4.8 Viewing the Module Configuration
The parameters in table 4.4 provide information about how the
module is configured. You can view these parameters at any time.
Table 4.4 – Module Configuration Status Parameters
No. Name Description
01 DPI Port The port to which the module is connected. This will usually be
port 5.
02 DPI Data Rate The data rate used by the drive. This data rate is set in the
drive and the module detects it.
04 DF1 Addr Actual The node address actually used by the module. This will be
one of the following values:
• The address set by the Node Address switches on the
module.
• The value of module parameter 3 (DF1 Addr Cfg) if the
switches have been disabled.
06 DF1 Rate Actual The DF1 data rate actually used by the module. This will be
one of the following values:
• The data rate set by the Data Rate switch on the module.
• The value of module parameter 5 (DF1 Rate Cfg) if the
switches have been disabled.
07 Ref/Fdbk Size The size of the Reference/Feedback (16 bits or 32 bits). It is
set in the drive and the module 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 module automatically uses the correct size.
11 Active Cfg The source from which the module address and data rate are
taken. This will either be switches on the module or
parameters in EEPROM. It is determined by the switch
settings on the module.
13 DPI I/O Active The I/O used by the module. The value of this parameter will
be equal to the value of module parameter 12 (DPI I/O Config)
unless the parameter was changed and the module 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 The actual error-checking method selected.
26 Dup Msg Detect Determines if the module ignores messages with duplicate
TNS IDs. Normally set to Enable (default). Set to Disable if
using a ProSoft 3150-DFM module or any device that does not
increment the TNS ID.
