Getting Started Allen Bradley

Open Automation Software Tags can be defined to connect directly to Allen Bradley controllers with the built in ABLogix and ABClassic Driver Interfaces which support communications over Ethernet to ControlLogix, CompactLogix, GuardLogix, and Micro800 with the ABLogix driver, and MicroLogix, SLC 500, and PLC-5 with the ABClassic driver. The following steps can be used to setup direct communications with Allen Bradley controllers.

Configuring the Default Network Adapter

If the communications for the Allen Bradley driver is not working at all you may need to set the default network adapter priority in the operating system.
