System environment for a Compact CPU
The Compact CPUs can be used in the following system environments:
Application scenarios
Components required
Configuration software
In the user program
Central operation with a
S7-1500 Compact CPU
• S7-1500 automation
system
• Compact CPU
STEP 7 (TIA Portal):
Operating with "Counting
and measurement" technol-
ogy object
• Device configuration with
hardware configuration
• Parameter settings with
High_Speed_Counter
technology object
Counting and measuring
functions:
High_Speed_Counter in-
struction for the technology
object
STEP 7 (TIA Portal):
Position input for "Mo-
tion Control" technology
object
• Device configuration with
hardware configuration
• Parameter setting with
axis technology object
Instructions for "Motion Con-
trol" technology object
STEP 7 (TIA Portal):
Manual operation (without
technology object)
• Device configuration and
parameter setting with
hardware configuration
Direct access to control and
feedback interface of the
technology module in the I/O
data
Parameter assignment options
In an S7-1500 system, you have two options for parameter assignment and control of
technology module functions:
● Configuration using the technology object and control using the associated instruction
Access to the control and feedback interface of the technology module takes place
through the technology object.
● Parameter setting via hardware configuration
The control and feedback interface of the technology module is accessed using direct
access to the I/O data.
