MQTT2_Password Password to access the MQTT server.
Functional only for “mqtt” and “mqtts” types
MQTT2_Port MQTT server port.
For an MQTT server, the default port is 1883.
For an MQTTS secure server, the default port is
8883.
8883
MQTT2_QoS Guaranteed service number for sending
messages (Quality Of Service).
The possible values are:
•0: The message will be delivered at most once,
i.e. with no guarantee of reception.
•1: The message will be delivered at least once,
i.e. the concentrator will transmit several times
if necessary until the broker conrms that it has
been transmitted.
•2: The message will necessarily be saved by
the concentrator and will always send it as long
as the broker does not conrm its sending.
(avoids duplication of messages)
For “mqtts_gcloud”, “mqtts_azure”, and “mqtts_
aws” types, QoS 2 is not supported.
1
MQTT2_ResultTopic Name of the topic for the results of the
commands passed to the concentrator.
The MQTT2_ControlTopic parameter must be
populated for using commands.
If a topic name is entered, the concentrator
remains in permanent connection mode with the
MQTT server.
Works for all MQTT types except “mqtts_azure”
MQTT2_Timeout Maximum wait time in seconds for the response
from the MQTT server. If the server has not
responded within the allotted time, the send is
stopped and retried on the next schedule.
Functional only in QoS 1 or QoS 2.

MQTT2_TlsVersion TLS version supported by the MQTT server.
The possible values are:
•tlsv1.1: TLS in V1.1
•tlsv1.2: TLS in V1.2
Functional only for “mqtts” type
