Chapter 4
Operation
Introduction
During normal operation, the Monitor collects data from
devices on the Modbus segments. The data may be
viewed locally on the display.
When not in immediate use, a screen saver is activated to
prevent screen burn-in. The Monitor automatically
activates its built-in screen saver after 10 minutes
without user interaction. Pressing any key returns the
display to normal operation.
Keypad/Menu Navigation
The Modbus Monitor’s functions are menu-driven,
accessed using the up arrow and down arrow keys to
highlight desired selections, then the SELECT key to
accept your choices. Should you inadvertently enter a
wrong screen, pressing the BACK key will return you to
the previous screen. Pressing the HELP button displays
context-sensitive help regarding the current screen.
The Monitor keypad has 10 keys, located on its front
panel directly below the screen. At the bottom of the
screen is a key bar, displaying a command above each
key that has a function at the current time.
At any given time, various options are listed on the
display, one of which will be highlighted by a ‘selection
bar’. Pressing the up-arrow or down-arrow key on the
keypad scrolls the selection bar up or down the list of
items. Pressing the SELECT selects the currently
highlighted menu item.

Figure 36. Monitor Main menu (details).
The indicator bar at the top of the screen contains several
fields. An indicator at the top left corner will display
“HOST” if the Monitor is acting as master to the
Modbus segments. To the right of the Host indicator is
the EVENT indicator. If this is present, it indicates that
there are new events to view. Lastly, in the upper right
corner of the display, the date and time are shown.
Beneath the indicator bar is the main body of the screen,
usually presenting a menu, a screen of device data, or a
list of events.
Under the main body of the screen is another horizontal
bar of data - the status bar. The status bar contains
system messages such as STATUS: OK if all is well, or
error messages if problems have occurred. While
viewing device data, this area contains device
information such as device name, device type, location,
Modbus segment and network address.
Beneath the status bar, the key bar display shows which
keys are currently available and active; i.e., which keys
have an effect for the current display.
The first option on the main menu, View: Monitor
Configured Devices, is the focus of this chapter. Option
2, Setup, has been covered in Chapter 3, and Option 3,
Diagnostics, is the subject of Chapter 5.
