Область применения

CPU 1511T-1 PN:
for smaller applications with medium requirements on the program scope and processing speed, for distributed setup via PROFINET IO.
CPU 1515T-2 PN:
for applications with medium/high requirements on the program scope, networking and processing speed. For distributed configuration via PROFINET IO. The additional integrated PROFINET interface with separate IP address can be used, for example, for network separation, for connecting further PROFINET IO RT devices, or for high-speed communication as an I-Device.
CPU 1517T-3 PN/DP:
for applications with very high requirements regarding program scope, networking and processing speed. For distributed configuration via PROFINET IO and PROFIBUS DP. The additional integrated PROFINET interface with separate IP address can be used, for example, for network separation, for connecting further PROFINET IO RT devices, or for high-speed communication as an I-Device.
CPU 1517TF-3 PN/DP:
for standard and fail-safe applications with very high requirements regarding program scope, networking and processing speed. For distributed configuration via PROFINET IO and PROFIBUS DP with PROFIsafe. The additional integrated PROFINET interface with separate IP address can be used, for example, for network separation, for connecting further PROFINET IO RT devices, or for high-speed communication as an I-Device.

All SIMATIC S7-1500 CPUs support motion control functions. STEP 7 provides motion control instructions that are standardized in accordance with PLCopen for configuring and connecting a drive to the CPU.
Motion control with the S7-1500 supports the following technology objects:

Speed-controlled axes
Positioning axes
Synchronized axes (relative synchronism with synchronization, without specification of the synchronous position, setpoint linkage)
External encoders
Cams
Cam track
Probe

The technology CPUs of the SIMATIC S7-1500 offer advanced motion control functions:

Extended synchronous operation functions
- Synchronization with specification of the synchronous position
- Actual value linkage
- Shifting of the master value at following axis
- Camming
Cam disk
Up to 4 encoder or measuring systems as actual position for position control
