Proportional Integral Derivative Instruction 9-13
Setpoint Out Of Range (SP)
This bit is set (1) when the setpoint:
• exceeds the maximum scaled value, or
• is less than the minimum scaled value.
PV Out Of Range (PV)
The process variable out of range bit is set (1) when the unscaled process
variable (PV):
• exceeds 16,383, or
• is less than zero.
PID Done (DN)
The PID done bit is set (1) for one scan when the PID algorithm is computed.
It resets automatically.
