Features and Benefits

  • Single-slot, 1769 backplane-compatible
  • The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module.
  • Ladder Logic is used for data transfer between module memory and processor controller tags. A sample ladder file with AOI is included.
  • Configuration data obtained from configuration text file downloaded to module. A sample configuration file is included.
  • Supports CompactLogix and MicroLogix 1500 LRP Controllers except 1769-L23E-QBFC1B, 1769-L16x, and 1769-L18x.


Functional Specifications

  • Full and half duplex modes supported
  • CRC and BCC error checking
  • Full hardware handshaking control provides radio, modem and multi-drop support
  • User-definable module memory usage, supporting the storage and transfer of up to 4000 registers to/from the control processor
  • 125-word read and write command lengths supported
  • Floating-point data movement supported
  • The ports on the DF1 module can be individually configured as Master ports. When configured in Master mode, the DFCM module is capable of reading and writing data to remote DF1 devices, enabling the CompactLogix/MicroLogix platform to act as a SCADA sub-master.
  • Command List: Up to 100 commands per Master port, each fully configurable for function, slave address, register to/from addressing and word/byte count
  • Status Data: Error codes available on an individual command basis. In addition, a slave status list is maintained per active Master port
  • Polling of Command List: User-configurable polling of commands, including disabled, continuous, and on change of data (write only)
  • The module accepts DF1 commands from an attached DF1 Master unit. When in slave mode, the module can accept DF1 commands from a Master to read/write data stored in the module’s internal registers. This data can be derived from other DF1 slave devices on the network through a Master port or from the processor and is easily transferred to the processor’s data registers.
  • Several hardware connections have been tested by ProSoft or have been customer field tested. The following physical connections have been tested successfully:
  • RA Panel View (Full duplex point-to-point, DFCM as slave)
  • RA Processors (Full/half duplex, DFCM as either Master or slave)
  • RA Power Monitors (485 half-duplex, DFCM as Master)
