Product overview
2.2 Applications of the S7-1500 CPUs
Integrated Motion Control technology functions
All CPUs of the SIMATIC S7-1500 automation system support motion control technology
functions. STEP 7 provides PLCopen-standardized Motion Control instructions for configuring
and connecting a drive to the CPU.
S7-1500 Motion Control supports the following technology objects:
• Speed-controlled axis
• Positioning axis
• Synchronous axis
• External encoders
• Output cam
• Cam track
• Measuring input
Additional integrated technology functions
For effective commissioning, diagnostics and fast optimization of drives and controls, the
SIMATIC S7-1500 controller series offers extensive trace functions for all CPU tags.
In addition to drive integration, the SIMATIC S7-1500 controller series has a PID compact
closed-loop controller; easy-to-configure blocks allow automatic optimization of the
controller parameters for optimum control quality.
Other technology functions
Technology modules also implement functions such as high-speed counting, position
detection, measuring functions and pulse generators (PTO, PWM and frequency output). With
the CPU 1511C-1 PN and CPU 1512C-1 PN compact CPUs, these functions are already
integrated and can be implemented without additional technology modules.
SIWAREX is a versatile and flexible weighing module which you can use as a static scale for
operation.
Security Integrated
In conjunction with STEP 7, each CPU offers password-based know-how protection against
unauthorized reading out or modification of the program blocks.
Copy protection provides reliable protection against unauthorized reproduction of program
blocks. With copy protection, individual blocks on the SIMATIC memory card can be tied to its
serial number so that the block can only be run if the configured memory card is inserted into
the CPU.
In addition, you can assign various access rights to different user groups in the controller
using four different authorization levels.
Improved manipulation protection allows changed or unauthorized transfers of engineering
data to be detected by the controller.
The use of an Ethernet CP (CP 1543-1) provides you with additional access protection
through a firewall or possibilities to establish secure VPN connections.
