Configuring the Island Bus
890USE17700 April 2004 53
Using the STB XMP 4440 Optional Removable Memory Card to Configure the
Island Bus
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 Protecting Configuration Data, p. 164), 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:
z initial island bus configuration
z replace the current configuration data in Flash memory in order to:
z
apply custom configuration data to your island
z
temporarily implement an alternative configuration; for example, to replace an
island configuration used daily with one used to fulfill a special order
z
copying configuration data from one NIM to another, including from a failed NIM
to its replacement; the NIMs must run the same fieldbus protocol
z configuring multiple islands with the same configuration data
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:
z A new island is in edit mode.
z Edit mode is the default mode for a configuration downloaded from the Advantys
configuration software to the configuration memory area in the NIM.
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.
