As with other programmable logic controllers, SIMATIC devices are intended to separate the control of a machine from the machine's direct operation, in a more lightweight and versatile manner than controls hard-wired for a specific machine. Early SIMATIC devices were transistor-based, intended to replace relays attached and customized to a specific machine. Microprocessors were introduced in 1973, allowing programs similar to those on general-purpose digital computers to be stored and used for machine control. [1] SIMATIC devices have input and output modules to connect with controlled machines. The programs on the SIMATIC devices respond in real time to inputs from sensors on the controlled machines, and send output signals to actuators on the machines that direct their subsequent operation.

Depending on the device and its connection modules, signals may be a simple binary value ("high" or "low") or more complex. More complex inputs, outputs, and calculations were also supported as the SIMATIC line developed. For example, the SIMATIC 505 could handle floating point quantities and trigonometric functions. [2]

History

Siemens Simatic N

On April 2, 1958 the name Simatic (composed of "Siemens" and "Automatic") was registered with the German Patent and Trademark Office (DIN) as a registered trademark of the company Siemens.

A year later, in 1959, the Simatic G [3] was launched on the market, a system that could replace relay logic with a hard-wired programmed logic controller (based on the use of Germanium transistors). The system was launched under the name "Building-Block System for Solid-State Controls".

In 1964, the Simatic N (1964) was launched (hard-wired programmed logic controller) - based on Silicon transistors.

In 1973, the Simatic S3 was launched, the first microprocessor-based Simatic system that implemented programmable logic. [4]

In 1979, the Simatic S5 series was launched, a series that was maintained until 2000. Automation systems based on Simatic S5 are still functional worldwide. S5 systems were programmed using the STEP 5 software system. In 1984 the Simatic S5 U (universal) programmable controller series is introduced.

In 1994, the Simatic S7 series was launched, a series based mainly on the S7-200 controllers (dedicated to simple automation systems), S7-300 (suitable for almost any automation system) and S7-400 (dedicated to large and very large automation projects). All controllers in these series allow networking, especially in Profibus or Industrial Ethernet networks.

In 1996 Siemens presented the concept of "Totally Integrated Automation", initially a concept referring to the interconnectivity of automation equipment. [5]

In 2009, the S7-1200 series of PLCs was launched, a series that replaced the S7-200 series.

In 2011, the TIA Portal (Totally Integrated Automation Portal) software package was also launched, a software platform dedicated to the complex programming of automation systems.

In 2013, the S7-1500 series appeared on the market, a new generation of programmable logic controllers intended to replace the S7-300 and S7-400 series over time.

S7-1200 G2, a second generation of the S7-1200, was launched in December 2024.

Controllers

SIMATIC control systems (PLC) are designed to automate as much of the control of industrial plants as possible. Through the system inputs and outputs, it can monitor and control process elements (operation flow, mechanical element status, temperature, pressure) reducing the need for continuous supervision by a human operator.

The operating logic is stored in the form of a software program in the memory of a Central Processing Unit type control system. The automation system is modular and, in addition to the CPU, can be equipped with various digital and/or analog peripheral modules, as well as intelligent control modules. The modules can be configured centrally (mounted in close proximity to the CPU unit) or decentralized, close to the controlled plant. The range of controllers extends from small, compact controllers to high-performance PLC systems. What all Simatic controllers have in common is their robustness against electromagnetic interference (e.g. Simatic-S7 complies with the requirements of Directive 2014/30/EU on electromagnetic compatibility and climatic stress - e.g. 0 to + 60 °C ambient temperature during operation). Simatic is programmed using STEP 7 (formerly STEP 5) programming software or software from third-party manufacturers.

Siemens has developed more product lines to date. First versions were hard-wired, the first processor based series being SIMATIC S3

SIMATIC S3

(starting from 1973)

S3 was based on hard-wired logic SIMATIC C3.

Simatic S5

(1979 - 2000)

The S5 line was sold in various chassis configurations. Within each chassis style, several CPUs were available, with varying speed, memory, and capabilities. Some systems provided "fail-safe" control, used for safety applications or redundant CPU operation for ultra-high-reliability control, as used in pharmaceutical manufacturing, for example.

Each configuration was built starting from the central unit to which the various input and output modules, communication or modules for special functions were attached. The compact variants were configured by directly coupling the modules onto the support rail, the complex variants were configured by mounting modular boards in a dedicated drawer.

