The simple design of SIMATIC S7-1500 serves its versatility and user-friendliness well.

Integrated Backplane: The backplane is integrated into the modules. The modules are connected to each other through U connectors located behind the cages. This saves installation time. Module mounting on the DIN rail S7-1500: Available in various sizes, including a version that can be cut to length. Due to the integrated DIN rail, standard items such as additional terminals, short-circuiting devices, or small relays can be easily connected to the rail. Reliable and user-friendly wiring: Input/output signals are connected through a front 40-pin integrated connector. Mechanical coding between the signal module and the front connector prevents accidental incorrect insertion. For easy wiring, the front connector can be placed in the “pre-wiring” state. In this state, the plug does not yet make contact with the module electronics. This state can also be used for making changes during operation. The user is supported by a printed wiring diagram inside the front cover cap. Front connectors are available in versions with screw terminals or push-in terminals. Both options allow the connection of wires with a core cross-section from 0.25 square millimeters to 1.5 square millimeters (AWG 24 to AWG 16). In addition, wiring for the system is also available via TOP Connect for digital signal modules. This allows the user to quickly and smoothly connect sensors and actuators from the field and simplify wiring inside the control cabinet. For analog modules, connections can be made directly on the module; a shielded connection set that installs without tools is included with the module. Specially designed factory labeling: Label strips for SIMATIC S7-1500 signal modules are available. These DIN A4 sheets can be labeled using a standard laser printer. Automatic printing from TIA Portal is possible without re-entering symbols or addresses. The label strips are designed to maintain a one-to-one relationship between channel or display labeling and the connector when the front cover cap is open. Flexible and scalable station setup: Signal modules and communication modules can be inserted in any way without any limitations. The system configures itself. The maximum configuration includes a central processor with 31 modules (30 modules + 1 power supply). Power supply (PS) is necessary through the backplane bus to supply the internal electronics of the S7-1500 modules if the processor output to the backplane is not sufficient for all connected modules. Small dimensions: SIMATIC S7-1500 is designed to fit properly in the installation space of a SIMATIC S7-300 controller or ET 200M I/O system. Flexible installation: SIMATIC S7-1500 and its modules can be installed both horizontally and vertically for optimal placement in the available space.

BA (Basic): Simple and cost-effective modules, without detection and parameters.
ST (Standard): Modules with module or specific group detection and, if necessary, with parameters; for analog modules: accuracy class 0.3%.
HF (High Feature): Modules with specific channel detection and parameter setting, supporting isochronous mode, and for analog modules: accuracy class 0.1%, increased electromagnetic compatibility, and galvanic isolation.
HS (High Speed): Modules with very short filter times and conversion times for very fast applications, supporting isochronous mode; for example, 8-channel analog modules with an initial execution time of 62.5 microseconds, regardless of the number of activated channels.
Accessories for I/O modules:

Labeling: For placement in SIMATIC S7-1500 I/O modules (10 DIN A4 sheets with 10 strips each, pre-cut, for printing with a standard laser printer; available in various colors: aluminum gray).
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 includes a 24V DC power supply, a protective bracket, and a universal protective terminal. It is designed to be used for a single fine-wire cable, multiple fine-wire cables, or a fine-wire cable. Separating 24V DC and measurement signals in one, and also connecting with low-impedance between protection wires and safety signal wires with high EMC interference resistance and high resistance to interference ensures compliance with interference specifications. Integrated 40-pin Front Connector:

Additional Accessories: Such as front doors for I/O modules or self-tapping U connectors for the backplane.

General Design of S7-300:

The S7-300 automation system is designed modularly, featuring a comprehensive range of modules that can be used individually or in combination with each other.

A system comprises the following:

Central Processing Unit (CPU): Various types of CPUs are available for different performance classes, including CPUs with integrated inputs/outputs and corresponding functions, as well as CPUs with PROFIBUS DP, PROFINET interfaces, and point-to-point connections.
Signal Modules (SM) for digital and analog input/outputs.
Communication Processors (CP) for network connections and point-to-point connections.
Functional Modules (FM) for high-speed counting, positioning (loop/open loop), and PID control.
Depending on requirements, the following can also be used:

Power Supply (PS) for connecting S7-300 to 120/230 V AC supply voltage.
Interface Modules (IM) for connection to the Central Controller (CC) and expansion units (EU) in multilevel combinations.
S7-300 can operate with up to 32 modules distributed in CC and 3 EUs. All modules can function in fanless enclosures.

