Front-Panel Interface (Only on Models With LCD)
Rotating Default Display
In the preceding example, only two display points (DP1 and DP2) and their
corresponding display point labels are set. If additional display points and
corresponding display point labels are set, the additional enabled display point
labels join the rotation (display time = SCROLD) on the front-panel display.
The SCROLD setting is made with the SET G command and reviewed with
the SHO G command.
Display point label settings are set with the SET T command or viewed with
the SHO T command via the serial port [see Section 9: Setting the Relay and
SHO Command (Show/View Settings) on page 10.25].
For more detailed information on the logic behind the rotating default display,
see Rotating Default Display (Only on Models With LCD) on page 7.34.
Scroll Lock Control of
Front-Panel LCD
The rotating default display can be locked on a single screen. (See Rotating
Default Display (Only on Models With LCD)). Access the scroll lock control
with the {OTHER} pushbutton.
