4-8 EtherNet/IP Communications Module
4.5 Setting the Data Rate
By default, the module is set to autodetect, so it automatically
detects the data rate and duplex setting used on the network. If you
need to set a specific data rate and duplex setting, the value of
module parameter 16 (EN Rate Cfg) determines the Ethernet data
rate and duplex setting that the module will use to communicate. For
definitions of data rate and duplex, refer to the Glossary.
Step 1. Set the value of parameter 16 (EN Rate Cfg) to the data
rate at which your network is operating as shown in figure
4.10.
Important:Auto detection of baud rate and duplex works properly
only if the device (usually a switch) on the other end of
the cable is also set to auto detect the baud rate/duplex.
If one device has the baud rate/duplex hard coded, the
other device must be hard-coded to the same settings.
Step 2. Reset the module. Refer to Resetting the Module in
section 4.11.
4.6 Setting the I/O Configuration
The I/O configuration determines the data that is sent to and from
the drive. Logic Command/Status, Reference/Feedback and
Datalinks may be enabled or disabled.
Step 1. Set the bits in module parameter 23 (DPI I/O CFG) as
shown in figure 4.11. A “1” enables the I/O. A “0” disables
the I/O. Bit 0 is the right-most bit. In figure 4.11, it is
highlighted and equals “1”.
