Configuring the Adapter
Enabling Datalinks To Write Data
Parameters C153 [EN Data In 1] through C156 [EN Data In 4] control which
parameters in the drive, adapter, or any other connected peripheral receive values
from the network. To configure these parameters, set them to the drive parameter
number you want to write them to.
The following steps are required to enable Datalinks to write data:
1.
Set the values of only the required number of contiguous controller-to-
drive Datalinks needed to write data to the drive and that are to be
included in the network I/O connection.
2.
Reset the adapter by power cycling the drive.
After the above steps are complete, the adapter is ready to receive input data and
transfer status data to the master (controller). Next, configure the controller to
recognize and transmit I/O to the adapter. See
Enabling Datalinks To Read Data
Parameters C157 [EN Data Out 1] through C160 [EN Data Out 4] configure
which parameters in the drive, adapter, or any other connected peripheral send
values to the network. To configure these parameters, set them to the parameter
number you wish to read over the network.
The following steps are required to enable Datalinks to read data:
1.
Set the values of only the required number of contiguous drive-to-
controller Datalinks needed to read data from the drive and that are to be
included in the network I/O connection.
2.
Reset the adapter by power cycling the drive.
After the above steps are complete, the adapter is ready to send output data to the
master (controller). Next, configure the controller to recognize and transmit I/O
to the adapter. See

IMPORTANT
Always use the Datalink parameters in consecutive numerical order, starting
with the first parameter. For example, use parameters C153, C154, and C155 to
configure three Datalinks to write data. Otherwise, the network I/O connection
will be larger than necessary, which needlessly increases controller response
time and memory usage.
