+## Description
+
+The MessageTrigger is a device design to poll regularly the attributes of TangoParser sub devices, and send a message to a TextTalker sub device if a change occured.
+
+It is possible to monitor several TangoParser devices with one MessageTrigger device. The configuration is done through the properties of the device:
+
+### MessageList property
+
+This property contains the list of attributes to monitor and the messages to send. This property is mandatory.
+
+```
+test/test/parser1/attribute1;Attribute 1 is true!;Attribute 1 is false!;
+test/test/parser1/attribute2;Attribute 2 is true!;Attribute 2 is false!;
+```
+
+### PollingPeriod property
+
+This property is the polling period of the monitoring, in ms. This property is not mandatory, default period is 1s.
+
+### TextTalkerProxyName
+
+This property should contain the address of the TextTalker device the message will be sent to. This property is mandatory.
