Rockwell Automation 20-COMM-S RS-485 DF1 Adapter - Manual (Page 28)

3-8 Configuring the Adapter
The following parameters provide information about how the adapter is
configured. You can view these parameters at any time.
Viewing the Adapter Configuration
Number Name Description
01 DPI Port The port on the drive to which the adapter is connected. Usually, it is
on Port 5.
02 DPI Data
Rate The data rate used by DPI in the drive. It is set in the drive, and the
adapter detects it.
04 DF1 Addr Act The node address used by the adapter. This will be one of the
following values:
• The address set by the Node Address switches.
• The value of Parameter 03 - [DF1 Addr Cfg] if the switches
have been disabled.
• In order for either of the above to take effect, the adapter has to
be reset or power cycled.
06 DF1 Rate Act The data rate used by the adapter. This will be one of the following
values:
• The data rate set by the Data Rate switch.
• The value of Parameter 05 - [DF1 Rate Cfg] if the switches
have been disabled.
• In order for either of the above to take effect, the adapter has to
be reset or power cycled.
07 Ref/Fdbk Size The size of the Reference/Feedback (16 bits or 32 bits). It is set in
the drive and the adapter automatically uses the correct size.
08 Datalink Size The size of the Datalinks (16 bits or 32 bits). It is set in the drive and
the adapter automatically uses the correct size.
11 Active Cfg Source from which the adapter node address and data rate are
taken. This will be either switches on the adapter or parameters in
EEPROM. It is determined by the settings of the switches on the
adapter.
13 DPI I/O Act The I/O used by the adapter. This value is the same as
Parameter 13 - [DPI I/O Config] unless the parameter was
changed and the adapter was not reset.
Bit Definitions
0 = Cmd/Ref
1 = Datalink A
2 = Datalink B
3 = Datalink C
4 = Datalink D
5 = Not Used
6 = Not Used
7 = Not Used
25 CRC/BCC Act Actual Checksum or CRC selection.
26 Dup Msg
Detect Determines if the adapter ignores messages with duplicate TNS
IDs. Normally set to Enable (default). Set to Disable if using a
ProSoft 3150-DFM module or any device which does not increment
the TNS ID.
