High-Performance Connectivity for PLC5/SLC500/MicroLogix Compliant Controllers
This driver is included in the following TOP Server driver suites:
Up to 100 communication channels supported.
Devices per channel for scalable deployments.
Wide serial port range for flexible setups.
Supports DF1, DH Plus, DH 485, and more.
The Rockwell Allen-Bradley DF1 driver works in conjunction with TOP Server to provide data exchange between OPC UA, OPC DA, SuiteLink and DDE clients and Allen-Bradley PLC-5, SLC, and MicroLogix devices using the Allen-Bradley DF1 protocol, including classic KF2 and KF3 interfaces, the 1784-U2DHP DH+ converter, Ethernet Encapsulation & more. Full device, protocol & network details are found on this page.
This driver supports complex function blocks in the MicroLogix 1200/1500 PLCs, Full Duplex mode, and Half Duplex and Radio modem operation for wide area radio modem links for all PLC types.
This driver does not require a Rockwell Automation RSLinx license.
Allen-Bradley DF1 Serial — This driver is available in the following TOP Server driver suites: TOP Server Allen-Bradley Suite, TOP Server Manufacturing Suite.
Proven benefits that help you deploy faster and operate more reliably
Direct connectivity without Rockwell RSLinx license
Supports all PLC5 and SLC file types and data types
User-definable block sizes and configurable delays
Simultaneous communication with multiple PLCs
"The DF1 driver's support for both Full and Half Duplex modes has been perfect for our mixed PLC environment. We're running PLC-5 and MicroLogix controllers without any issues."
