Master receive slots
Áctivate the receive slots from which the slave sends data (corresponding to the
settings in the slave).
In each of the 125µs cycles (slot 0...2, slot 3...7, slot 8...12, slot 13...17) data can
be received only via one slot, see also the
HEDA communication structure (see
page 396).
The assig

defined in the slave), this number is also received.
In the Wizard window "Receive Mapping table", it is defined under this mapping
table number where the data received are to be written to.
