Setpoint Configuration for Output Control 6-11
The Setpoint Status Register
Regardless of which software application you are using with a DaqBoard/3000 Series device, a setpoint
status register can be used to check the current state of the 16 possible setpoints. In the register, Setpoint 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 condition is false. 1 indicates that the criteria
has been met, i.e., the condition is true.

From the above table we have 10011 binary, or 19 decimal, 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.”
