5.5 Structure of user program for TD7onCPU

TIM 1531 IRC

134 Operating Instructions, 02/2018, C79000-G8976-C468-02

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.