Additionally, SIPLUS modules can be utilized for extended environmental conditions:

Suitable for temperatures ranging from -25 to +60 degrees Celsius, humidity, condensation, and frost.
Direct use in vehicles or outdoors in an IP20 protected cabinet against direct sunlight and rain/splash water.
No need for artificial ventilation and IP65 residential locations.
The simple design provides flexibility and ease of maintenance for S7-300:

Module Installation: Simply mount the modules on the rail, align them to the appropriate position, and secure them in place.

Backplane Connection: The backplane is integrated into the modules. Modules connect to each other via backplane connectors located on the back of the frames.

Easy Replacement of Modules with Mechanical Coding: To replace a module, just loosen the module fixation screw. Front connections with connected wires are easily detachable by pressing the front lock mechanism. Front connector coding prevents connecting the front wire connector to the wrong module.

Tested Field Connections: For signal modules, front connections are provided in screw, push-in, or insulation displacement types.

TOP Connect: It offers pre-assembled connections with one to three cores and screw or push-in connections. It is an alternative to direct connection to signal modules.

Defined Installation Depth: All connections and connectors inside the modules are hidden and protected under front doors. This ensures that all modules have a defined installation depth.

No Slot Rules: Signal modules and communication processors can be connected to each other without any restrictions. The system configures itself.

Expansion

If a user requires more than 8 slots for SM, FM, or CP modules for their automation tasks, the S7-300 (excluding CPU 312 and CPU 312C) allows expansion:

Maximum of 32 modules on CC and 3 EUs: All, up to 3 expansion units (EUs), can be connected to the central controller (CC). Eight modules can be connected to each CC/EU.

Connection via interface modules: Each CC/EU has its own interface module, always located in the slot next to the CPU on the CC, and communicates independently with the EUs.

Expansion via IM 365: 1 EU, maximum distance of 1 meter, and power supply is also transferred.

Expansion via IM 360/361: 3 EUs, maximum distance between CC and EU, and between EU and EU, is 10 meters each.

Physically separated installation: CCs/EUs can still be installed even when at large distances from each other. Distance between two CCs/EUs or EU/EU: Maximum 10 meters.

Communications

SIMATIC S7-300 processors support the following types of communications:

Process communication: For cyclic addressing of input/output modules (process image exchange) via a bus (AS-Interface, PROFIBUS DP, or PROFINET). Process communication is called from cyclic executive levels.

Data communication: For data exchange between automation systems or between HMI stations and various automation systems. Data communication is performed cyclically or invoked based on events through user-programmable blocks. The user-friendly STEP 7 interface, which significantly simplifies configuration, is available to users for configuring communication functions.

Data Communication

SIMATIC S7-300 supports various data communication mechanisms:

Cyclic exchange of data packets between processors formed by MPI with global data communication. Event-driven communication with other partners using communication functions. Networking can be done through MPI, PROFIBUS, or PROFINET.

Global Data

With the “Global Data Communication” service, network processors can cyclically exchange data with each other (up to 8 GD packets with a size of 22 bytes each per cycle). This allows, for example, one processor to have access to the data, bit memories, and process images of another processor. Global data communication is only possible via MPI and is configured using the GD table in STEP 7.

Communicative Functions

Communicative services with S7/C7 partners can be created with system-compliant blocks.

These services include:

Primary S7 communication via MPI.

S7-300 can be used as a server via MPI, C bus, and PROFIBUS.
S7-300 can be used as a server or client via the integrated PROFINET interface.
Communicative services with S5 and non-Siemens devices can also be created with reusable blocks.

These services include:

Compatible communication with S5 via PROFIBUS and Industrial Ethernet.
Standard communication (non-Siemens systems) via PROFIBUS and Industrial Ethernet.
Unlike global data, communication functions require configuring communication connections.

