Ansteuerung einer RS232 Schnittstelle
- Themenstarter vitlehm
- Beginndatum
So, habe jetzt die Daten für die Kommunikation für die RS 232 Schnittstelle erhalten. Leider nur auf Englisch.
3.1 Communication parameters
The serial communication is based on a standard RS232 communication.
The communication parameters are specified as follows:
• 9600 Baud
• 8 data bits
• No parity
• 1 stop bit
No hardware handshake is used.
3.2 Cable
The cable between the PC and the calibrator is designed in the following
way:
PC Calibrator
DB9 socket DB9 socket
CD 1 CD 1
RX 2 RX2
TX 3 TX 3
Gnd 5 Dnd 5
4 Telegrams
The communication always starts with the PC setting the calibrator in
communication mode (Log-on). At the same time any existing functions
are interrupted. As long as the calibrator is in communication
mode, the user interface is disconnected. This is shown by the text
"REMOT." in the display of the calibrator. It is only possible to read or
write when the calibrator is in remote mode.
When the PC logs off, the user interface of the calibrator is reactivated.

The slope rate is used by both on- and offline
switch test. The slope rate is only used
by the on-line switch test when the flag activated
in telegram #88 is set. In the on-line
switch test the slope rate is used when the
SET temperature command is activated. If
the activated SET temperature is lower than
the actual temperature the slope is negative.
A new SET temperatuer may be activated
before the current SET temperature is
accomplished. The slope rate is saved in
EEPROM

Tja - in welcher Sprache möchtes du denn Programmieren 
(was soll dat Programm eigendlich machen/können)
dir wird hier keiner das Programm schreiben aber helfen - beim schreiben dat geht
Ok mir ist noch die Sache mit dem Telegramm ein wenig unklar - aber damit kann man arbeiten
Eine Dauerüberwachung geht schon mal nicht:
"The communication always starts with the PC setting the calibrator in
communication mode (Log-on). At the same time any existing functions
are interrupted."
also genereller Ablauf:
communikation ein.
befehl senden
Communikation aus
ich erwähne noch mal meinen Hinweis Terminal (Hyperterminal) USB/RS232 Wandler und mal ein paar basics per Hand probieren..

Ich erkläre mal kurz die Situation:
Es sollen 3 Temperaturkalibratoren aufgestellt werden. Jeder Temperaturkalibrator hat eine bestimmte Starttemperatur und soll die Temperaturen automatisch nach Wunsch hochfahren und absenken .
Temperaturkalibrator1:
Start: 51°C eine gewisse Zeit halten bis ihm ein Befehl gesendet wird. > aufheizen auf 56°C, dann eine gewisse zeit die 56°C halten und dann wieder auf 51°C abkühlen und diese Temperatur halten bis der Vorgang von vorne beginnen kann: 51°C>56°C>51°C
Temperaturkalibrator2:
Start: 62°C eine gewisse Zeit halten, dann auf 65,5°C aufheizen, von 65,5°C auf 62°C runterkühlen und diese Temperatur halten, bis der Vorgang von vorne beginnt
Temperaturkalibrator3:
Start: 95°C eine gewisse Zeit halten, dann auf 98°C aufheizen, von 98°C auf 95°C runterkühlen und diese Temperatur halten, bis der Vorgang von neuem beginnt
Was bedeutet das, dass eine Dauerüberwachung nicht möglich ist?

Na wenn der rechner zugang zum Tauchbad hat ist die Bedienung am Tauchbad durch Menschen ausgeschlossen. Und das ist unschön - sach ich mal . also nur Kurze Kontaktaufnahme durch Rechner.
sprich bei deinem ersten Beispiel:
Communikation ein
setze Temp 51
Communikation aus
Schleife
warte eine Minute
Communikation ein
lese aktuelle Temp
Communikation aus
ist (gelesen <> 51) weiter schleife
schleife warte gewisse zeit
Communikation ein
setze Temp 56
Communikation aus
Schleife
warte eine Minute
Communikation ein
lese aktuelle Temp
Communikation aus
ist (gelesen <> 56) weiter schleife
schleife warte gewisse zeit
die grobe richtung
wenn du uns noch verräts in welcher Sprache du das Programieren möchtes -
Hardwareseite dürfte klar sein - nur zur Sprache: was darf es denn sein ? C,Java,Xbasic oder ****?
Wo kennste dich denn aus ?
Übrigends brauchste für jedes Tauchbad eine Rs232 Schnittstelle - das mal nur am Rande
In deinem Fall also 3 Schnittstellen
