Overview of the 1734 POINT I/O EtherNet/IP Adapter Chapter 1
Before You Begin
To effectively use your adapter, note the following considerations.
Determine Compatibility
If using the adapter with a 1756-ENBT module or 1768-ENBT module, use the
following required firmware revisions for these bridge modules:
• 1756-ENBT firmware revision 4.006 or later
• 1768-ENBT firmware revision 2.003 or later
Understand Messaging
Class 3 (Explicit Message) requests through the 1734-AENT adapter to a specific
POINT I/O module may not always receive a response from the I/O modules. In
the case where the I/O module does not reply to the request, the adapter
responds with an error code indicating a timeout.
Configure Autobaud
The adapter cannot reconfigure an I/O module that you previously configured to
operate at a fixed communication 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 adapter.
Chapter Summary
In this chapter, you were introduced to the features of the POINT I/O Adapter,
and considerations for its installation and usage.
