Examples:
A BASIC programme used to transfer values from the thermostat to the computer and to
display them specifying the channel number (e.g. 1 for IN_1, i.e. the bath temperature),
is as follows:
Note: set baud rate to 4800 (see Item 9.4.5)!
10 OPEN "COM1:4800,N,8,2" AS #1
20 CLS
30 LOCATE 8,5:PRINT SPC(20)
40 LOCATE 8,5
50 INPUT "Channel No.";NO$
60 PRINT #1;"IN_"+NO$
70 INPUT #1;A$
80 LOCATE 12,5:PRINT SPC(50)
90 LOCATE 12,5:PRINT "Response of the thermostat";A$
100 TI = TIMER+1
110 IF TI > TIMER THEN 110
120 GOTO 30
130 END
The isolation of the status data may be as follows:
LEFT $ (A$,1) = overtemperature fault
MID $ (A$,2,1) = low-level fault
MID $ (A$,3,1) = programme segment running
MID $ (A#,4,1) = control by T
