Note: In IEC 61131-3 compatible systems function blocks are
provided for accessing data non-cyclically. In Siemens S7, SFB 52
"RDREC" can be used for reading and SFB53 "WRREC" for
writing Data Records.
For more information on above function blocks, see document
Communication Function Blocks for PROFIBUS DP and
PROFINET IO v2.0 available at www.profibus.com
.
Supported Record Data Objects and their indices are listed in the
table below.
Table 12.Record Data Objects
Base Mode Parameter Access - Local
The DO-ID field in the Record Data Object request header is not
evaluated by the parameter manager and a valid Parameter
Access Point (PAP) should be used to access record data. The
PAP is located in subslot 1 of the slot 1.
Base Mode Parameter Access - Global
The slot and subslot fields in the Record Data Object request
header are not evaluated by the parameter manager. The DO-ID
is used instead and it should have either value 0x00 or 0x01.
