Chapter 3 Configuring the Adapter
1. Set the values of only the required number of contiguous drive-to-network
Datalinks needed to write data to the network and that are to be included
in the network I/O connection.
2. Reset the adapter; see Resetting the Adapter on page 36 .
After the above steps are complete, the adapter is ready to send output data and
transfer status data to the master (controller). Next, configure the controller to
recognize and transmit I/O to the adapter. See
Configuring the I/O on page 39 .
Enabling Datalinks To Read Data
Host parameters C161 [Opt Data In 1] through C164 [Opt Data In 4]
configure which parameters in the drive receive values from the network. To
configure these parameters, set them to the parameter number you wish to
correlate them to.
The following steps are required to enable Datalinks to read data:
1. Set the values of only the required number of contiguous network-to-drive
Datalinks needed to read data from the network and that are to be
included in the network I/O connection.
2. Reset the adapter; see Resetting the Adapter on page 36 .
After the above steps are complete, the adapter is ready to receive input data from
the master (controller). Next, configure the controller to recognize and transmit
I/O to the adapter. See
Configuring the I/O on page 39 .
Setting a Fault Action By default, when communications are disrupted (the network cable is
disconnected) and/or the controller is idle (in program mode or faulted), the
drive responds by faulting if it is using I/O from the network. You can configure a
different response to these events:
• Disrupted I/O communication by using Device parameter
23 [Comm Flt Action] .
IMPORTANT Always use the Datalink parameters in consecutive numerical order, starting
with the first parameter. For example, use Host parameters C161, C162, and
C163 to configure three Datalinks to read data. Otherwise, the network I/O
connection will be larger than necessary, which needlessly increases controller
response time and memory usage.
