BWU5021ASi-3 PROFINET Gateway in stainless steel, 1 ASi-3 master

Communication interface between fieldbus and gateway:

interfaces for standardized fieldbus systems in industrial automation. Bihl+Wiedemann offers a wide range of gateways for common fieldbus interfaces:

• PROFIBUS
• PROFINET
• EtherNet/IP^TM + Modbus TCP
• BACnet/IP
• DeviceNet
• ControlLogix
• Compact-/MicroLogix
• EtherCat
• POWERLINK
• CC-Link
• CANopen
• RS 485 Modbus
• OPC UA server

The device communicates via the standard ASi-3 and/or ASi-5.

Standard devices

"Single Master":

1 ASi network, 1 ASi-5/ASi-3 Master.

1 ASi network, 1 ASi-3 Master.

"Double Master":

2 ASi networks, 2 ASi-5/ASi-3 Masters.

2 ASi networks, 2 ASi-3 Masters.

Safety devices

"Single Master" :

1 ASi network, 1 ASi-5/ASi-3 Master.

1 ASi network, 1 ASi-3 Master.

"Double Master" :

2 ASi networks, 2 ASi-5/ASi-3 Masters.

2 ASi networks, 2 ASi-3 Masters.

"Optional ASi Safety coupling circuit" :
2 ASi networks, 1 ASi-3 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.

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.

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

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

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