Program … Communication … Comm addressing … Comm read
addressing … SCAN_RCV01_AS – SCAN_RCV10_AS should be set as
needed to reference the desired command words. Any unused addresses
should be programmed as DUST. These parameters correspond to parameter
numbers 1 - 10 when configured in the interface’s point database (refer to
section 15.3). Note that although all 10 of these parameters (#1 - #10) can be
written via the interface at any time, only SCAN_R_SIZE number of parameters
will be recognized by the drive.

4.3 Write (Status) Data Configuration

Program … Communication … Comm addressing … Comm write
addressing … SCAN_W_ADRS can be set to any value between 10 and
1010. A value of 10 is recommended.

Program … Communication … Comm addressing … Comm write
addressing … SCAN_W_SIZE must be set to the number of status items the
drive is to transmit. For example, if only four status words are to be received
from the drive, then this value can be set to 4. This will enable the first four
SCAN_WRxx_AS parameters, which are numerically indexed via the interface as
parameters #11 through #14 (refer to section 15.3). Note that there is no
penalty in setting this parameter to its maximum value (25). Also note that any
parameter indexes larger than SCAN_W_SIZE that are accessed via the
interface will always return value of 0. For example, if SCAN_W_SIZE is set to a
value of 5 and ASD parameter #17 (corresponding to SCAN_WR07_AS) is
accessed via the network, then the value returned will always be 0.

Program … Communication … Comm addressing … Comm write
addressing … SCAN_WR01_AS – SCAN_WR25_AS should be set as needed
to reference the desired status words. Any unused addresses should be
programmed as DUST. These parameters correspond to parameter numbers
11 - 35 when configured in the interface’s point database (refer to section 15.3).
Note that although all 25 of these parameters (#11 - #35) can be read via the
interface at any time, only SCAN_W_SIZE number of parameters will contain
actual data.
