CV Lower Limit Alarm (LL)
The control variable lower limit alarm bit is set (1) when the calculated CV
output is less than the lower CV limit.
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
• exceeds 16,383, or
• is less than zero.
Done (DN)
The PID done bit is set (1) for one scan when the PID algorithm is
computed. It resets (0) whenever the instruction is scanned and the PID
algorithm was not computed (applies to timed mode only).
