The Produced Data Word and Consumed Data Word objects are only applicable when using the I/O
module “IN: 32 WORDS, OUT: 32 WORDS”, which is typically the case. The Produced Data Word
defines the structure of status data sent from the inverter to the controller. The Consumed Data Word
objects will define the structure of the command data sent from the controller (for example, a Siemens
PLC) to the inverter. These objects allow the creation of custom-built I/O data. Up to 32 “command”
function code values can be sent to the inverter, and up to 32 “status” function code 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 PROFINET controller. The I/O data format is summarized in Table 36.
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 function code will populate this word offset of the produced data
that is to be sent to the controller. It is recommended to start at word offset 0.
Consumed Data Word Offset
The consumed data received from the controller at this word offset will contain the value to be written to
the associated inverter function code. It is recommended to start at word offset 0.
Function Code
The inverter function code (refer to section 4) associated with the word offset. For the Produced Data
Word object, enter a “status” function code to be monitored. For the Consumed Data Word object, enter
a “command” function code that can be written.
Data Type
Each data word is fixed to 16-Bit Unsigned (equivalent to two bytes.) The data word is transferred in little
endian format.

The default I/O configuration is described in Table 37.
Always use the studio to confirm the configuration before commissioning the device.
