Acyclic data exchange

S7 has system function blocks for writing / reading this data. The following data is transferred
for addressing:
Index
ID
Length
Note
The following applies for PROFIBUS DP:
The following datasets can be used via the C1 channel only, depending on the application.
10.2.1

Acyclic output data

Dataset 100 "field type 1"
Byte
0,1
2,3
...
124,125
126,127
Using this dataset, fields of type 1 can be defined. This field type comprises one channel
range that is described by the first and last channel of the field.
Application range: Thermoforming, clustering of adjacent channels
Definition is via an array [1..32] with two elements of type "Word". Up to 32 fields can be
defined.
The field number corresponds to the array index.
Field number 0 cannot be used. It exists automatically in the HCS and contains all the
channels of the HCS by default. Production and standby setpoints are preset to 100 %.
All channels that are not explicitly assigned to a new field remain in this default field.
To use fields, the user must ensure that all the existing channels are assigned to a user field.
A field can be erased by entering a 0 for the number of the start channel and the end
channel.

Data record number
Logical address of the PROFINET/PROFIBUS component
For the datasets described below, the logical address is always the diagnostics address
from the hardware configuration.
When writing: Length of the data in the dataset
•
When reading: Maximum number of data items that can be received simultaneously.
