Before You Begin
To effectively use your adapter, note the following considerations.
Understand Messaging
Class 3 (Explicit Message) requests through the 1734-ACNR adapter to
a specific POINT I/O module may not always receive a response
from the I/O module. In the case where the I/O module does not
reply to the request, the adapter responds with an error code
indicating a time-out.
Establish I/O Connections
When you power up a POINT I/O system and establish I/O
connections, the outputs transition to the Idle state, applying Idle
state data before going to RUN mode. This occurs even when the
controller making the connection is already in RUN mode.
Configure Autobaud
The adapter cannot reconfigure an I/O module that you previously
configured to operate at a fixed baud rate. When you reuse a POINT
I/O module from another POINT I/O system, configure the module
to autobaud before using it with the 1734-ACNR adapter.
