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.

Products

CompactLogix / MicroLogix AS-i Gateway

Function

The Bihl+Wiedemann AS-i Master connects a CompactLogix processor or a MicroLogix 1500 to an AS-i network. Fast, easy set up into PLC backplane by the help of the new AS-i Master. AS-i I/O data and status information is mapped into the PLC processor’s I/O data.

 

AS-i Scope

Diagnostics, which go far beyond the standard diagnostics facilitate the simple detection of the occasionally occurring configuration errors and further irritations towards the AS-i 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 AS-i 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 AS-i Master can be commissioned respectively parametrized with the help of the software "AS-i 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.

Standard devices

"Single Master":

1 AS-i network, 1 AS-i Master.

"Double Master":

2 AS-i networks, 2 AS-i Masters.

Safety devices

"Single Master":
1 AS-i network, 1 AS-i Master.

"Double Master":
2 AS-i networks, 2 AS-i Masters.

"Optional AS-i Safety coupling circuit":
2 AS-i networks, 1 AS-i Master.

Number of AS-i networks, number of AS-i Master

"yes, max. 4 A/AS-i network":
Cost-effective power for 2 AS-i 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.


"no, max. 8 A/AS-i network, redundant supply":
1 AS-i power supply per AS-i network. Gateway is powered in normal operation from one of the two AS-i power supplies.

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

"no, max. 8 A/AS-i network":

1 AS-i power supply per AS-i network.

1 power supply, 1 gateway for 2 AS-i networks, inexpensive power supplies

"USB":

Access to AS-i Master and Safety Monitor with Bihl+Wiedemann proprietary software by using the USB interface.

"Ethernet fieldbus"

Access to AS-i Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet fieldbus interface.

"Ethernet fieldbus + Ethernet diagnostic":

Access to AS-i Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet diagnostic interface or Ethernet fieldbus interface.

"Ethernet diagnostic":

Access to AS-i Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet diagnostic interface.

"Ethernet diagnostic + Modbus TCP diagnostic":

Access to AS-i Master and Safety Monitor with Bihl+Wiedemann software or via Modbus TCP by using the Ethernet diagnostic interface.

For a full-fledged Modbus TCP fieldbus interface use one of our Modbus TCP gateways in stainless steel or Modbus TCP gateways with integrated safety monitor.

"Ethernet fieldbus + RS 232":

Access to AS-i Master and Safety Monitor with Bihl+Wiedemann software by using the Ethernet fieldbus interface or by using an adapter cable via RS 232 interface.


"RS 232":

Access to AS-i Master and Safety Monitor with Bihl+Wiedemann software by using an adapter cable via RS 232 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 AS-i slaves. Frequent error when using a handheld addressing device.

Recognition of duplicate AS-i addresses

Checks the AS-i line for interference effects such as noise, external voltages, ...

AS-i fault detector

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