CompactLogix/MicroLogix Fieldbus system
What is CompactLogix / MicroLogix?
CompactLogix and MicroLogix from Allen-Bradley are programmable logic controllers developed by Rockwell Automation which can be used for a variety of applications.
CompactLogix / MicroLogix ASi Gateway
Function
The Bihl+Wiedemann ASi Master connects a CompactLogix processor or a MicroLogix 1500 to an ASi network. Fast, easy set up into PLC backplane by the help of the new ASi Master. ASi I/O data and status information is mapped into the PLC processor’s I/O data.
ASi Scope
Diagnostics, which go far beyond the standard diagnostics facilitate the simple detection of the occasionally occurring configuration errors and further irritations towards the ASi communication. So in case of an error the down time of machines can be minimized or you can initiate preventive maintenance.
Commissioning and monitoring
The Bihl+Wiedemann ASi master BWU1416 for CompactLogix and MicroLogix 1500 is a type 1769 module. It is suitable for use with any CompactLogix and MicroLogix Controller that supports type 1769 modules. The ASi Master can be commissioned respectively parametrized with the help of the software "ASi Control Tools". Commissioning, debugging and setting up the system without the software can only be accomplished with the use of two push-buttons, the display and the LEDs directly on the system.

| Figure | Model | 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:
| 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. 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. 2 ASi networks, 2 ASi-5/ASi-3 Masters. 2 ASi networks, 2 ASi-3 Masters. | " 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.
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.
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.
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.
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. | Article No. |
