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.
8.6.2 I&M Records
PROFINET defines so-called Identification and Maintenance Records, which contain various device information. These
records are available in every PROFINET device.
The read and write request is addressed as follows:
Parameter Length in bytes
AR 0
API 4
Slot 2
Subslot 2
Index 2
Length 4
The ILD1900-x-IE with PROFINET supports the I&M records 0 to 3.
