Depending on the SIMATIC product series and the backplane bus, the FCs have a different
suffix at the end of the block name:
● BasicTask_B
For S7-1500 CPU
● BasicTask_B
For S7-400 CPU
● BasicTask_X
For S7-300 PU with partyline
● BasicTask_P
For S7-300 CPU without partyline
For information on "Partyline", see Glossary.
For the block description, see section BasicTask_* FC (Page 255).
"BasicTask" label for three FCs
References to the respective FC are made in many places in the following sections. Since
the description of the different blocks usually applies to several SIMATIC product series, the
three FCs are referred to hereafter as "BasicTask". The FC version for the relevant CPU
type is meant in each context.
5.5 Structure of user program for TD7onCPU
5.5.1 The cyclic SINAUT program
Introduction
The structure of the TD7 blocks in the user program (OB1) is explained below.
The TD7 blocks must be proceeded in every OB1 cycle. Keep to the call sequence of the
blocks unless instructed otherwise.
Other user-specific parts of the program can be linked in before or after the TD7 blocks in
OB1 or, if practical, within the TD7 blocks.
You can structure the SINAUT-specific part in OB1 by calling it in lower-level FCs.
All data point typicals are FBs. An instance DB must be specified when an FB is called. The
number of this instance DB is identical to the object number of the data point object.
