Publication 2706-817
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
incompatible messages in the application.
If the terminal is changed
from:

MessageView 421F none
none
Note: The conversion will not take place (aborts) if these
incompatibilities exist. Each of the messages reported in the error
dialog must be edited individually before the application can be
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.
