Modbus is connected via RS485. For communication to work you need to create a profile. Register addresses and formats can be found in the device documentation. See profile examples here: https://forum.logicmachine.net/showthread.php?tid=839

Configure RTU settings so they match your device settings. Then use Read test to check that communication works. You can use Excel profile generator to create JSON profile: https://forum.logicmachine.net/showthread.php?tid=3053

Hello, I need to enable Modbus on the same diesel generator APM303. But I can't read any values from it. Could you help me, have you activated it in some way (software or hardware on the generator itself)? Can you provide me with your profile for the generator for LM?

Hola, necesito habilitar Modbus en el mismo generador diesel APM303. Pero no puedo leer ningún valor de él. ¿Podrías ayudarme, lo has activado de alguna manera (software o hardware en el propio generador)? ¿Puede proporcionarme su perfil para el generador de LM?

Hola amigo, también he intentado leer los logs del APM303 sin éxito, ¿pudiste hacerlo?
