应用

The CPU 1511-1 PN is the cost-effective entry-level CPU for standard and fail-safe applications with medium requirements for processing speed and speed of response in discrete production technology. With its RAM size, this CPU is also suitable for medium-sized applications. It can be used as a PROFINET IO controller or as distributed intelligence (PROFINET I-Device). The integrated PROFINET IO IRT interface is designed as 2-port switch so that a linear topology can be set up in the system. 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.

设计

The CPU 1511F-1 PN has:

a powerful processor:

The CPU achieves a command execution time as low as 60ns per binary command.

extensive RAM:

230 KB for program, 1 MB for data

SIMATIC memory cards as load memory;

permit additional functions such as datalog and archives

Flexible expansion possibilities: single-tier configuration with max. 32 modules (CPU + 31 modules)

Display with functions for the

Display of overview information such as station name, higher level designation, location designation, etc.

Display of diagnostic information

Display of module information

Display of display settings

Setting of IP addresses

Setting of date and time

Selection of the operating mode

Resetting of the CPU to factory settings

Disabling/enabling of the display,

Enabling of protection levels

display of safety mode, overall signature and date of the last download with signature change.

PROFINET IO IRT interface for connecting distributed I/O via PROFINET

Supports PROFIsafe in centralized and distributed configuration

功能Performance

Faster command processing, depending on the CPU type, language extensions and new data types

Even shorter response times of the CPUs due to considerably faster backplane bus

Powerful network connection:

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

Trace functions for all CPU variables, both for diagnostics in real time as well as for sporadic error detection

Comprehensive control functionalities, e.g. easily configurable blocks for automatic optimization of the control parameters for optimum control quality

Security Integrated

Password-based know-how protection against unauthorized reading 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 into 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 the overview information:

e.g. station name, plant identifier, location designation, etc., diagnostic information, module information, display settings.

Possible operations on the display:

set addresses, set date and time, select operating mode of CPU, reset CPU to factory settings, disable/enable display, activate protection levels.

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 in the firmware of the CPU, no special configuration is required
