(a) Use this function block when the DN611 is in run mode.
(b) When REQ is TRUE, data is input and output to and from the DN611 specified by
CH, UNIT, and SLOT. Data from two or more slave devices can be sent or
received because an input/output data area can be specified.
(c) Of the output data to the slave device written in WRITE_DT, the number of words
corresponding to N_WPOL are written in the polling output data area of the
DN611 and 4 words (fixed) in its bit strobe output data area.
WPOL[0] to WPOL[377] amd WBS[0] to WBS[3] correspond to the polling output
data area/bit strobe output data areas as shown in the table below.
Write them as appropriate to the specifications of the slave devices you are
using.

(d) Of the data input to a slave device and read into the polling/bit strobe input data
area of the DeviceNet module, the number of words corresponding to N_RPOL
are read to READ_DT.
RPOL[0] to RPOL[127] corresponding to the polling/bit strobe input data areas as
shown in the table below.

(e) This function block operates as described in the table below depending on the
DN611 operation mode (synchronous/asynchronous, polling/bit strobe).
