General Notes
!
Warning
Your user program must first lock the input data of a slave (D_lock_in_slave_addr,
Section 4.3.1), then reset "req_mask" if data changes
(DPR_DATA_INT_CLEAR_AND_UNMASK), and then read the data itself.
Otherwise if events overlap, this may mean that the next data change goes
unnoticed.
Note 1
Your user program must reset the mask itself
(DPR_DATA_INT_CLEAR_AND_UNMASK).
Note 2
The memory area with index 127 contains the data of the slave module of the
CP 5614.
