西门子SIMATICS7-1500T-CPU

The S7-1500C CPUs are based on the modular controllers of the SIMATIC S7-1500 series and offer additional digital and analog inputs and outputs directly on the CPU. Just like the modular CPUs of the SIMATIC S7-1500 series, the compact SIMATIC S7-1500 controllers can be expanded with modules that are 25 mm or 35 mm wide.

 

Product description CPU 1511C-1PN and CPU 1512C-1 PN:

The 1511C-1 PN and 1512C-1 PN CPUs are suitable for applications in series and special-purpose machine manufacturing with mid-range requirements for program size and processing speed.

The 1511C-1PN and 1512C-1 PN CPUs can be used as PROFINET IO controllers or as distributed intelligence (PROFINET I-device). The integrated PROFINET IO IRT interface supports isochronous mode and is designed as a 2-port switch, enabling a linear topology to be configured in the system.

Integrated digital and analog inputs/outputs on the CPU permit direct connection to the process. Both CPUs, CPU 1511C-1 PN and CPU 1512C-1 PN, have 5 analog inputs that can be used to detect analog process **s such as pressure or temperature. 4 of the 5 integrated analog inputs can be used for current or voltage measurement and one input for a resistance test. The two analog outputs integrated directly on the CPU convert a 16-bit digital value into a current or a voltage and output this value to the process. They are suitable, for example, for controlling proportional valves.

The digital inputs can be used to detect 24 V DC **s from the system directly on the controller. The integrated counters can detect fast **s up to 100 kHz and evaluate the counter reading or the current velocity without additional modules directly in the controller. The velocity can be output as frequency, period or as velocity standardized by the user.
The integrated digital outputs operate 24 V DC voltages and thus forward internal **s from the controller to the system.
Each high speed counter can be assigned a digital output. Integrated comparators permit fast responses depending on the counter reading.
The motion control functions of the CPU can use the integrated counters as position actual value and the analog outputs as speed setpoint output.

The front connector for the integrated I/O is the push-in connector that is used for the 25 mm wide input and output modules (89257659). These front connectors are included in the product package of the CPU 1511C-1 PN or the CPU 1512C-1 PN and do not have to be ordered separately.

The compact controllers in the product range of the SIMATIC S7-1500 series of controllers offer the following highlights:

• Open Ethernet communication (TCP/IP, UDP, ISO-on-TCP)
• Web server functionality for information, status and diagnostics
• Option handling for distributed configuration as well as option handling in the network

• Security Integrated
• Integrated system diagnostics
• Integrated technology
• Trace function

 

 

Option handling for distributed configuration and in the network
As all SIMATIC S7-1500 controllers, the compact CPUs offerconfiguration control (option handling) to configure the maximum configuration of a controllerand to operate any versions (options) that deviate from this configuration.
Users can vary the central configuration using the configuration control as long as the actual configuration can be derived from the configured configuration of a maximum configuration.

 

SIMATIC Memory Card (required for operating the CPU):
As all S7-1500 CPUs, the compact controllers work with a SIMATIC Memory Card. It is used as a plug-in load memory or for updating the firmware.
In addition to the STEP 7 project including comments and symbols, additional documentation or csv files (for recipes and archives) can also be stored on the SIMATIC memory card. Data blocks can be created and data stored or read via SFCs on the SIMATIC memory card with the user program.
