If messages in the application before conversion consisted of
embedded Function keys or Entry variables, and the new designated
terminal type does not support these functions, the conversion
process will display an error dialog box.
The error dialog box reports the message numbers of any

Note: The conversion will not take place (aborts) if these

converted.
This section shows how to define runtime parameters for a
MessageView terminal and a PLC or SLC, that will communicate
over a Remote I/O (RIO) link.
The MessageView terminal operates as a single rack on the network.
Its RIO communication parameters are set to match those of the
logic controller it will exchange data with, while the application is
running.
MessageView terminals with RIO daughterboards are Catalog Nos.
2706-M1D1, -M1N1, and -M1F1.
