE must be set to USER DEFINED (see ITYPE section), and the low alarm limit set to 90.

main()

{

if (input(12) > 100)

{

alarm(12);

}

set_input(13,(input(20)*110));

}
