+#### Schedule a Method in a message to be run several times
+
+Methods with their MethodArgs can be scheduled to be run any number of times. Meaning you can send the message once, and the method will be re-called at the interval specified with the **schedule** field. A max run time for the schedule must also be specified.
+
+`schedule : [int type value for interval in seconds, int type value for total run time in seconds]`
+
+**schedule** can also be used with messages specified in the **startup folder**.
+
+Example below will be run each 2nd seconds, with a total run of 5 seconds:
+
+```json
+[
+    {
+        "toNodes": ["central"],
+        "method": "REQCliCommand",
+        "methodArgs": [
