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:
