Es ist der Master, der entscheidet, welcher Slave agiert und auf den vom Master gesendeten Befehl reagiert. Aber mit diesem neuen Ger\u00e4t von ICPDAS, der tSH-730-Serie, ist es jetzt m\u00f6glich, zwei Master gleichzeitig zu haben.<\/p>\n<p>Die beiden Master k\u00f6nnen mit denselben Slaves kommunizieren, z. B. wenn Sie an jedem Ende eines Raumes ein Kontrolldisplay haben, das die Beleuchtung oder etwas anderes steuert. Es k\u00f6nnte auch sein, dass Master 2 als Backup l\u00e4uft, wenn also Master 1 ausf\u00e4llt, \u00fcbernimmt Master 2.<\/p>\n<p>Eine andere Anwendung k\u00f6nnte sein, dass Sie zwei Master und mehrere Slaves haben, aber dasselbe RS-485-Netzwerk verwenden wollen, das Sie verdrahtet haben. Ein Master wird dann so eingerichtet, dass er mit ausgew\u00e4hlten Slaves kommuniziert, der andere Master wird so eingerichtet, dass er mit den anderen Slaves kommuniziert.<\/p>\n<p>&nbsp;<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-1216\" src=\"https:\/\/thiim.com\/wp-content\/uploads\/tSH-735_3.gif\" alt=\"\" width=\"476\" height=\"223\" \/><\/p>\n<p><strong>Aber wie?<\/strong><\/p>\n<p>Wenn zwei Master normalerweise gleichzeitig \u00fcber dieselbe Verbindung kommunizieren, gehen Daten verloren. Daher brauchen wir einen Puffer, und genau das ist unsere tSH-730-Serie. In der obigen Abbildung gibt es zwei Master, Master 1 sendet rote Pakete und Master 2 sendet gr\u00fcne Pakete.<\/p>\n<p>Wenn Master 1 ein rotes Paket sendet, wird es an die Salvos weitergeleitet, der ausgew\u00e4hlte Slave antwortet und die Antwort wird an Master 1 gesendet. Gleiches gilt f\u00fcr Master 2.<\/p>\n<p>Wenn aber Master 1 und Master 2 gleichzeitig Daten senden, m\u00fcssen wir ein Signal verz\u00f6gern. Im obigen Beispiel wird das rote Paket an die Slaves gesendet, w\u00e4hrend das gr\u00fcne Paket einen Moment lang gespeichert wird.<\/p>\n<p>Die Antwort auf das rote Paket wird an Master 1 zur\u00fcckgeschickt, dann kann das gr\u00fcne gespeicherte Paket an die Slaves und die Antwort darauf an Master 2 zur\u00fcckgeschickt werden, ohne dass jemand etwas merkt.<\/p>\n<p>Hinweis: Es ist jedoch wichtig, dass Sie in den beiden Mastern ein l\u00e4ngeres Antwort-Timeout einstellen k\u00f6nnen, da die Antworten verz\u00f6gert werden k\u00f6nnen, w\u00e4hrend sie darauf warten, den Konverter zu durchlaufen. Es ist auch wichtig, dass Master 1 und Master 2 nicht die Bandbreite des 100% verwenden, es muss Platz f\u00fcr beide gleichzeitig sein.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-1217\" src=\"https:\/\/thiim.com\/wp-content\/uploads\/tSH-735_4.jpg\" alt=\"\" width=\"570\" height=\"710\" srcset=\"https:\/\/thiim.com\/wp-content\/uploads\/tSH-735_4.jpg 570w, https:\/\/thiim.com\/wp-content\/uploads\/tSH-735_4-241x300.jpg 241w\" sizes=\"(max-width: 570px) 100vw, 570px\" \/><\/p>\n<p><strong>Modbus\/RTU, Modbus\/TCP, DCON oder Ihr eigenes Protokoll.<\/strong><\/p>\n<p>Alle Slaves m\u00fcssen mit der gleichen Geschwindigkeit laufen, aber die beiden Master k\u00f6nnen mit unterschiedlichen Geschwindigkeiten laufen und m\u00fcssen nicht die gleiche Geschwindigkeit wie die Slaves haben.<\/p>\n<p>W\u00e4hrend der Konfiguration des Moduls, die einfach \u00fcber den eingebauten Ethernet-Anschluss erfolgt, w\u00e4hlen Sie zun\u00e4chst aus, welches Protokoll und welche Geschwindigkeit Master 1, dann Master 2 und schlie\u00dflich die Slaves verwenden sollen.
