Flags ER: The specified node number is greater than 126 in a SYSMAC NET Link
System or greater than 62 in a SYSMAC LINK System.
The sent data overruns the data area boundaries.
Indirectly addressed DM word is non-existent. (Content of :DM word is
not BCD, or the DM area boundary has been exceeded.)
There is no SYSMAC NET Link/SYSMAC LINK Unit.

Limitations Can be performed with the CPU31-E/33-E only. C through C+2 must be within
the same data area and must be within the values specified below. To be able to
use RECV(98), the system must have a SYSMAC NET Link or SYSMAC LINK
Unit mounted.
When the execution condition is OFF, RECV(98) is not executed. When the exe-
cution condition is ON, RECV(98) transfers data beginning at S from a node on
the SYSMAC NET Link/SYSMAC LINK System to words beginning at D. The
control words, beginning with C, provide the number of words to be received, the
source node, and other transfer parameters.
The status of bit 15 of C+1 determines whether the instruction is for a SYSMAC
NET Link System or a SYSMAC LINK System.
Control Data
SYSMAC NET Link Systems The source port number is always set to 0. Set the network number to 0 to re-
ceive data to a node on the same Subsystem (i.e., network). Refer to the
SYS-
MAC NET Link System Manual
for details.
