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 va-
ries 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 num-
ber. 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 dis-
abled), the next digit to the left gives the
maximum number of re-transmissions (0
to 15) that the PC will attempt if no re-
sponse signal is received. Bit 13 specifies
whether a response is needed (0) or not
(1), and bit 14 specifies the system num-
ber (0 for system 1, and 1 for system 0).
The right half of C+2 gives the source
node number.
