This displays the EtherNet/IP Mapping Tool window.
The mapped tags (Data Attributes) appear on the left-hand side of the window.
The tags are highlighted in one of three colors:
 Tags that can be read from the IED are highlighted in yellow.
 Tags that can be written to the IED are highlighted in blue.
 Tags that are string data are highlighted in Brown. This includes tags from
Reports.
 Tags that come from GOOSE messages are highlighted in purple.
You must map tags to an output on the right-hand side. You must map the
available tags on the left-hand side to one of the three tabs on the right-hand side
of the window.
 Class 1 INPUTS is for tags that can be read from the IED (yellow, brown,
purple to Firefox). These are output on the gateway EtherNet/IP as Class 1
messages. For more on Class 1 inputs, see Specifications - EtherNet/IP on
page 80.
 Class 2 OUTPUTS is for tags that can be written to the IED (blue). Write tags
are highlighted in blue. These can be written by the PLC to EtherNet/IP on
the gateway as Class 1 messages.
 Class 3 MSGs is for any tag. In particular, if your application requires more
Data Attributes than the supported number of bytes that can be transferred by
EtherNet/IP Class 1 messaging, you must use Class 3 messages. These
must be explicitly read or written by the PLC using Class 3 messaging. For
more on Class 3 messages, see Specifications - EtherNet/IP on page 80.
