a)  Double-click on the XIO element located to the left of the MSG block.  

In the drop-down box, double-click on the “connection.EN” field.  Refer 
to Figure 81.  This configuration causes the MSG instruction to 
automatically retrigger itself when it completes.  While this is 
acceptable for the purposes of this example, it can produce high 
network utilization.  In actual practice, it may be desirable to 
incorporate additional logic elements to allow triggering the MSG 
instruction at a specific rate or under specific conditions.
