Chapter 4 Plan to Use Your EtherNet/IP Adapter
Communication between the 1747-AENTR module and the I/O modules is
polled, similar to an SLC controller scan cycle. The adapter maintains a list of the
module ID for each slot, and handles electronic key validation during connection
requests, while processing ForwardOpen requests to the Connection Manager.
Software Requirements
RSLogix 5000 revision 20 or greater and RSLinx version 2.59 or greater are
required to configure the 1747-AENTR adapter. For more information on how
to configure your device, see
Configure the Adapter for Direct Connection
through the RSLogix 5000 or Logix Designer Application on page 27 .
Module Connections
The 1747-AENTR adapter supports module connections.
Module connection is performed in a deterministic and repeatable manner. This
connection allows a memory and Ethernet bandwidth efficient way to connect to
individual modules.
Each connection can be configured with the following connection types:
1. Exclusive Owner – specifies an independent connection where a single
device controls the output states in the target device. If you have an existing
Exclusive Owner connection to a target device, you cannot specify another
Exclusive Owner or Redundant connection to that same target device.
The 1747-AENTR adapter supports one Exclusive Owner connection per
SLC module.
2. Input Only – specifies an independent connection where a device receives
inputs from the target device and sends configuration data to the target
device. An Input Only connection does not send outputs; it only receives
inputs. You can specify multiple Input Only connections to the target
device from different originators.
The 1747-AENTR adapter supports up to five Input Only connections
per SLC module.
Listen Only – specifies a dependent connection where a device receives
inputs from the target device, but does not send configuration data with
the target device. A Listen Only connection only functions properly when
another non-Listen Only connection exists to the same target device. A
Listen Only connection does not send outputs; it only receives inputs. You
can specify multiple Listen Only connections to the target device from
IMPORTANT Logix Designer application (previously RSLogix 5000) revision 21 and
later supports direct connections to more than 13 slots.
