Frequency output Up to 100 kHz Up to 100 kHzAll CPUs of SIMATIC support Motion Control technology functions. STEP 7 offers
Motion Control instructions standardized according to PLCopen for configuring and
connecting a drive to the CPU.
Motion Control supports the following technology objects:
● Speed-controlled axes
● Positioning axes
● Synchronous axes
● External encoders
● Output cams
● Cam tracks
● Measuring inputs
The technology CPUs of the SIMATIC offer enhanced Motion Control functions:
● Advanced synchronization functions
– Synchronization with specification of the synchronous position
– Actual value coupling
– Shifting of the master value at following axis
– Camming
● Up to 4 encoders or measuring systems as actual position for position control
The technology CPUs of the SIMATIC additionally support the following technology
objects: – Cam – Kinematics
● Cam
● Kinematics
● Controlling of kinematics, such as
– Cartesian portals
– Roller pickers
– Delta pickers
– SCARA
Due to the supported technology functions, the T CPUs are suitable for controlling
packaging machines, converting applications, assembly automation, etc.
Additional integrated technology functions
For effective commissioning, diagnostics and fast optimization of drives and controls, the
SIMATIC controller family offers extensive trace functions for all CPU tags.
In addition to drive integration, the SIMATIC has a PID compact closed-loop
controller; easy-to-configure blocks allow automatic optimization of the controller parameters
for optimized control qualitydetection, measuring functions and pulse generators (PTO, PWM and frequency output). For
compact CPU 1511C-1 PN and CPU 1512C-1 PN 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
operationdetection, measuring functions and pulse generators (PTO, PWM and frequency output). For
compact CPU 1511C-1 PN and CPU 1512C-1 PN CPUs, these functions are already
integrated and can be implemented without additional technology modules.

operationAll CPUs of the SIMATIC product series feature a display with plain text
information. The display provides the user with information on the order numbers, firmware
version, and serial number of all connected modules. In addition, the address of the CPU
and other network settings can be adapted locally without a programming device. Error
messages are immediately shown on the display in plain text. In the case of servicing, plant
downtimes are minimized by quick access to diagnostics alarms. Detailed information about
this and a multitude of other display functions is available in the SIMATIC Display Uniform front connectors for all modules and integrated potential jumpers for flexible
formation of potential groups simplifies storage. Additional components such as circuit
breakers, relays, etc., can be installed quickly and easily, since a DIN rail is implemented in
the rail of the . The CPUs of the SIMATIC product series can be expanded
centrally and modularly with signal modules. Space-saving expansion enables flexible
adaptation to each application.
The system cabling for digital signal modules enables fast and clear connection to sensors
and actuators from the field (fully modular connection consisting of front connector modules,
connection cables and I/O modules), as well as simple wiring inside the control cabinet
(flexible connection consisting of front connectors with assembled single cores).
System diagnostics and alarms
Integrated system diagnostics is enabled by default for the CPUs. The different types of
diagnostics are configured instead of programmed. System diagnostics information is shown
