6.2. Behaviour Statements
The GSM Commander is configured by defining a number of behaviour statements. Each
statement takes the form of an IF-THEN pair. You are thus able to select certain trigger
conditions that will cause desired actions to be performed. Any combination of IF and THEN
parts can be assembled into complete statements using the configuration software. The GSM
Commander can accept up to 128 separate behaviour statements, depending on the model .
One is also able to select time and input/output* constraints for any IF-THEN statement pair,
so that a statement will only be allowed to trigger at certain times of day, and on certain days
of the week or only if certain input/output conditions are met.
