ET 200S Safety motor starter Solution PROFIsafe

Interplay of ET 200S Safety Motor Starter Solution PROFIsafe components

Components for ET 200S Safety motor starter Solution PROFIsafe

ET 200S Safety Motor Starter Solutions PROFIsafe consist of (see example):

• PMD F PROFIsafe safety modules
• Failsafe motor starters
• Safe control system is used with the bus systems PROFINET or PROFIBUS with the PROFIsafe profile

Functionality of the ET 200S Safety motor starter Solution PROFIsafe

• For using Failsafe motor starters in plants with PL c to PL e according to ISO 13849-1 and SIL 2 and 3 according to IEC 62061. Use with Standard or High Feature motor starters is also possible with certain combinations.
• High flexibility (any assignment of sensors to motor starters using the PLC)
• Full selectivity of disconnection of the Failsafe motor starters
• No complex wiring for conventional safety systems, e. g. no infeed contactors even in the highest safety category
• Can also be used to activate external safety systems through F-CM contact multiplier
• Safety module available for any safety function
• Safety module available for Stop category “0” and “1”
• Safety module for monitoring the auxiliary voltages for motor starters
• Safety modules can be plugged into the TM-PF30 terminal modules

Sensor and actuator assignment are freely configurable within the framework of the distributed safety concept:

The logic of the safety functions is implemented by software. Safety-oriented PROFIsafe communication and the use of a safety-oriented control system are required. Integration of the safety technology in the standard automation is realized through a single bus system (see Advantages of PROFIsafe), using PROFIBUS as well as PROFINET.

High degree of flexibility with safety technology
Failsafe motor starters for PROFIsafe:

In EMERGENCY-STOP applications, the Failsafe motor starters are selectively switched off through the upstream PM-D F PROFIsafe safety module. For each safety module, six switch-off groups can be formed. In the first delivery stage, the failsafe freely-programmable logic of the SIMATIC controller is used to interface with the relevant Failsafe sensor technology.

F-CM contact multipliers

The interface between PROFIsafe and installations that use conventional safety technologies is implemented through the F-CM Failsafe contact multiplier with four floating contacts.

PM-D F PROFIsafe safety modules

The PM-D F PROFIsafe safety module receives the shutdown signal from the interface module of the ET 200S and safely switches off one to six switch-off groups. This safety module is used in PROFIsafe applications where there is a need for the selective safety shutdown of Failsafe motor starters/frequency converters.

Terminal modules

The terminal assignment of the terminal modules for safe motor starters corresponds to the terminal assignment of the 45 mm and 65 mm terminal modules. The terminal modules for safe motor starters have a coding module in addition. This enables the safe motor starter to be assigned to one of the six switch-off groups.

The terminal module contains three coding elements which fully cover the three coding openings in the terminal module. The labeled coding element contains (in the chamber marked with the dash) the busbar tap; the non-labeled coding elements are used only to cover the coding openings. Switch-off group 1 (AG1 or SG1) is coded in the as-delivered state. The coding can be changed to switch-off group 2 by releasing the coding element and turning it through 180В°. Changing the coding to switch-off group 3 is possible by exchanging the labeled and blank coding elements. In this case the dash on the labeled coding element must correlate with the dash of the required switch-off group (symbolized busbar).

The Failsafe motor starters are assigned to one of the six possible switch-off groups.

The diverse possible uses of the Safety motor starter Solution PROFIsafe are presented in the manual SIMATIC ET 200S Motor Starters in the context of typical sample applications.

Safety functional examples for easy, quick and low-cost implementations of applications with Safety Motor Starter Solution PROFIsafe are also available on the Internet.

ETВ 200S Safety Motor Starter Solutions PROFIsafe with Failsafe motor starters and fully selective disconnection (PM-DF PROFIsafe application)

The Failsafe motor starters are assigned to one of six safety segments within an ET 200S station. For plants with distributed configuration the shutdown signals of these safety segments are preferably issued by a higher-level, safety-oriented control system through PROFIsafe. This permits the greatest flexibility for assigning the motor starters to different safety circuits.

Alternatively, an ET 200S F-CPU can also be used for control purposes.

If a safety-oriented SIMATIC CPU is used, the ET 200S is available as a safety-oriented peripheral. Nevertheless, in such a station it is possible to configure conventional motor starters and input/output modules mixed with modules with safety functions.

Thanks to the PROFIsafe profile, the safety functions are available in the complete network, which means that the Safety motor starter Solutions PROFIsafe enable the selective disconnection of a Failsafe motor starters or the disconnection of a group of Standard and High Feature motor starters regardless of where and on which peripheral station the safe control devices were connected. As such, this solution provides an unprecedented level of flexibility and reduction of wiring for applications in wide-spread plants or with a sporadic demand for changes in the assignment of safety segments.

The Saftey motor starter Solution PROFIsafe is ideally suited for safety concepts with Cat. 2 to 4 according to EN 13849-1- or up to SIL 3 according to IEC 62061.

Each safety module switches up to six switch-off groups for Failsafe motor starters/frequency converters.
