Allen Bradley Driver Manual (pdf)

Allen Bradley devices are fully supported in the Hexatec software.  The options available ensures that the communications work with the widest possible range of Allen Bradley hardware, including PLCs, Programmable Automation Controllers and Drives.

In-built drivers mean no extra OPC server is required.  The connection method will usually be determined by existing installation, the drivers support a wide range of connection methods. 

Supported Allen Bradley Hardware

The Allen Bradley range includes:

Allen Bradley Connection Methods

Supported connection methods include:

Up to 8 adapters can be accessed in a single computer and adapters can access multiple devices as required.

Setup options depend on which method is being used.

Data table addressing covers a wide range of File Types to offer the maximum flexibility without the need to move / copy data in the hardware.

The flexible nature of the connection method configuration means that it is possible to address remote devices by routing through intermediate hardware and networks.

For minimal installations - say one SLC processor, it is possible make a single device connection simply by connecting to a serial port and using the DF1 protocol.  This can makes very cost effective small installations possible, without the need to purchase additional hardware or software.

Note: ensure that the connection method selected is supported by the hardware!

Data Types

A range of data types are supported including:

For data reads, either a regular poll is initiated on a tag group basis, or, for infrequently accessed points, tag groups can be refreshed on some other event. Data writes are performed per tag and are actioned as soon as possible after a tag value is changed.

For more details, refer to your PLC documentation or the extensive range of information available at the Allen Bradley website
