In order to retrieve data from the modules database register 200, the remote
master would issue a command using the address N8:0. In order to interface with
database base register 405, the remote master would use the address N9:5. The
following table outlines the complete file emulation for the module:
Register Range File Start File End Content Size
0 to 4999 N7:0 N31:199 User Data 5000
5000 to 5009 N32:0 N32:9 Backplane Configuration 10
5010 to 5039 N32:10 N32:39 Port 1 Setup 30
5040 to 5069 N32:40 N32:69 Port 2 Setup 30
5070 to 5199 N32:70 N32:199 Reserved 130
5200 to 6399 N33:0 N38:199 Port 1 Commands 1200
6400 to 7599 N39:0 N44:199 Port 2 Commands 1200
7600 to 7700 N45:0 N45:199 Misc. Status Data 200
7800 to 7999 N46:0 N46:199 Command Control 200
8000 to 9999 N47:0 N56:199 Reserved 2000
All the data in the module is available to a remote host. This permits the host
device to remotely configure the module and view the status data.
Master Driver Mode
In the Master mode, the MVI69-DFCM module is responsible for issuing read or
write commands to slave devices on the DFCM network. These commands are
user configured in the module via the Master Command List received from the
CompactLogix or MicroLogix processor or issued directly from the CompactLogix
or MicroLogix processor (event command control). Command status is returned
to the processor for each individual command in the command list status block.
The location of this status block in the module's internal database is user defined.
The following flow chart and associated table describe the flow of data into and
out of the module.
