4 Interactions

GW-21 Configurator lets you define the interaction among subsystem. You can pro-

gram the gateway in order to send a message to a subsystem when it receives a

specific message from another subsystem.

4.1 The reaction message

The reaction message is triggered by the source message, and it is linked to it

through the reaction program number. The figure that follows shows the configuration

dialog box for the reaction message.

Fig. 4-1

The meaning of fields in the previous picture is as follows:

Description this is the text that describes the interaction on the reaction mes-

sage side. It could be for instance "Fire alarm Zone 1 Building 10"

Prog. no the sequential number used to identify the reaction

Len (Dec) is the number of byte in the source message . The configurator

checks that the number of bytes here specified equals the number

of bytes written in the Data fields below.

Long reaction this Boolean flag defines if the interaction is short or long. When the

interaction is long, the flag must be set ON.

Data (Hex) is the actual command as it is transferred on the line.

Subsystem # this the Line number (as defined on the Line dialog box) on the

GW21 connected to the subsystem you wish the reaction acts on
