Allen-Bradley DF1 Protocol

The Allen-Bradley DF1 protocol works in tandem with the Autosol Communication Manager^® (ACM) software to bring companies accurate, real-time and reliable information when it is needed the most.

Allen-Bradley DF1 is typically used for higher-speed data monitoring where frequent data updates are required. Similar to its counterpart, the Allen-Bradley ControlLogix protocol, the protocol is used almost exclusively for high-speed data monitoring in manufacturing operations – namely oil and gas industries.

The Allen-Bradley DF1 works to ensure that you are delivered information nearly instantaneously in Real Time, as most units typically do not have archiving history capability in its hardware.

ACM can poll data from Programmable Logic Controllers (PLCs) by using the DF1 protocol. The data is then sent back from the device and can be provided for operator control screens in any Human Machine Interface (HMI) environment that supports OPC.

Allen-Bradley DF1 is one of the many protocols ACM is compatible with to help make SCADA environments more manageable and more organized to ensure structured operation through an HMI. The HMI software is typically an OPC client application which can request data from the OPC server — or ACM.

Allen-Bradley DF1 Protocol and ACM

ACM works to deliver protocol data to employees, such as control room engineers and SCADA managers, by speaking to the DF1 device in its native protocol. Employees can obtain data from the field by using ACM to deploy a request for data from the Allen-Bradley DF1. That data is then fed back into the control room through its common protocol, Object Link and Embedding for Process Control (OPC), as ACM is an OPC server.

Autosol Communications Manager (ACM) extends companies’ SCADA systems abilities

For over 30 years, AUTOSOL (Automation Solutions) has been building custom drivers to ensure the efficient and reliable transfer of commands, programs, data and information between control systems and endpoint SCADA devices like PLCs and RTUs. ACM speaks to devices in their native protocols to enable communication between incompatible devices, making it easy to add PLCs, including Allen-Bradley DF1, to a SCADA system and ensuring information is consistently being communicated.

Because ACM isn’t dedicated to one specific protocol, your DF1 devices are able to interact. Companies will reap the benefits the Allen-Bradley DF1 offers while saving costs associated with having to update an entire SCADA system to devices that speak the protocol.

As a leader in the industry, AUTOSOL takes communication between devices seriously. Combining the flexibility of AUTOSOL’s ACM and custom drivers means companies are not obligated to construct and update a SCADA system with one brand and its protocols. With our leading products and equipment your protocol will be able to transmit and receive data from all other SCADA devices.
