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).
2018-09-08 18:17:43 +02:00
0 means, the rule will only be called, if
the controller received a command from
2018-09-08 18:17:43 +02:00
another node, such as buttons.
2018-09-08 18:17:43 +02:00
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.
