Performance segments of compact CPUs
The compact CPUs can be used for smaller to medium-sized applications and have an
integrated analog and digital on-board I/O as well as integrated technology functions. The
following table shows the differences in performance between the two compact CPUs.

Supported technology functions
The CPUs of the SIMATIC S7-1500 family support Motion Control functions. STEP 7 (TIA
Portal) offers PLCopen standardized blocks 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 probes.
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 CPU tags.
In addition to drive integration, the SIMATIC S7-1500 has extensive closed-loop control
functions, such as easy-to-configure blocks for automatic optimization of the controller
parameters for optimized control quality.
Compact CPU 1511C-1 PN and CPU 1512C-1 PN CPUs support technology functions such
as fast counting, pulse generators (PWM, PTO and frequency output). Due to the supported
technology functions, the compact CPUs are suitable for controlling pumps, fans, mixers,
conveyor belts, lifting platforms, gate control systems, building management systems,
synchronized axes, etc.
SIWAREX is a versatile and flexible weighing module, which you can use as a static scale
for operation.
