Before You Begin

To effectively use your adapter, note the following considerations.

Determine Compatibility

RSLogix 5000 version 17 or greater must be used for the 1734-AENTR
Add-on Profile. The 1734-AENTR adapters will accept I/O
connections with the electronic keying for the 1734-AENT. This
allows the 1734-AENTR adapter to be used in a daisy-chain topology
with the 1734-AENT profile used for the 1734-AENTR.

If using the adapter with a 1756-ENBT module, 1768-ENBT module or
an L3xE processor, use the following required firmware versions for
these bridge modules:

• 1756-ENBT firmware version 4.5 or greater

• 1768-ENBT firmware version 2.1 or greater

• L3xE processor firmware version 17 or greater

If you use the BootP utility to assign IP addresses to the adapter, use
version 2.3.2 or greater.

Understand Messaging

Class 3 (Explicit Message) requests through the 1734-AENTR adapter
to a specific POINT I/O module do 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 time-out.

Establish I/O Connections

When you start 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.