Simatic S7 (S7-200, S7-300, S7-400)

(since 1994)

The first entries in the S7 line were released in 1994, available under three performance classes: S7-200, S7-300 and S7-400. The introduction of SIMATIC S7 saw also the release of a new fieldbus standard Profibus, and the pioneer use of industrial Ethernet to facilitate communication between automation devices. The great success of the S7-300 CPU family in particular helped to cement the role of Siemens as one of the global leaders in automation technology. These series are expected to be phased out in 2033. [13]

Software

The first generations of Simatic control systems (Simatic G, Simatic S) were implemented using hard-wired programmed logic controllers. Simatic S3 was the first microprocessor-based control system that allowed programmable logic.

Simatic S5, launched in 1979, was initially programmed using special programming consoles and later using the STEP 5 software package, one of the first advanced PLC programming software. [21]

For programming the Simatic S7 300 and 400 systems, Siemens has launched the software package STEP 7, the Simatic S7 200 series being programmed with a separate software called STEP 7 MicroWin.

With the introduction of the S7 1200 and S7 1500 series controllers on the market, Siemens has launched a new software package called TIA Portal (Totally Integrated Automation Portal). It allows programming of the new generation S7 1200 and S7 1500 controllers as well as controllers from previous series. [22]

STEP 5

Sample PLC program STEP5 LAD

STEP 5 (name derived from STeuerungen Einfach Programmieren = easy programming of control systems) is a programming and diagnostic software for the Simatic S5 series of programmable controllers, originally released in 1979 only on the PG630 programming consoles, under the operating system CP/M. With the withdrawal of Simatic S5 systems from production, STEP 5 continued to be offered by Siemens but development of the software package was discontinued. The latest edition is version 7.2 (with upgrade to version 7.23 Hotfix 1 with patches) and can run (under certain conditions) on Windows 10 systems and is offered by Siemens for certain configurations of Field PG M6 programming consoles.

STEP 5 was offered in two versions:

Step 5 Standard, which can be used for programming, testing, commissioning and automatic generation of documentation for the Simatic S5-90U, S5-95/U/F, S5-100U, S5-101U, S5-115U/H/F, S5-135U, S5-150U and S5-155U/H series controllers.

Step 5 for mini PLCs, limited to the S5-90U, S5-95U/F and S5-100U controllers and allowing only a limited number of optional software packages: GRAPH Mini, COM IP 266, COM 95F, COM DG1, COM 521 BASIC.

Software modules

Since the first computers (Field PG programming consoles) had limited hardware resources (e.g. restrictions on RAM capacity), STEP 5 was developed modularly, in individual software packages that were launched (and loaded into memory) only when they were needed. [23] [SIOS ID: [24] 19417353]

LAD, CSF, STL

This module contains the editors for user programs. Programming of Simatic S5 PLCs can be done in one of the following languages:

XRF, COMP, REW

EPROM / EEPROM

It allows the transfer of the PLC program from PG (or PC) to EPROM (or EEPROM), from EPROM / EEPROM to PG / PC or the comparison of the program from PG / PC with that in EPROM / EEPROM. (PG = Programming Console, PC = Personal Computer).

Symbol Editor

An editor through which each operand can be assigned a symbol and a comment that can be viewed in program editors.

Optional COM modules

Various optional packages, such as GRAPH5 (for sequential programming), PG-NET (networking), KOMDOC (generate documentation), COM266 (for IP266 positioning module), COM723 (for WF723 CNC module), COM-ET200 (for distributed periphery), etc.

OB, PB, SB, FB/FX, DB/DX blocks

In STEP 5 the program can be structured into blocks whose execution can be controlled.

STEP 7 integrated in TIA Portal

(starting with v10)

In April 2009, Siemens initiated a generational change in the Simatic S7 controllers by launching, first, the S7-1200 controller family. For their programming, a new version of the programming software was also released, initially called STEP7 Basic V10.5. Later, with the launch of version 11, the new software version was integrated into a complex development environment called TIA Portal (Totally Integrated Automation Portal), which includes, in addition to STEP 7, the WinCC packages (for programming operator panels), StartDrive (for parameterizing variable speed drives) as well as optional modules, depending on the version.

In the versions integrated in the TIA Portal, STEP 7 offers various options for configuring and debugging PLCs:

Hardware Editor: For configuring the automation system and parameterizing the modules that are settable.

Symbol Editor: For defining the global tags used, the symbolic names, data types and comments for them.

S7-PLCSIM: A simulator of Simatic S7 systems that allows testing an automation project in a virtual environment.

Program editor: For editing user programs using one of the standardized PLC programming languages (according to EN 61131-3):

Under TIA Portal (especially for S7 1200 and S7 1500 PLCs) the LAD and FDB languages offer a complete set of instructions and the program is transferred to the PLC directly in the language it was written in. Program blocks can be converted from LAD to FDB or vice versa but can no longer be converted directly into other languages (in STEP 7 versions v1.x to v5.x for S7 300 and S7 400 the program was interpreted in STL and LAD and FBD were program display modes).
