DF1

Supported Devices

The DF1/ABTCP protocol module can communicate with the Allen-Bradley® 1774-PLC, PLC-2, PLC-5 (excluding the PLC-5/250), PLC-5/VME, SLC-5/03, SLC-5/04, SLC-5/05, MicroLogix® 1200, 1500, and ControlLogix®. Other devices that use the same command function codes may also be supported.

Supported Features

The DF1/ABTCP protocol module provides support for reading from and writing to elements and sub-elements in any file in the device including the input, output, and status files. Version 4.1.0 and later support multi-bit reads for the PLC-5, SLC-5/03, /04, /05, PLC-2, 1774-PLC, MicroLogix® 1200, 1500, and ControlLogix®. Version 4.1.0 and later also support multi-bit writes for the PLC-5, PLC-2 and 1774-PLC. Version 4.1.6 and later support bit writes and multi-bit writes for the SLC-5/03, /04, /05. Version 4.2 and later support Word range write function, Word range read function, and Bit writes function for PLC-5. Version 4.2 and later also supports logical American Standard Code for Information Interchange (ASCII) addressing.

DF1 Over Ethernet

ACM supports DF1 communications over Ethernet including:

• Devices in which the final physical connection to the device is Ethernet . This is called EIP and is supported for most devices – see note below from Allen-Bradley® documentation. 
• Devices that support the legacy Allen Bradley Ethernet or CSPv4 (PLC5).
• Devices in which the final physical connection to the device is Serial (via an Ethernet-to-Serial converter).
