field later, you can use the Unassign button to clear the
field, then Assign a different register to be displayed.)
NOTE: The two sorts of fields are mutually exclusive.
You cannot assign a register to a label field, nor can you
enter a label into a data field. If you attempt any other
action than what is allowed for a particular field, the
program will display a warning box telling you what sort
of field it is and what needs to be placed in the field.
Inserting Screens
To add additional screens, press the INSERT BEFORE
or INSERT AFTER button. (Conversely, the current
screen may be deleted by pressing the DELETE
SCREEN button.) A new screen will be created and
placed before or after the current screen in the list of
screens. The order of the screens set up here determines
the order in which they will be displayed on the Monitor.
Pressing the Insert Before or Insert After button displays
the Insert Screen dialog.
Figure 51. Insert Screen dialog.
Select the format of the screen you wish to insert by
pressing the Format #1, Format #2, or Format #3
buttons, then press OK. A new screen is created with the
selected format, and you are returned to the Customize
Display dialog with the new screen displayed for you to
fill in with labels and associated registers.
Reset to Defaults
The Reset to Defaults button is available if the hybrid or
generic device being customized is based on a tightly
integrated device. Pressing the Reset to Defaults button
restores the register map and displays to the original
settings present when the TID device type was copied.
Notes on Hybrid/Generic Device Types
This section will provide some additional background
information on the operation of the Modbus Monitor
with regard to device types.
Special Handling Registers
The tightly integrated device types support special
handling registers which are not available to generic
devices. These special handling registers give the
Modbus Monitor additional information about the
register. In particular, they allow the Modbus Monitor to
associate a string with a register’s value or allow the
displayed value of one register to be modified by the
value of another register.
For example, many devices have a register that indicates
the Last Trip Cause, where a register value of 10
indicates a Long Time Trip and the value of 11 indicates
a Short Time Trip. The Modbus Monitor could easily
display the actual register value, but this is not very
descriptive to the user. By defining the register as a
special handling register, the Modbus Monitor can
display “Long Time Trip” or “Short Time Trip” as
appropriate. The special handling registers are only
available for set of registers defined by the default types,
and cannot be modified by the user.
Hybrid Device Types
Hybrid devices are redefinitions of the tightly integrated
device types specified by GE. When you Save As… to
create a copy of a tightly integrated device type, you’re
creating a copy of a TID which you may then modify.
(Tightly integrated device types may not be modified.)
The hybrid device types retain all the special handling
registers and event logging features of the tightly
integrated device upon which it was based. This is the
function of the Link Events selection in the Save As…
dialog box. Selecting YES in Link Events creates a
hybrid device with all the special handling registers and
event logging features of the base device; selecting NO
in Link Events creates a generic device type, which do
not support special handling registers or events handling.
When adding additional registers to the hybrid device,
there is no guarantee of support for the data format and
no way to define the register as a special handling
