Limitations Can be performed with the CPU11-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
execution 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
receive data to a node on the same Subsystem (i.e., network). Refer to the
SYSMAC NET Link System Manual for details.
