Preconfiguration "MQTT Server - Receiving and processing data sent by publish client - Communication set with data and panel"
Configuration of the
MQTT communication. This preconfiguration allows to receive and process data sent by the client of the
publish type. This is done directly into the application without the need to use
MQTT broker.
This preconfiguration can be activated when creating a new object (e.g. by
"New object ..." in the local object menu or by pressing the
Insert key after selecting the object) and is included in the group:
"/ Communication / Protocols and other communications / MQTT".
This preconfiguration can be created in the object:
PmaFolder or
PmaRoot.
The preconfiguration creates an object of the
PmaFolder type with objects
PmaComm,
PmaData,
PmaPanel and
PmaTimer.
MQTT_Server -
PmaFolder
Main object configured as communication driver of the service. The
PmaFolder object has the method
OnPublish that is used for data receipt and processing.
The
PmaComm object is configured by the
PmChar protocol. It has two
PmaCommMsg subobjects configured as
Slave (for message receipt). Methods and events of these objects provide communication functionality.
The
PmaTimer object checks whether the logged in client maintains connection.
Test -
PmaFolder The folder contains testing panel "
TestPanel" and auxiliary
PmaData object. The panel serves for testing and viewing the received data.
These configurators can be set before the preconfiguration is created:
| The name of created object | Name of the object created in the Pma objects tree. The maximum name length is 30 characters. This is a system name, so it must contain only alphanumeric and must not contain any diacritics (i.e. national dependent characters), empty string, spaces and the first character must not be a number.
