Micrologix 1500 LRP – Intellution ABR Driver Configuration

11/2/04

This document describes how to setup a Micrologix PLC to communicate to a host computer
using the Intellution ABR driver.

Hardware

A null modem cable was used between the host computer and Channel 1 of the Micrologix PLC.
Channel 0 was used for programming.

 

Micrologix Communications Configuration

This is the channel configuration as set up in RSLogix 500.

(Project>Controller>Channel Configuration>Channel 1)

This configuration assumes that remote communications uses Channel 1 of the Micrologix
processor. The node address is 21 decimal.

RSLinxCommunications Configuration

The following screenshots show the polling master configuration as set in RS-Linx.

(Communications>Configure>AB_MASTR-1)

This configuration assumes that remote communications uses Com 1 of the host computer.
The polling list must contain the node addresses of the PLC’s you want to poll. In this
example, the remote node address is entered as 21 decimal.

 

Intellution Fix ABR Driver Configuration

(SCU>ABR)

Channel Configuration

The channel configuration references the driver name as entered in RS-Linx (here as
AB_MASTR-1).

Device Configuration

The device name can be anything (here this is PLC21). This name will be used as the device
name in the Intellution database.

One thing that is potentially confusing here is that the device address must be entered as
an octal number. Everywhere else it is entered as a decimal number. (Here: 21 decimal =
25 octal).

Block Configuration

The block name can be anything (here this is DataBlock0). The Intellution database use
the actual address in the format: Device Name:File:Word:[Bit]

Intellution Database Builder

The device is ABR, the name of the driver. The I/O address is entered in the format of:
Device:File:Word:[Bit]

Here, the address is N7:0/1 of the PLC at node address 21 decimal.
