Application
The CPU 1511C-1 PN is the entry-level CPU for applications with medium requirements for processing speed and speed of response in discrete production technology.

The CPU 1511C-1 PN has 5 analog inputs via which analog process signals, such as pressure or temperature, can be acquired. Of these, four inputs can be used for current or voltage measurement and one input for resistance test.
The analog outputs integrated directly on the CPU convert a 16-bit digital value into a current or a voltage and output this to the process. They are suitable for controlling proportional valves, for example.
By means of the 16 integrated digital inputs, 24 V DC signals from plant that can be recorded directly on the controller.
The 16 integrated digital outputs switch 24 V DC voltages and thus transfer internal signals from the controller to the plant.
The integrated counters offer the possibility of recording signals as fast as 100 kHz and evaluating the counter status or the current speed directly in the controller without the need for additional modules. The speed can be output as a frequency or period, or as a user-normalized speed.
The Motion Control functions of the CPU can use the counters as an actual position value and the analog outputs as a speed setpoint output. The 4 to 100 kHz outputs can be used to:

Directly control stepper motors
Output frequencies
or, via the PWM function:

Directly control valves or
Digitally transmit analog signals
In addition, the CPU offers comprehensive control functionalities via easy-to-configure blocks as well as the ability to connect drives via standardized PLC-open blocks.

The CPU 1511C-1 PN can be used as a PROFINET IO controller or as distributed intelligence (PROFINET I-Device). The integrated PROFINET IO IRT interface is designed as a 2-port switch so that a linear topology can be set up in the system.

each CPU is equipped with PROFINET IO IRT (2-port switch) as standard interface.
Integrated technology
Connection of analog and PROFIdrive-capable drives via standardized blocks (PLCopen).
Support of speed-controlled and positioning axes as well as external encoders, precise position gearing between axes, cams/cam tracks and probes.
Integrated I/O, e.g. for the direct operation of stepper motors and analog axes or for the direct recording of HTL encoders.
Design of the counter functions in the configuration and programming compatible with the TM Count 2x24V module.
Trace functions for all CPU tags, both for diagnostics in real time as well as for sporadic error detection; can also be called via the web server of the CPU.
Comprehensive control functionalities, e.g. easy to configure blocks for automatic optimization of the control parameters for maximum control performance.
Security Integrated
Password-based know-how protection against unauthorized read-out and modification of program blocks.
Copy protection for tying individual blocks to the serial number of the SIMATIC Memory Card: The block can only run if the configured memory card is inserted in the CPU.
4-level authorization concept:
Communication to the HMI devices can also be restricted.
Manipulation protection:
The controller recognizes changed or unauthorized transmissions of the engineering data.
Design and handling
Display of overview information:
E.g. Station name, plant identifier, location designation, etc., diagnostic information, module information, display settings.
Possible operations on the display:
Set addresses of the CPU or connected Ethernet communications processors, set date and time, select operating mode of CPU, reset CPU to factory settings, disable/enable display, activate protection levels, acknowledge messages, backup and restoring of the project.
Integrated system diagnostics
System diagnostics information is displayed consistently and in plain text in the display, TIA Portal, HMI devices and Web server, even for messages from the drives, and updated even if the CPU is in STOP mode.
Integrated into the firmware of the CPU, no special configuration is required
SIMATIC Memory Card (required for operation of the CPU)
Used as a plug-in load memory or for updating the firmware.
Also for storing additional documents or csv files (for recipes and archives)
Creation of data blocks for storage/reading of data via SFCs of the user program
Datalog (archives) and recipes
Storage of csv files for recipes and archives on the SIMATIC Memory Card;
easy access to plant-relevant operating data using Office tools or via a Web server
Easy access to machine configuration data by means of a Web browser or SD card reader (two-way data exchange from and to the controller)
Programming
Programming with STEP 7 Professional, V13 SP 1 UPD 4 or higher
Migration tool for upgrading from SIMATIC S7-300/S7-400 to S7-1500, converts the program code largely automatically. Non-convertible code is logged and can be manually adapted.
S7-1200 basic programs can be transferred to S7-1500 by copy-paste.
