Product overview
2.2 Applications of the S7-1500 CPU
Performance segments of compact CPUs
The compact CPUs can be used for smaller to mid-range applications and have an
integrated analog and digital on-board I/O as well as integrated technology functions. The
following table shows the specific properties of the Compact CPUs.

Integrated technological functions
The CPUs of the SIMATIC S7-1500 support motion control functions. STEP 7 offers blocks
standardized according to PLCopen for configuring and connecting a drive to the CPU.
Motion Control supports speed-controlled, positioning and synchronous axes (synchronizing
without specification of the synchronous position) as well as external encoders, cams, cam
tracks and measuring inputs.
The CPUs of theSIMATIC S7-1500T support advanced motion control functions in addition
to the motion control functions offered by the standard CPUs. Additional motion control
functions are absolute synchronous axes (synchronization with specification of synchronous
position) and the cam.
For effective commissioning, diagnostics and fast optimization of drives and controls, the
SIMATIC S7-1500 controller family offers extensive trace functions for all CPU tags.
In addition to drive integration, the SIMATIC S7-1500 has a PID compact closed-loop
controller; easy-to-configure blocks allow automatic optimization of the controller parameters
for optimized control quality.
Technology modules also implement functions such as high-speed counting, position
detection and measuring functions and pulse generators (PWM and frequency output). In
compact CPU 1511C-1 PN and CPU 1512C-1 PN CPUs, these functions are already
integrated and require no additional technology modules.
SIWAREX is a versatile and flexible weighing module, which you can use as a static scale
for operation.
Due to the supported technology functions, the CPUs are suitable for controlling pumps,
fans, mixers, conveyor belts, lifting platforms, gate control systems, building management
systems, synchronized axes, etc.
