Products Description of PLX31-EIP-PND
The PLX51-DF1-ENI is able to transfer data from a DF1 device to a maximum of eight Logix controllers. The module operates in one of four modes, simplifying the configuration for all applications.
| Operating Mode | Description |
|---|---|
| Message Initiator Bridge | Redirects DF1 PCCC messages to a Logix remote controller using a preconfigured EtherNet/IP path. Logix PLC mapping may be required. This mode also supports remote programming with RSLogix 5 and RSLogix 500. |
| DF1 Slave Remote Device | Converts DF1 PCCC messages into Logix controller tag read and write operations. No Logix PLC mapping configuration is required in this mode. |
| Scheduled Tag Transfer | Exchanges data between a DF1 device and multiple Logix controller tags based on a predefined schedule. No configuration changes are required on the Logix controller or the DF1 device. |
| Unscheduled Logix Messaging | Transfers data using messages initiated by Logix Message (MSG) instructions received by the gateway. |
Hereafter the PLX51-DF1-ENI will be referred to as the module.
The module can operate in both a Logix "owned" and standalone mode. With a Logix connection, the input and output assemblies will provide additional diagnostics information which will be available in the Logix controller environment.
The module uses isolated RS232 for DF1 communication providing better noise immunity. The RS232 port also uses a terminal block for convenient installation. The module can also be used in systems with redundant DF1 pathways.
A built-in webserver provides detailed diagnostics of system configuration and operation, including the display of received DF1 communication packets, without the need for any additional software.

What is the primary purpose of the PLX51-DF1-ENI module
+
-
The PLX51-DF1-ENI acts as a protocol gateway that connects DF1 serial devices with EtherNet/IP-based Logix controllers, enabling legacy Allen-Bradley equipment to communicate over modern Ethernet networks.
Where is the PLX51-DF1-ENI typically installed?
+
-
It is normally DIN-rail mounted inside a control cabinet, positioned between DF1 serial devices and the EtherNet/IP network for efficient wiring and simplified panel layout.
What are common symptoms of a failing PLX51-DF1-ENI
+
-
Common indicators include DF1 communication timeouts, failed PCCC messaging, loss of Ethernet connectivity, or abnormal LED status conditions on the gateway.
How is the PLX51-DF1-ENI configured?
+
-
Configuration is performed through the module's configuration interface using ProSoft tools. The gateway supports multiple operating modes, including DF1 slave, message initiator, and scheduled tag transfer.
