Allen-Bradley® Protocols
Overview
ACM supports communication with both legacy Allen-Bradley® Ethernet and Serial devices via the DF1 Protocol as well as newer Common Industry Protocol (CIP) based devices using the ControlLogix protocol.
Protocol Selection Table
Device Type | Communicating Through | Protocol (ACM) | Notes |
|---|---|---|---|
MicroLogix® 1000 MicroLogix® 1200 1774-PLC PLC-2 SLC-500 SLC-5/03/04 | Serial | DF1 | Uses classic DF1 addressing scheme |
PLC-5 SLC-5/05 | Serial/*Ethernet | DF1 | *Ethernet communication mode requires specific configuration settings on the device object. |
Micro 800® | Ethernet based models supporting EIP/CIP | ControlLogix | Tag based addressing with tag catalog discovery (Non-structured tags). |
MicroLogix® 1100 MicroLogix® 1400 MicroLogix® 1500 | Serial/*Ethernet | DF1 | *Ethernet communication mode requires specific configuration settings on the device object. |
CompactLogix® | Ethernet | ControlLogix | Tag based addressing with tag catalog discovery. |
CompactLogix® | Serial(Processor Port) | DF1 | Uses classic DF1 addressing scheme. |
ControlLogix® 1756 | Ethernet | ControlLogix | Tag based addressing with tag catalog discovery. |
ControlLogix® 1756 | Serial (Processor Port) | DF1 | Uses classic DF1 addressing scheme. |
Information
In general, the DF1 protocol should be used unless the device specifically adheres to the Logix5000® series CIP communication standard when using EtherNetIP or CSPv4 when using Allen Bradley Ethernet (Legacy).
