Transfers data from the source words (S is
the first word) from node N of the specified
network (in a SYSMAC LINK or NET Link
System) to the destination words starting
at D. The format of the control words varies
depending on the type of system. In both
types of systems, the first control word (C)
gives the number of words to be
transferred.
For NET Link Systems, in the second word
(C+1), bit 14 specifies the system (0 for
system 1, and 1 for system 0), and the
rightmost 7 bits define the network
number. The left half of word C+2 specifies
the source port (00: NSB, 01/02: NSU),
and the right half specifies the source node
number.
For SYSMAC LINK Systems, the right half
of C+1 specifies the response monitoring
time (default 00: 2 s, FF: monitoring
disabled), the next digit to the left gives the
maximum number of re-transmissions (0
to 15) that the PC will attempt if no
response signal is received. Bit 13
specifies whether a response is needed
(0) or not (1), and bit 14 specifies the
system number (0 for system 1, and 1 for
system 0). The right half of C+2 gives the
source node number.
