|
|
Control other nodes by means of rules like:
|
|
IF <condition> THEN <action>
|
|
|
|
These rules allow to execute actions based on conditions.
|
|
Examples for conditions are:
|
|
- the Player Detector detects a player
|
|
- a button is pressed
|
|
- a node state is fault, blocked, standby,...
|
|
|
|
Actions are:
|
|
- switch on/off tubelib nodes, like lamps, machines
|
|
- send chat messages to the owner
|
|
- output a text message to the display
|
|
|
|
The controller executes all rules cyclically.
|
|
The cycle time for each rule is configurable
|
|
(1..1000 sec).
|
|
0 means, the rule will only be called, if
|
|
the controller received a command from
|
|
another node, such as buttons.
|
|
|
|
Actions can be delayed. Therefore, the
|
|
'after' value can be set (0..1000 sec).
|
|
|
|
Edit command examples:
|
|
- 'x 1 8' exchange rows 1 with row 8
|
|
- 'c 1 2' copy row 1 to 2
|
|
- 'd 3' delete row 3
|
|
|
|
The 'outp' tab is for debugging outputs via 'print'
|
|
The 'notes' tab for your notes.
|
|
|
|
The controller needs battery power to work.
|
|
The battery pack has to be placed near the
|
|
controller (1 node distance).
|
|
The needed battery power is directly dependent
|
|
on the CPU time the controller consumes.
|
