PROTOCOL-SPECIFIC INFORMATION
9.9.6 Acyclic Data Access
Any inverter register can be accessed via PROFINET acyclic services. To accomplish this, set the API
to 0, Slot to 1, and SubSlot to 1. The record number/index value is equivalent to the desired register
number described in section 4.1. The length is specified according to the number of bytes to access.
Because each register corresponds to 2 bytes of data, the length must be an even number.
9.9.7 TIA Portal (STEP 7) Hardware Configuration Example
The following example will use TIA Portal V13 (STEP 7) to demonstrate the basic hardware
configuration procedure to configure a PROFINET device. The procedure, in general, will apply to
similar configuration software. The example will not cover all features of TIA Portal. Any questions
regarding TIA Portal (or similar configuration software) must be directed to the vendor of the software.
This example assumes that there is already an existing TIA Portal project with the desired PLC.
