PROFINET Fieldbus system

What is PROFINET?

PROFINET is an open Industrial Ethernet standard developed by Siemens and the PROFIBUS User Organization e.V. (PNO). PROFINET uses TCP/IP, is real-time capable, and allows devices from different manufacturers to communicate without any special interface adaptations. The concept behind PROFINET is a modular one, so that the user can decide which functionality to use. PROFINET is used to connect decentralized peripherals to a control system. The standard is used in the manufacturing industry, process industry, and logistics for the efficient control and monitoring of production processes.

Number of ASi networks, number of ASi Master

" yes, max. 4 A/ASi network ":

Data decoupling integrated in the gateway. Cost-effective power for 2 ASi networks with 1 power supply (optionally supply of multiple Single Gateways by 1 power supply).

Operation with short cable lengths with standard 24 V power supply possible.


" yes, max. 8 A/ASi network ":

Data decoupling integrated in the gateway. Cost-effective power for 2 ASi networks with 1 power supply (optionally supply of multiple Single Gateways by 1 power supply).

Operation with short cable lengths with standard 24 V power supply possible.


"yes, optimized for 2 x NEC class 2 power supplies"

Data decoupling integrated in the gateway. Optimized for use with 2 x UL certified 30 V/3 A power supplies with power limitation <100 W (BW4223). In combination 2 separate NEC Class 2 compliant ASi circuits are created.


"no, max. 8 A/ASi network, redundant supply ":

1 ASi power supply per ASi network. Gateway is powered in normal operation from one of the two ASi power supplies.

Should one ASi power supply fail, switching to the other ASi power supply allows all the diagnostics functions to be maintained and the unaffected ASi network continues to operate.


" no, max. 8 A/ASi network ":

1 ASi power supply per ASi network.

Integrated decoupling, ASi current measurement in the gateway

Access to ASi master and safety monitor via own software from Bihl+Wiedemann using the diagnostic interface (e.g. USB, RJ45, RS232). For certain devices with Ethernet-based fieldbus (PROFINET, EtherNet/IP), there is also the option of diagnostics and configuration directly via the fieldbus interface.

 

The latest version of the device description file of the gateway/gateway with integrated safety monitor (GSD, GSDML, EDS, etc.) is available in the "Downloads" section of the respective device.

Diagnostic and configuration interface

Detects whether the same address has been assigned to two ASi nodes. Frequent error when using a handheld addressing device.

Recognition of duplicate ASi addresses

Checks the ASi line for interference effects such as noise, external voltages, ...

ASi fault detector

Using a C-program offers the possibility to run mini-PLC functions with a gateway.

GE Digital Achilles® Robustness Test (Level 1 and 2, Version No.

Ethernet fieldbus interface (PROFINET, EtherNet/IP) and Ethernet diagnostic interface of the ASi-5/ASi-3 gateways are submitted to strict robustness testing via the Achilles Test Software to ensure robustness against vulnerabilities to cyber attacks. The field update capabilities of the gateway enable continuous firmware and security updates to continuously improve the functionality and robustness of the device.

PROFINET Master Simulator

The PROFINET Master Simulator is an easy to use software for data exchange with PROFINET devices of many suppliers.

 

The PROFINET Master Simulator can exchange data with many PROFINET devices even without a PROFINET Master. Furthermore the PROFINET Master Simulator also processes GSD-files as well as the input of special configurations to start the data exchange with PROFINET devices. Identification, renaming and address assignment of PROFINET devices is also possible.

 

Furthermore, the data, in particular the diagnostic function can be displayed binary, hexadecimal and now also as ASCII code. Output data can be transmitted consistently.

 

In jog mode, it is possible to keep outputs active for exactly as long as the mouse button is pressed. The PROFINET Master Simulator Plus additionally supports PROFIsafe modules, a log function for I/O data, and the transmission of acyclic data (Record Data CR).

 

However as the PROFINET Master Simulator is a monitoring and commissioning tool for PROFINET devices, it is not designed to control automation processes.
