Connection to PROFIBUS or PROFINET

Via interface modules the ET 200 pro is connected to the bus system, either the proven fieldbus PROFIBUS or PROFINET the leading Industrial Ethernet Standard.SIMATIC ET 200pro offers
flexible connection techniques, realized by separating interface and connection modules .

Benefits

  • Flexible connection techniques

  • Integrated safety functionality

  • Comprehensive diagnostic functions


Design and function

Interface modules for PROFIBUS

The Interface modules (IMs) for PROFIBUS can be combined with three different modules for connecting the bus and power supply. All connection modules for PROFIBUS have visible address setters that allow the addresses to be easily read, as well as a selectable terminating resistor. The integrated T functionality supports the start-up of partial segments and uninterrupted bus communication in the event of a servicing requirement.

SIMATIC ET200pro PROFIBUS Interface modules

  • Direct connection with cable gland:
    For up to 16 A electronic load and a cross-section of up to 2.5 mm².

  • ECOFAST (Energy and Communication Field Installation System)
    The standardized Siemens connection technique for cabinet-free distribution is based on hybrid cables for bus signals and power supply.

  • M12, 7/8'': The familiar connection method with widely implemented connector standard.


Interface modules for PROFINET
The Interface module (IM) for PROFINET features a 2-port switch for easy configuration of a line structure. More parameters are possible per station using PROFINET, and therefore more high-function modules can be used. In case of service, the IM can be replaced without using a programming device –the device name and parameters remain on the module. As with the PROFIBUS variant, the interface module and the connection module on the Interface module IM 154-4 PN HF are separated so that various connection methods are possible.
The Interface module offers both the proven M12 7/8" connection and the option of the connection with push-pull technology.
