Chapter 1 Overview of the 1734 POINT I/O EtherNet/IP Adapter

Important Adapter

Considerations

Before you begin using your adapter, note the following important

considerations.

Set the

Chassis Size

The I/O adapters for EtherNet/IP require configuration of their chassis size

before you can make any I/O connections. The factory default setting for the

chassis size is one slot, which represents the adapter by itself.

You must set the chassis size to a number equaling one slot for the adapter plus

one slot for each I/O module present in the backplane of the adapter.

For example, a POINT I/O system consisting of a 1734-AENT adapter, one

1734-IB8, one 1734-OB8, and one 1734-OB8S POINT Guard I/O module uses

a chassis size of 4. The adapter stores this chassis size setting in non-volatile

memory.

Each time the adapter is powered up, the adapter compares the number of I/O

modules present on its backplane to the chassis size value from non-volatile

memory. The adapter does not allow any I/O connection until the number of

I/O modules present equals the chassis size value minus one for the adapter itself.

ATTENTION: You must only use Series C and above POINT I/O modules

with 1734-AENT EtherNet/IP Adapters. Series A or Series B POINT I/O

modules do not work with 1734-AENT EtherNet/IP Adapters (does not

apply to POINTGuard modules).
