Impossible de connecter plus de deux équipements sur le bus

[manuc0]

Bonjour,

J’ai un bus modbus avec 2 sondes respectivement ID1 et ID3, le bus est terminé aux extrémités par une résistance 120Ohms, j’utilise une clef usb/série RS 485 DSD TECH SH-U10 Convertisseur USB vers RS485 pour Modbus

Tout fonctionne lorsque un seul capteur est branché que ce soit le 1 ou le 3.

Lorsque j’utilise Modbus doctor avec exactement la même configuration 2 sonde tout fonctionne

Merci pour vos suggestions !!

[Michel_F]

Bonjour,

Les deux équipements utilisent la même connexion, or le convertisseur ne peut être utilisé que par un process.
Pas d’inquiétude, c’est prévu et il y a une solution très simple : un des 2 équipements doit utiliser la connexion de l’autre. Pour ça un des 2 équipements doit être paramétré avec le protocole de connexion Interface d'un autre équipement puis dans le second paramètre, il faut choisir l’équipement qui contient les paramètres de connexion. Sauvegarder et tout se met à fonctionner.
Sur le bus série, si un équipement MyModbus est défini par appareil, il ne peut y avoir qu’un seul équipement où la connexion utilise le port série, les autres équipements doivent utiliser sa connexion.

C’est expliqué dans la documentation.

edit : j’ai rajouté un chapitre qui parle de ce cas.

A+
Michel

[Michel_F]

Propositions d’optimisation :

1. Passer le Temps d'attente entre 2 requêtes de lecture à 0 et le monter de 0.1 s en cas d’erreur jusqu’à ce que la communication ne fasse plus d’erreur.
   NB : ceci ne sert plus à rien si le point 2 est mis en place.

2. Utiliser une plage de registres :
   2.1. Créer une nouvelle commande info de type plage de registres avec 256 [2] comme adresse de registre (2 registres à partir du 256, donc 256 et 257).
   2.2. Modifier les 2 commandes existantes de sorte d’utiliser cette plage de registres

→ Résultat : les 2 registres seront lus en une seule requête, le temps de cycle sera diminué. Le polling peut être diminué.

[manuc0]

Merci Michel les deux solution fonctionnent parfaitement !

Par contre je sèche sur le config des commandes pour ta proposition d’optimisation (2eme solution) Je crée une nouvelle cmd info S1-Niveaux → Fonction plage de registre, ou faut il définir le l’addresse esclave ?

Merci !

[Michel_F]

Cette commande doit avoir la fonction [0x03] Read holding registers avec le format plage de registres. Il faut sauvegarder comme ça pour que la commande soit « visible » et sélectionnable.

Ensuite il faut modifier les 2 commandes existantes avec la fonction Depuis une plage de registres et bien vérifier que la plage de registre sélectionnée est la bonne (comme il n’y en a qu’une, ça devrait la sélectionner tout seul), le reste reste inchangé.

edit: le principe de la plage de registres est expliqué dans la documentation, il ne faut pas hésiter à aller consulter la doc. Vraiment. J’ai passé du temps sur cette doc et je pense qu’elle est pas mal complète.

[manuc0]

Merci Michel ! C’est ok maintenant.

Bravo pour ta doc hyper complète (rien à voir avec la doc du plugin officiel ) et surtout ta réactivité.
Je te souhaite un excellent week end

[Michel_F]

Tu as remarqué une amélioration du temps de rafraichissement ? Ce serait bien de détailler ce point pour les lecteurs ou utilisateurs curieux. Ca dépend du matériel utilisé, mais ça peut convaincre des utilisateurs de passer le cap et de tester les plages de registres. Bon chez toi, il n’y a que 2 commandes info à optimiser, ça ne doit pas se voir beaucoup.

[manuc0]

Je crois que mes sondes ne sont pas compatible avec une lecture multiregistres

En effet, il semblerait bien que la réponse ne soit pas correctement formée.

Encore 2 choses :

• vous pouvez marquer la réponse qui vous convient comme étant la solution pour clore ce sujet
• vous pouvez éditer votre dernier message et déplacer la ligne qui contient les ``` juste en dessous de la dernière ligne de log pour que le message soit lisible avec la dernière capture. Je n’ai pas les droits pour éditer votre message, sinon je l’aurais fait pour vous.
