Large Character Screens
Large character screens are also used for displaying numeric register
values. They display up to four registers on one screen. The large
character format is well suited for viewing from a distance. Data in large
character screens are updated once per second, regardless of the update
rate of the register on the connected device.
To set up a large character screen:
1. Enter the parameter handle of the first register you want to display on
the screen, then press ENTER. If you want to keep the register that is
currently in use, press the button labeled KEEP PREVIOUS.
2. Repeat step 1 for the remaining 3 registers that you want to display. If at
any point you want to return to the main menu, press the ESC button.
You do not have to specify a handle for every register if you do not want
to use all 4 lines. Pressing ENTER will skip a line; in the display screen,
that line will be left blank.
Bar Graph Screens
The MGT offers two different kinds of bar graph screens to display numeric
registers on the connected device (a 4-channel and a 6-channel display).
These displays offer a graphical representation of fluctuations in the register
values and they are suitable for viewing from a distance. For both the 4-
and 6-channel displays, you can define a minimum and a maximum
boundary of the bar graph and hence control the scale of the graph. If you
have linked any of the registers you are displaying to a Minimum or
Maximum module, you can also display the minimum and maximum values
attained by the register.
4-Channel Bar Graph
The 4-channel bar graph displays four numeric register values in bar graph
form. If you are displaying high-accuracy registers, the graph is updated
every second. If you are displaying high-speed registers without minimum
and maximum values indicated, the graph is updated every 100 msec (with
the minimum and maximum values displayed, the update rate is 1 second).
The register label is
displayed (or the
register name if no
label has been setup).
The value in the
register is
displayed and
updated once per
second.
