Hi,
Im new to IoT and node-Red.
working step-by-step by this instructions link and still having an error:
[error] [modbus-flex-write:write Modbus payload] Error: Modbus exception 4: Slave device failure (device reports internal error)
could anyone please check are these instructions correct?
at the same time having also problems with MQTT.fx

2023-04-28 14:49:09,136 ERROR --- MqttFX ClientModel : Error when connecting
is it correct that according to Node red instruction the port is 1883 and in MQTT instruction using 8883?
Thank you very much