Integration into the IT World

Using SIMATIC S7-300, it’s possible to seamlessly connect the modern IT world with automation engineering. The following IT functions can be performed through CP 343-1 Advanced:

IP Routing:

Sending IP V4 messages from the gigabit interface to the PROFINET interface controlled by the IP access list.
Web Server:

Up to 30 megabytes of custom HTML web pages can be called by a standard web browser; data processing can be done through its file system using FTP.
Standard Diagnostic Pages:

For high-speed diagnostics in all installed modules without additional tools.
Email:

Sending emails with direct authentication from the user program. Email client functionality allows direct user alerting from the control program.
Communication via FTP:

An open protocol available on most operating system platforms.
The 30-megabyte RAM file system can be used for temporary storage of dynamic data. S7-300 PROFINET processors have an integrated web server. Therefore, various information can be read from the S7-300 station using a standard web browser:

General CPU information
Diagnostic buffer content
Variable table
Tag status
Module status
Alarms
Information about Industrial Ethernet
The topology of PROFINET nodes with user-defined pages can also be accessed for writing through the web server to the S7-300 processor.
Isochronous Mode

The isochronous mode system function enables synchronous connections for:

Collecting synchronous distributed signals,
Transferring signals via PROFIBUS/PROFINET, and
Executing the program in a constant time cycle PROFIBUS/PROFINET provides.
An automation solution is created that collects input signals at fixed time intervals (constant bus cycle time) and processes them. At the same time, a unified process image is created.

S7-300 precisely defines and reproduces process response times with functions for constant bus cycle times and simultaneous processing of distributed signals.

A broad range of components supporting the isochronous mode system function is available to perform demanding tasks in control motion, measurement value collection, high-speed control, etc.

In distributed automation solutions, SIMATIC S7-300 can open up as a crucial application area in high-speed processing operations to provide maximum precision and repeatability. This translates into increased production with optimal and consistent quality.

Monitoring and Control of Module Processes

Many SIMATIC S7-300 input/output modules have intelligent capabilities:

Monitoring signal collection (diagnostics)
Monitoring process signals (hardware inputs)

Detection

Detection can be used to determine whether signal collection (in the case of digital modules) or analog processing (analog modules) is being carried out by the module without errors or not. In diagnostic analysis, a distinction must be made between parameterizable and non-parameterizable diagnostic messages:

Parameterizable diagnostic messages:

Diagnostic messages are only sent if activated by the appropriate parameter.
Non-parameterizable diagnostic messages:

These messages are sent naturally, meaning independently of parameterization.
If an active diagnostic message exists (such as “Sensor power failure”), the module creates a diagnostic interrupt (only after appropriate parameterization if the diagnostic message is parameterized). The central processing unit pauses the user program processing or lower priority classes and processes the corresponding diagnostic interrupt block (OB 82).

Hardware Interrupt

Signal processes can be monitored through hardware interrupts, and responses to changes in signals can be invoked.

Digital Input Modules: Depending on parameterization, the module can optionally call a hardware interrupt on a rising edge, a falling edge, or on both edges for each channel group. The CPU pauses user program processing or lower priority classes and processes the corresponding diagnostic interrupt block (OB 40). The signal module can buffer one interrupt for each channel.

Analog Input Modules: By parameterizing a maximum and minimum value, a working range is defined. The module compares the digitized measured value with these limits. If the measured value violates any of these limits, a hardware interrupt is invoked. The CPU pauses user program processing or lower priority classes and processes the corresponding diagnostic interrupt block (OB 40). If the value is above/below the upper/lower limit, no comparison is made.

S7-300F

The S7-300F safety functions operate in the F CPU program and safety signal modules.

Safety signal modules monitor signals through signal analysis, difference analysis, and input signal tests.

The CPU performs regular self-tests, instruction tests, and logical and timing checks to ensure proper controller functioning. Additionally, I/O is checked with “alive” requests.

If an error is detected in the system, the system enters a safe state.

Safety-related programming for CPU 315F is written in STEP 7 LAD and FBD languages. The operating range and data types are limited here. A safety program is created with special specifications during the compile stage. Additionally, a standard program can run concurrently with a safety program on a CPU without any limitations (interference).

An additional part of this software package is the F library with programming examples ready and certified by TÜV for safety functions. These programming examples are modifiable, but changes must be re-certified.

The text describes a safety feature package called “S7 F Distributed Safety” for programming safety-related parts of a program. It includes functions and blocks necessary for creating an F program, requiring STEP 7 version 5.1SP3 or later for S7 F Distributed Safety execution. The technical specifications cover protection degree, environmental conditions, humidity, air pressure, insulation, electromagnetic compatibility, mechanical resistance, vibration, shock, and more.
