5.6 LAU
Lauer Extension
The Lauer Extension is a new SCOM command specially developed for Beijer Elec-
tronics RBC. It extends the standard SCOM command set with more powerful func-
tions, which add special remote configuration, controlling and status capabilities to
each device.
The LAU command is a container for specific sub commands and their parameters.
They are encapsulated within the DATA field of the command stream. In contrast to
standard SCOM commands, a message returned in a response to Lauer Extension
command does not always contain the command itself. This means, a response mes-
sage may contain the same data for different commands. Therefore, a response mes-
sage should be processed immediately, after the command is sent.
The LAU command exposes the capabilities of a device model through SCOM.
While there is a base set of sub-commands, which are always supported on each de-
vice model, there are also sub-commands, which may expose the special capabilities
of a device, not available on other models.
The full LAU sub-command set is divided into three functional groups:
For any LAU sub-command, the following command and response streams are gen-
erally common:

CONTROL Intended to control a device or its hardware extensions, such as
