SIMATIC S7-1500

Design

General

An S7-1500 automation system has a modular design and comprises up to 32 modules. It has a comprehensive range of modules that can be combined individually. The S7-1500 automation system supports one-tier configurations where all modules are mounted on one DIN rail (see Manual for requirements).

A system includes the following:

  • Controller:
    CPUs with different grades of performance with integrated PROFINET interface, or PROFINET and PROFIBUS interface, for connection of distributed I/O and for communication between programming device, operating device, other SIMATIC controllers or third-party devices.
    Various CPU versions are available for SIMATIC S7-1500:

    • Standard CPUs (as ODK version: capable of executing C/C++ code on the controller)
    • Compact CPUs with digital and analog inputs and outputs as well as counter inputs and high-speed outputs for integrated technological functions direct on the CPU
    • Fail-safe CPUs (as ODK version: capable of executing C/C++ code on the controller) for the execution of standard and safety-related programs on the same computer
    • Technology CPUs with extended motion control functions such as absolute synchronous operation (synchronizing with specification of the synchronized position) and camming.
  • Signal modules for digital and analog inputs/outputs.
  • Technology modules, e.g. for high-speed counting, position detection, or measurement functions.
  • Communication modules and communications processors for expansion of controllers by communications interfaces

The following can also be used depending on requirements:

  • Power supply modules (PS), to supply the internal electronics of the S7-1500 modules via the backplane bus, in case the output of the CPU to the backplane bus is not sufficient for all connected modules. In addition, the 60W 24/48/60 V DC HF PS enables the CPU to retentively store its entire work memory for data.
  • Load power supply modules (PMs) for connecting the SIMATIC S7-1500 to a supply voltage of 120/230 V AC.
  • Interface modules to connect distributed I/O based on S7-1500.
Design

The simple design makes the SIMATIC S7-1500 flexible and service-friendly.

  • Integrated backplane bus:
    The backplane bus is integrated into the modules. The modules are connected via U connectors plugged into the rear of the enclosures. This saves time during installation.
  • Module assembly on S7-1500 mounting rails:
    available in various lengths, including a version for cutting to length. A wide range of standard components such as additional terminals, miniature circuit breakers, or small relays can be snapped on due to the integrated DIN rail.
  • Reliable and user-friendly wiring:
    • The I/O signals are connected via a uniform 40-pole front connector. The mechanical coding between the signal module and front connector prevents destruction of the electronics by accidental incorrect insertion.
    • For simple wiring of the front connector, it can be placed in the “prewiring position”. In this position, the plug has no contact with the module electronics yet. This position can also be used to make changes during operation. The user is supported by a printed cabling diagram on the inside of the front flap.
    • Front connectors are available as versions with screw-type terminals or push-in terminals. Both versions permit the connection of wires with a core cross-section from 0.25 mm2 to 1.5 mm2 (AWG 24 to AWG 16).
    • In addition, system wiring via TOP Connect is available for digital signal modules. It allows the quick and clearly arranged connection to sensors and actuators from the field as well as simple wiring within the control cabinet.
    • For analog modules, the shielding can take place direct on the module; a shield connection set that can be installed without tools is included with the module.
  • Plant-specific labeling:
    Labeling strips are available for the signal modules of the SIMATIC S7-1500. These DIN A4 sheets can be labeled using a standard laser printer. Automatic printing is possible from the TIA Portal without having to re-enter the symbols or addresses. The labeling strips are designed such that there is a 1:1 assignment of the labeling for channel or diagnostics display. If the front flap is opened, this 1:1 assignment of diagnostics display to terminal is retained.
  • Variable and scalable station setup:
    • Signal modules and communication modules can be inserted in any way without restrictions. The system configures itself.
    • The maximum configuration comprises the CPU with 31 modules (30 modules + 1 power supply). The power supply (PS) is required to supply the internal electronics of the S7-1500 modules via the backplane bus, in case the output of the CPU to the backplane bus is not sufficient for all connected modules.
  • Compact dimensions:
    The dimensions of the SIMATIC S7-1500 are such that it fits in the available installation space of a SIMATIC S7-300 or ET 200M without problems.
  • Flexible installation:
    The SIMATIC S7-1500 and its modules can be installed both vertically and horizontally and thus provide an optimum fit to the available space.
I/O modules

The following module types are available for use on a SIMATIC S7-1500/ET 200MP:

  • Standard and fail-safe digital input modules
  • Standard and fail-safe digital output modules
  • Digital input/output modules
  • Analog input modules
  • Analog input/output modules
  • Analog output modules
    • Including high-speed (HS) analog modules with a basic execution time of 62.5 µs, regardless of the number of activated channels
  • Technology modules for counting and positioning
  • Communication modules for point-to-point communication and bus connection

Various module classes are available to provide users with optimum scalability in their application. The modules themselves are labeled accordingly:

  • BA (Basic): Simple, cost-effective modules, without diagnostics and without parameters
  • ST (Standard): Modules with module-specific or load group-specific diagnostics and, if applicable, with parameters; for analog modules: accuracy class 0.3%
  • HF (High Feature): Modules with channel-specific diagnostics and parameter setting; for analog modules: accuracy class 0.1%, increased immunity and galvanic isolation
  • HS (High Speed): Modules with extremely short filter and conversion times for very fast applications; e.g. 8-channel analog modules with a basic execution time of 62.5 µs, regardless of the number of activated channels.

Accessories for I/O modules:

  • Labeling sheets:
    For insertion in the I/O modules (10 DIN A4 sheets with 10 strips each, preperforated, for printing with a standard laser printer; available color: Al grey)
  • Shield connection:
    A simple shield connection set that can be installed without tools is available for the SIMATIC S7-1500 system (analog modules and technology modules). This consists of a 24 V DC infeed element, a shield clamp, and a universal shield terminal. The latter is designed so that it can be used for a single thin trunk cable, several thin trunk cables, or a thick trunk cable. Consistent separation of 24 V DC infeed and measurement signals as well as a low-impedance connection between shield and signal cables ensure high EMC stability and high resistance to interference.
  • Uniform 40-pole front connector
  • Additional accessories such as the front doors for the I/O modules or the U connectors for the self-assembling backplane bus
Communication

The S7-1500 features different communication interfaces:

  • PROFINET IO IRT interface (2-port switch), integrated in the CPU;
    for defined response times and high-precision plant behavior.
  • Communications processors for connecting to the PROFIBUS, Industrial Ethernet and PROFINET bus systems
  • Communication modules for point-to-point connections.

From CPU 1515, all CPUs feature one or more additional integrated PROFINET interfaces with separate IP address, e.g. for network separation or for connecting additional PROFINET IO devices. From CPU 1516-3 PN/DP, PROFIBUS nodes can be connected via the integrated PROFIBUS interface. The CPUs without integrated PROFIBUS interface can be easily expanded via a PROFIBUS CM.
