Link to Alarm
The PV display color changes by linking to the alarm 1 or alarm 2.
The following is an example of operation linking to alarm 1.
Set the alarm-1 type to “PV high limit alarm” and alarm-1 setpoint to “80°C.”
When the active color PV display switch is set to”2,” PV display color changes from white
to red if PV exceeds the alarm-1 setpoint.
The red-to-white switching action can be set.

ChangebyDeviation
The PV display color changes by deviation (PV – SP).
Set the PV color change high limit to “10°C” and the PV color change low limit to “5°C”
as deviation band for the current target setpoint “50°C.” PV display color changes from
white to red if PV is out of the deviation.
The red-to-white switching action can be set. There is no hysteresis.
