Bonjour,

Je n'ai pas de communication modbus RTU vis la configuration ci-dessus.
J'ai essayé les deux mode ch1 et ch2 mais rien ne fonctionne.

Avec le même programme, sur un FX3G + FX3G-CNV-BD + FX3U-485ADP-MB, çà fonctionne avec les registres D8400=H1097 (19200bauds, 8its, even), D8401=1(maitre).
Des idées, ou une solution.
Merci beaucoup.

Good morning,

I don't have modbus RTU communication with the above configuration.
I tried both ch1 and ch2 modes but nothing works.
With the same program, on an FX3G + FX3G-CNV-BD + FX3U-485ADP-MB, it works with registers D8400=H1097 (19200 bauds, 8its, even), D8401=1 (master).
Ideas, or a solution.
Thank you so much.

Gael.
