PROTOCOL-SPECIFIC INFORMATION
9.2.4 Generic Class 1 I/O Produced and Consumed Data Settings
In the studio’s Project panel, add A7NETH-2P…Ethernet…EtherNet/IP Server…Produced I/O
Data…Produced Data Word and/or Consumed I/O Data…Consumed Data Word.
The Produced Data Word and Consumed Data Word objects are only applicable when connecting to
assembly instances 100 and 150 (generic I/O), which is typically the case. The Produced Data Word
defines the structure of status data sent from the inverter back to the controller. The Consumed Data
Word objects will define the structure of the command data sent from the EtherNet/IP controller (for
example, a ControlLogix PLC) to the inverter. These objects allow the creation of custom-built I/O data.
Up to 32 “command” register values can be sent to the inverter, and up to 32 “status” register values can
be sent back to the controller. Therefore, up to 32 Produced and 32 Consumed Data Word objects can
be created. If a consumed word offset is not defined, that data will be ignored by the inverter. If a
produce word offset is not defined, the value will default to 0. The size of the actual I/O produced and
consumed data is determined by the client upon initial connection establishment. Since a data word
utilizes 2 bytes, the size must be an even number of bytes. The I/O data format is summarized in Table
27.
Description
This 32-character (max) field is strictly for user reference: it is not used at any time by the driver.
Produced Data Word Offset
The value from the associated inverter register will populate this word offset of the produced data that is
to be sent to the client. It is recommend to start at word offset 0.
