Step 2:
Define the Device Type as Hybrid or Generic
To create a generic device from scratch, skip this section
and proceed to Step 3.
To create a new hybrid or generic device type based on a
TID, select a preconfigured device type and click Save
As to save a copy with a new name. The Save As dialog
is shown below:
Figure 45. Save As.... dialog box.
To create a hybrid device type, select YES from the
LINK EVENTS pulldown menu; selecting NO creates a
generic device type.
Saving As… creates a hybrid or generic device type with
the register map and all the display screens of the base
device, which may then be modified or deleted. Generic
devices created from scratch do not have any screens
configured initially; all their screens must be set up by
the user. See the section titled Notes on Hybrid/Generic
Devices later in this chapter for more technical details on
hybrid and generic device types.
Step 3:
Create the Device Type’s Register Map
Once a new device type has been created, its register
map must be defined. This enables the Monitor to
request the device’s data. Without knowing the device
type’s register map, the Monitor cannot know where to
retrieve data desired by the user.
From the Monitor Configuration Tool main menu, select
Modify an Existing Device Type and click OK. The
Modify Device Types dialog box appears (Figure 46).
Figure 46. Monitor Configuration Tool: Modify Device Types dialog.
The list box displays a list of all defined device types.
Generic device types and hybrid device types may
modified, deleted or saved as new device types.
Preconfigured devices (indicated by a YES in the Tightly
Integrated column next to the device type name) may not
be modified or deleted, but they may be Saved As… to
create a new hybrid or generic device type. Select the
new device type we defined earlier and click Modify to
display the Register Map dialog box (Figure 47).
(To delete a device type, select it and click DELETE.)
Figure 47. Monitor Configuration Tool: Register Map dialog.
The Register Map dialog box shown in Figure 47 allows
you to tell the Monitor where to find the data you’re
interested in, and what to call that piece of data – its
mnemonic. When you want to fetch the current reading
for phase A, it is far easier to remember (for example)
Amps_A than to remember R42000 or whatever the
register number may be.
Use the following commands to define the register map
for your new device type, then click OK to accept your
changes, or Cancel to exit the dialog without saving your
changes.
