Acyclic Reading and Writing of Records

8.6.1

General

The ILD1900-x-IE with PROFINET can be parameterized via acyclic demand data that are not transmitted cyclically. These acyclic
requirements data are organized in PROFINET in the so-called records.
A record is a contiguous block
- of one or more parameters,
- which can be accessed in read or write mode.
When writing or reading a record, you must fill the read or write request with AR, API, slot, subslot, index, and the read/write length.
