Allen-Bradley PLC Network Interface
This document explains how to configure the subject interface for Machine Connect.
Setup
1. Create a new "point" type Asset Class representing the “System” (you may name it anything. for example "ALLEN BRADLEY INTERFACE CLASS"). Note: asset class attributes are not required.
2. Associate the Asset Class with a business line.
3. Create a new Asset derived from the asset class created in step 1. Note the "asset key" shown in the attributes section of the asset details page. This will be used later when you install Machine Connect.
4. Create a new Workflow Class for that will tell MC what data to collect. You will create one workflow for each collection of data points collected at a given frequency (for example "Hourly SCADA data" or "15 Minute Data").
5. Check the “Machine Connected” checkbox.
6. Associate the workflow with the same “Business Line” as the asset class created above.
7. Associate the workflow with the asset class.
8. Define one workflow field for each tag you'd like MC to query as follows:
SLC/PLC5/Micrologix
| Type | Required | Key | Title | Description |
|---|---|---|---|---|
| TEXT | Yes | AB Legacy|{IP ADDRESS:PORT}|{FAMILY}|{MEMORY-ADDRESS} | Friendly name for the tag | Friendly description for the tag |
{FAMILY} options: (0 = PLC5; 1 = SLC500; 2 = MicroLogix). Any key not found in this format will be ignored and not be included in the final report.
Examples:
AB Legacy|192.168.125.15|1|F211:202 |
AB Legacy|192.168.125.15|1|F211:236 |
AB Legacy|192.168.125.17:999|2|F21:237 |
ControlLogix
| Type | Required | Key | Title | Description |
|---|---|---|---|---|
| TEXT | Yes | AB Control Logix|{IP ADDRESS}|{PORT}|{PLCTAGNAME} | Friendly name for the tag | Friendly name for the tag |

NOTE: Interface related data is specified at the "field-level" for this interface type. In other words, the location and details of the data point is defined in its field key as show above.
