Note
If you want to change the STEP 7 user interface to English (in the SIMATIC Manager,
Options/Settings menu), the following applies depending on the version of the SINAUT
configuration tool:
• SINAUT configuration tool version < 2.0
The
Mnemonic option must not be changed to IEC or English! This must remain set to
SIMATIC. Otherwise there will be compilation errors when generating the SINAUT
program!
• SINAUT configuration tool as of version 2.0
The
Mnemonic option can be changed to IEC or English! The configuration tool checks
the setting for Mnemonic and compiles the SINAUT program correctly.
Basic structure of the user program
The SINAUT user program consists of the following:
● Startup program OB100
Here, only the startup block for ST7 "FC Startup" needs to be called. It does not require
any parameters.
● Cyclic program OB1
In the simplest case, this program consists of the basic block "FC BasicTask". Following
this, the user calls all the data point typicals required for the CPU and sets the
parameters to suit the particular application.
● Time-driven program OB35 (or another cyclic interrupt OB)
This program is required only when counted pulses need to be acquired on the CPU. FC
PulseCounter is called once or more than once in the cyclic interrupt OB.
