4.1 DF1 Functional Overview
The DF1 Master/Slave Protocol driver can exist in a single port (DFCM) or a
multiple port (DFCM3) implementation. In either case, the driver can be
configured on an individual port basis to operate as either a DF1 Master or a
Slave. Each port is independently configured for communication on a DF1
network and interfaces with the internal database in the module.
4.1.1 Master/Slave Serial Port(s)
The ProLinx module supports the DF1 protocol as a Master or Slave on up to
four ports. Each of the ports is individually configurable.
The relationship between the port labeling on the front of the ProLinx module and
the application is as follows:
Port Label Function
Debug Debug/Configuration
Following ports only exist on multiple port units
Port 1 DF1 Port 1
Port 2 DF1 Port 2
Port 3 DF1 Port 3
One or more DF1 protocol master ports can be configured on the module to
continuously interface with DF1 slave devices over a serial communication
interface (RS-232, RS-422 or RS-485). Each port is configured independently.
Support for half-duplex (master-slave) and full-duplex (point-to-point) DF1 links
are provided on the ports. User defined commands determine the commands to
be issued on each port. Up to 100 commands can be defined for each port. Data
read from the devices are placed in the virtual database. Any write requests for
the DF1 slave devices are sourced with data from the virtual database.
