Emerson Rosemount OCX8800A - Proportional;Integral;Derivative (PID) Function Block

Potential cause
Scaling parameters are set incorrectly.
Recommended action
Set XD_SCALE.EU0 and EU100 to match that of the transducer block channel
value.
Cannot set HI_LIMIT, HI_HI_LIMIT, LO_LIMIT, or LO_LO
LIMIT values
Potential cause
Limit values are outside the OUT_SCALE.EU0 and OUT_SCALE.EU100 values.
Recommended action
Change OUT_SCALE or set values within range.
8.9 Proportional/integral/derivative (PID)
function block
The PID function block combines all of the necessary logic to perform
proportional/integral/derivative (PID) control. The block supports mode control,
