A.8 DF1 Interface (P/N1295-0343)
This module emulates the DF1 slave functionality of
an Allen-Bradley SLC 5/03 DF1 port. It responds to
queries for data from the N14 integer file by sending
alarm, fault, and concentration data.
The DF1 protocol is defined by the Allen-Bradley
DF1 Protocol and Command Set Reference Manual
which can be downloaded from
rockwellautomation.com/idc/groups/literature/
documents/rm/1770-rm516_-en-p.pdf.
Technical information on the ProSoft Technology
MVI46-DFCM interface which is used in the Vertex M
can be found at http://www.prosoft-technology.com.
The baud rate and address of the DF1 interface are
set using the configuration profile utility as described
in See
Section 3.6 Configuration
speeds range from 1200 to 57,600 baud with a default
of 19,200. The DF1 address can be set from 2 to 127.
The data map used by the DF1 interface is shown
in
Table
A-5. This appears as the N14 file. The
interpretation of the data is in
Appendix A - Network Interface and Options
