Both the controller and the client GUI send their data as JSON Objects.
In JSON every Object is an unordered set of key/value pairs. The values of these pairs can be a JSON Object, a JSON Array or a primitive value (integer, string, boolean or null).
For more information or a complete grammar see http://www.json.org/.
...
- debug - true if the controller is set to verbose debug output, false otherwise
- cleanup - true after cleanup mode has been engaged, false before that point
- pause - true while the controller is paused, false otherwisewrite - true if receiving client has write access, false otherwise
- trainCount - an integer with the number of active trains on the railway
- trains - a JSON Array with the data of all trains, each entry is a JSON Object with these values
- trainNum - the individual controller number of the train
- waiting - boolean value, true if the train is waiting in a station, false otherwise
Status colour Red state - integer value for current train state (0 = travelling, 1 = waiting, 2 = travelling until next station, 3 = forced wait, 4 = no schedule)title Removed - waitTime - (integer) remaining milliseconds until departure (0 if not waiting)
Status colour Yellow spdSlow - the integer PWM value of this train while driving slowtitle changed - spdCaution - the integer PWM value of this train while driving caution
- spdNormal - the integer PWM value of this train while driving normally
- stationTimes - a flat array of the form [station1_minTime, station1_maxTime, station2_minTime, station2_maxTime, ...]. The order of the stations is defined by the order in the table below but the KH (reverse) tracks are omitted.
- currentIndex - an integer describing the current position in the schedule
schedule - a JSON Array of integer values, representing the station tracks, encoded in the following fashion
Status currentDestination - the current destination track, encoded in the following fashioncolour Yellow title CHANGED Number Track Number Track Number Track Number Track 9 KH_ST_1 17 KH_ST_1 (reverse) 25 IC_ST_1 33 OC_ST_1 10 KH_ST_2 18 KH_ST_2 (reverse) 26 IC_ST_2 34 OC_ST_2 11 KH_ST_3 19 KH_ST_3 (reverse) 27 IC_ST_3 35 OC_ST_3 12 KH_ST_4 20 KH_ST_4 (reverse) 13 KH_ST_5 21 KH_ST_5 (reverse)
- locks - a JSON Array containing the current value of the track permissions, ordered by the default encoding (Hoermann API)
- tickTime - Time consumption of tick function in milliseconds. 3 element double-array [min,avg,max].
- overallTime - Time consumption of overall controller loop in milliseconds. 3 element double-array [min,avg,max].

Messages received by controller
- Every message must contain the key keys command and data.
- Valid values for command are the following uppercase commands.
- Depending on the command, additional keys might be requiredthe data-object contains the described infos.
- If a command doesn't require any additional information, the data-object may be omitted or empty.
Valid commands
- STATUS - Poll for the current status, should trigger a status reply message
- SHUTDOWN - Causing the controller to end the program and close all sockets

- state - boolean value, true if lights should be lit
- WAIT (write) - Force a train to wait in the next station, must supply additional payload
- train - integer train identification
- START (write) - Force a waiting train to immediately abort the waiting timer, must supply additional payload
- train - integer train identification
