The ProLinx DF1 Serial Port Expander Gateway allows you to attach up to three separate DF1 master devices to a single DF1 slave.
The module is designed to act as a multiplexer, allowing simultaneous connections from multiple DF1 masters to a single DF1 slave. A common use for the module is to have an HMI panel, SCADA software, and Programming software all communicating to the same DF1 channel 0 port of the Rockwell Automation processor.
The module provides a single DF1 Master port and three DF1 Slave ports.
The Serial Port Expander adds three additional slave ports for a DF1 based device. This allows users to connect programming software, HMI, and modems to processors simultaneously. Commands from the host devices are passed through the module and routed directly to the front port of the processor. This allows a processor's port to be expanded to allow communication with a variety of devices at the same time. Typical applications include local ladder configuration, local operator interface, and wireless concentrator for remote programming and data collection.
The DF1 Master/Slave Protocol driver provides extensive support for both Master and Slave implementations of the protocol. The serial port on the gateway is user-configurable to support the DF1 protocol (Master or Slave, Error Checking, Baud rate, etc).

Command List |
Up to 100 commands per Master port, each fully-configurable for function, slave address, register to/from addressing and word/bit count |
Polling of Command List |
User-configurable polling of commands, including disabled, continuous, and on change of data (write only) |
The ports on the module can be individually configured to support the Slave mode of the DF1 protocol. When in slave mode, the module can accept DF1 commands from a master to read/write data stored in the module's internal registers.
