DaqView User’s Guide 888194 The Setpoints Window 11-7

Setpoint Status Register

A setpoint status register can be used to check the current state of the 16 possible setpoints. In the register,

Set

poi

0 is the least significant bit and Setpoint 15 is the most significant bit.

Each setpoint is assigned a value of 0 or 1. “0” indicates that the setpoint criteria is not met, i.e., the

ition is false. “1” indicates that the criteria has been met, i.e., the condition is true.

In the following example, the criteria for set

poi

s 0, 1, and 4 is satisfied (True); but the criteria

for the other 13 setpoints has not been met.

Setpoint # 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0

True ( 1 )

False ( 0 )

0 0 0 0 0 0 0 0 0 0 0 1 0 0 1 1

<<< Most Significant Bit Least Significant Bit >>>

From the above table we have 10011 binary, or 19 decima

l, derived as follows:

Setpoint 0, having a True state, shows “1;” giving us decimal “1.”

Setpoint 1, having a True state, shows “1;” giving us decimal “2.”

Setpoint 4, having a True state, shows “1;” giving us decimal “16.”

1 2 ... 62 63 64 65 66 67 68 69 70 71 72 ... 85 86
