This AOI must be used in conjunction with an instance of a MESSAGE type instruction external to
the AOI. Create a Controller Tag of type MESSAGE, and create a Controller Tag of type
i550ExplicitMSGHandler (Figure 35).
Figure 35: Controller Tags for i550ExplicitMSGHandler
Insert the AOI into your ladder logic routine and assign the two tags created in Figure34 to the
i550ExplicitMSGHandler and MSG_Out fields. Configure all settings of the Message as shown
(Figure 36, Figure 37), and set the Source Element to the Value_Out parameter of the
i550ExplicitMSGHandler AOI (Figure 37). In this example, i550ExpMessageHandler_1.Value_Out is
selected. Please also select the i550 drive from the Communication tab of the Configuration window.
