Description
The function is activated when
ENABLE
switches to
TRUE
. The
DPM_MSAC1_READ function block requests a data block of a SLAVE_ADD
slave communicating with the master on the acyclic channel. The data selection is
determined by
SLOT
and
INDEX
. The
LENGTH
indicates the length of the data
block to be expected.
READ_LEN
outputs the length actually read.
If
LENGTH
is smaller than
READ_LEN
, an error is output on the
ERROR
output.
