EtherNet/IP configuration
The “EtherNet/IP Configuration” page sets how the Raw/ASCII data is transmitted to an
EtherNet/IP controller.

EtherNet/IP interface configuration
PLC type:
The GW EIP/ASCII... provides EtherNet/IP connectivity to the entire
ControlLogix family of PLCs as well as the SLC, PLC-5, and MicroLogix PLCs. The
ControlLogix setting supports full CIP interfaces including Class 1, Write to Tag and full
object interface support. The ControlLogix PLC family of PLCs includes the Rockwell
®
ControlLogix
®
, FlexLogix, MicroLogix, SoftLogix and other advanced PLCs. This selection
also supports numerous PLCs manufactured by other manufacturers, such Omron
®
and
Schneider Electric
®
. The MicroLogix setting provides support for Rockwell MicroLogix,
SLC and PLC-5 PLCs. These PLCs only support a limited EtherNet/IP interface that does
not include Class 1 or full object support. Only Write to File and communication using PCCC
MSG instructions is provided.
Transfer mode to PLC:
Specifies how the Raw/ASCII data will be transferred (via
EtherNet/IP) to the PLC.
–
When
Write to Tag/File
is selected, the GW EIP/ASCII... writes the serial data directly
into a tag or file on the PLC. This option should only be used if the PLC can scan and
consume the serial data faster than the serial device can produce it.
–
When
Class 1
is selected, the GW EIP/ASCII... writes the serial data into a tag or file
on the PLC and provides a mechanism to synchronize the data flow between the PLC
and the GW EIP/ASCII.... Use this method when you want to ensure that the tag or file
is not overwritten before the PLC can consume the data. Class 1 communication is only
applicable to ControlLogix PLCs.
–
Select
Polling
if the PLC will request data on a periodic basis. It provides the ability to
control the received data flow. However, it does require periodic data requests and the
request rate must be fast enough to ensure that the serial port RX queues on the
GW EIP/ASCII... do not overflow.
The default is
Class 1
.
