For use within explosive plants

Description

In many branches there exist explosive environments in manufacturing and following processes.

To assure a preferably high level of safety in these areas, there exist conditions in terms of laws, orders and norms.

For the use in these areas, there are Ex modules that are endorsed intrinsically-safe sensors and actuators being in zone 1 or 2 of explosive plants.

Area of application

The Ex modules are available to the automation particularly of chemical plants as appropriate operating supplies. They are applicable for applications in the measurement-, control- and regulation technology.

Areas of application:

  • Chemical/petrochemical industry

  • Gas industry 

  • Offshore industry

  • Transportation (e.g. tankers) 

  • Automotive engineering (e.g. at varnishing) 

  • Energy supply, energy distribution etc.

  • Generating plants

  • Special engineering (e.g. printing machines, cleaning machines)


Benefit

The igniting protection type intrinsically-safe offers following advantages to the user:

  • Easy interchangeability of intrinsically-safe  equipment during the business

  • Easy measurement and calibration of the measuring section during the business

  • Working in intrinsically-safe  energized loops without stop of the plant

  • No complex case execution (e.g. compression-proof encapsulation) necessary

  • Linking of intrinsically-safe equipment of different manufacturers possible

  • Approved igniting protection type in chemical industry


Design and functions

The main function of the analog Ex modules is the separation of the intrinsically-safe loops of the Ex field and the non intrinsically-safe internal loops of the automation plant.
The Ex analogl input modules transform the analog signals of the intrinsically-safe equipment in digital values for the following working.

The Ex analog output modules transform the digital signals of the automation plant in analog signals being necessary for the process.
Ex analog input/output modules are “appropriate electrical eqipment” of the igniting protection type intrinsically-safe (term [EEx ib] IIC according to DIN EN 50020). You get next to intrinsically-safe ones also non intrinsically-safe loops.

  • Same systems engineering as the other modules of S7-300

  • Galvanic separation of the module

  • Confusion safety through coding

  • Supply of the sensors and actuators through the module

  • Direct wiring of the inputs and outputs of the modules without a separating switch amplifier or transmitter feed unit

  • Different wiring of the software possible

  • Diagnosis capable modules

  • Reduced  planning, installation and documentation effort 

  • Operation also with ET 200M possible with connection to all SIMATIC automation systems and as norm slave to all PROFIBUS DP networks.

S7-300 Signal modules

Description

Digital actuators and sensors can be connected to a SIMATIC S7-300 via digital modules. The extensive range of modules allows the most suitable signal module to be selected in each case.

Area of application

Digital input/output modules contain digital inputs/outputs for the automation system. Digital sensors and actuators can be connected to the automation system via these modules. Switches and 2-wire proximity switches (BEROs) can be connected to input modules, for example. Output modules are suitable for connection of solenoid valves, contactors, small motors, lamps and motor starters.

Benefits

The use of digital input/output modules provides the user with the following advantages:

  • Optimum adaptation;
    since almost any combination of modules is possible, the number of inputs/outputs can be matched to suit the task in hand. Superfluous investments no longer exist

  • Flexible process connection;
    the wide variety of digital actuators and sensors facilitates connection of the automation system to the process

Design and functions

Digital input/output modules exhibit the following mechanical characteristics:


Compact design 
The rugged plastic housing features:
• Green LEDs for displaying the signal states at the inputs/outputs
• Slot for the front connector, protected by the front cover
• Labeling area on the front cover


Easy assembly
The modules are mounted on DIN rails and connected to adjacent modules via bus connectors. There are no slot rules, the input addresses are determined by the slots.

When used in the ET 200M distributed I/O station together with active bus modules, the modules can be hot-swopped during operation without affecting the other modules.

User-friendly wiring

The modules are wired by means of a front connector. When they are first plugged in, a coding element clicks into place so that the connector will only fit into modules of the same type. When the module is replaced, the front connector can be used in its fully-wired state for a new module of the same type.

Module overview

Description

The multi-facetted module range of S7-300 allows modular customization to suit the most varied tasks.
Function modules are intelligent modules that independently execute the technological tasks like counting, measuring, cam control, PID control and motion control. Thus they reduce the load on the CPU.
They are used when a high level of accuracy and dynamic response is required.

Applications

  • Wood, glass, stone and metal processing

  • Packaging machines 

  • Presses

  • General machine manufacturing

  • Machine tools

  • Textile machines

  • Rubber and plastic industry

  • Plants


Benefit

  • High degree of accuracy and dynamic response

  • Specialized and universal modules with a wide range of functions

  • CPU is not involved since the functionality is stored in the firmware of each module

  • Quick reaction times (deterministic dynamic response)

  • Engineering with configuring tool, integrated into STEP 7


Design and function

Function modules are intelligent modules that independently execute the technological tasks and thus reduce the load on the CPU.
Configuration tools based on STEP 7 and STEP 7-Micro/WIN are available for setting parameters. Parameterization and commissioning are performed via user-friendly screens.
The function modules of the S7-300 can also be used in a distributed configuration in the
ET 200M I/O system – also with PC-based automation with WinAC.

S7-300 Signal modules

More complex tasks require the processing of analog process signals. Analog actuators and sensors can be connected to a SIMATIC S7-300 via analog modules without additional amplifiers. The extensive range of modules allows the most suitable signal module to be selected in each case.

Area of application

Analog input modules facilitate connection of the controller to the analog signals of a process. They are suitable for connecting analog sensors such as voltage and current sensors, thermocouples, resistors and resistance thermometers as well as analog actuators.

Benefits

The use of analog input/output modules provides the user with the following advantages:

  • Optimum adaptation:
    Since almost any combination of modules is possible, the number of inputs/outputs can be matched to suit the task in hand. Superfluous investments no longer exist

  • High-performance analog technology:
    A variety of input/output ranges and high resolution facilitate connection of a multitude of analog sensors and actuators

Design and functions

The use of analog input/output modules provides the user with the following advantages:

  • Red LED for group faults

  • Slot for the front connector, protected by the front cover

  • Labeling area on the front cover

 

When used in the ET 200M distributed I/O station together with active bus modules, the modules can be hot-swopped during operation without affecting the other modules.

 

User-friendly wiring

The modules are wired by means of a front connector. When they are first plugged in, a coding element clicks into place so that the connector will only fit into modules of the same type. When the module is replaced, the front connector can be used in its fully wired state for a new module of the same type.

Intelligent counter module for counting tasks

 

FM 350-1

The intelligent FM 350-1 counter module has one counting channel for up and down counting, and is an excellent choice for universal high-frequency counting tasks up to 500 kHz.
It also features measuring functions for speed, frequency and period length. In distributed configurations with S7-400 or WinAC RTX, the FM 350-1 supports isochrone mode.

FM 350-2

The FM 350-2 counter module, by contrast, is an 8-channel counter module for universal counting and measuring tasks up to 20 kHz.
It can be used in the SIMATIC S7-300 and in the ET 200M (with S7-300/S7-400 as master).
