Configuring the Island Bus
How to Install the STB XMP 4440 Optional Removable Memory Card
Introduction
The STB XMP 4440 removable memory card is a 32-kbyte subscriber identification
module (SIM) that lets you store (see p. 174), distribute, and reuse custom island
bus configurations. If the island is in unprotected (edit) mode (see p. 175) and a
removable memory card containing a valid island bus configuration is inserted in the
NIM, the configuration data on the card overwrites the configuration data in Flash
memory, and is adopted when the island starts up. If the island is in protected mode,
the island ignores the presence of a removable memory card.
The removable memory card is an optional Advantys STB feature.
Note: Network configuration data, such as the fieldbus baud setting cannot be
saved to the card.
Physical
Description
CAUTION
LOSS OF CONFIGURATION—MEMORY CARD DAMAGE OR
CONTAMINATION
The card’s performance can be degraded by dirt or grease on its circuitry.
Contamination or damage may create an invalid configuration.
Use care when handling the card.
Inspect for contamination, physical damage, and scratches before installing the
card in the NIM drawer.
If the card does get dirty, clean it with a soft dry cloth.
Failure to follow these instructions can result in injury or equipment damage.
The card measures 25.1 mm (0.99 in) wide x 15 mm (0.59 in) high x 0.76 mm
(0.30 in) thick. It is shipped as a punch-out on a credit-card-sized plastic card, which
measures 85.6 mm (3.37 in) wide x 53.98 mm (2.13 in) high.
Note: Keep the card free of contaminants and dirt.

Installing
the Card
Use the following procedure to install the card:
Step
1
Action
Punch out the removable memory card from the plastic card on which it is
shipped.

Make sure that the edges of the card are smooth after you punch it out.

2
Open the card drawer on the front of the NIM. If it makes it easier for you to work,
you may pull the drawer completely out from the NIM housing.
3
Align the chamfered edge (the 45° corner) of the removable memory card with
the one in the mounting slot in the card drawer. Hold the card so that the chamfer
is in the upper left corner.
4
Seat the card in the mounting slot, applying slight pressure to the card until it
snaps into place. The back edge of the card must be flush with the back of the
drawer.
5
Close the drawer.

Removing
the Card
Use the following procedure to remove the card from the card drawer. As a handling
precaution, avoid touching the circuitry on the removable memory card during its
removal.

Action
1
Open the card drawer.
2
Push the removable memory card out of the drawer through the round opening
at the back. Use a soft but firm object like a pencil eraser.

How to Configure the Island Bus with the STB XMP 4440 Optional Removable
Memory Card
Introduction
A removable memory card is read when an island is powered on. If the configuration
data on the card is valid, the current configuration data in Flash memory is
overwritten.
A removable memory card can be active only if an island is in edit mode. If an island
is in protected mode (see p. 175), the card and its data are ignored.
Configuration
Scenarios
The following discussion describes several island configuration scenarios that use
the removable memory card. The scenarios assume that a removable memory card
is already installed in the NIM:
initial island bus configuration
replace the current configuration data in Flash memory in order to:
apply custom configuration data to your island
temporarily implement an alternative configuration; for example, to replace an
island configuration used daily with one used to fulfill a special order
copying configuration data from one NIM to another, including from a failed NIM
to its replacement; the NIMs must run the same fieldbus protocol
configuring multiple islands with the same configuration data
Note: Whereas writing configuration data from the removable memory card to the
NIM does not require use of the optional Advantys configuration software, you must
use this software to save (write) configuration data to the removable memory card
in the first place.
Edit Mode
Your island bus must be in edit mode to be configured. In edit mode, the island bus
can be written to as well as monitored.
Edit mode is the default operational mode for the Advantys STB island:
A new island is in edit mode.
Edit mode is the default mode for a configuration downloaded from the Advantys
configuration software to the configuration memory area in the NIM.

Configuring
Multiple Island
Buses with
the Same Data
Use the following procedure to set up an island bus with configuration data that was
previously saved (see p. 174) to a removable memory card. You can use this
procedure to configure a new island or to overwrite an existing configuration. Note:
The execution of this procedure destroys your existing configuration data.
Step
Action
1
Install (see p. 49) the
removable memory card
in its drawer in the NIM.
2
Power on the new island
bus.
Result
The configuration data on the card is checked. If the data
is valid, it is written to Flash memory. The system restarts
automatically, and the island is configured with this data.
If the configuration data is invalid, it is not used and the
island bus will stop.
If the configuration data was unprotected, the island bus
remains in edit mode. If the configuration data on the card
was password-protected (see p. 175), your island bus
enters protected mode at the end of the configuration
process.
Note: If you are using this procedure to reconfigure an
island bus and your island is in protected mode, you can
use the configuration software to change the island’s
operational mode to edit.
You can use a removable memory card to make a copy of your configuration data;
then use the card to configure multiple island buses. This capability is particularly
advantageous in a distributed manufacturing environment or for an OEM (original
equipment manufacturer).
Note: The island buses may be either new or previously configured, but the NIMs
must all run the same fieldbus protocol.
