5.1.3 Functional Specifications
DF1 ports
ƒ
Full and half duplex modes supported
ƒ CRC and BCC error checking
ƒ Full hardware handshaking control
ƒ User-definable module memory usage, supporting the storage and transfer of
up to 5000 registers to/from the control processor
ƒ Up to 125 word read and write command lengths supported
ƒ Floating point data movement supported
DF1 Master Protocol Specifications
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 SLC platform to act as a
SCADA sub-master.
ƒ
Command List: Up to 100 commands per Master port, each fully-configurable
for function, slave address, register to/from addressing and word/byte count
ƒ Status Data: Error codes available on an individual command basis. In
addition, a slave status list is maintained per active master port
ƒ Polling of Command List: User-configurable polling of commands, including
disabled, continuous, and on change of data (write only)
