5-26 Network Instructions
The network instructions are used for communicating with other PCs, BASIC
Units, or host computers linked through the SYSMAC NET Link System, SYS-
MAC LINK System, Ethernet System, or Controller Link System.
5-26-1 NETWORK SEND – SEND(90)
S: Source beginning word
IR, SR, AR, DM, HR, TC, LR
D: Destination beginning word
IR, SR, AR, DM, HR, TC, LR
Operand Data Areas
C: First control data word
IR, SR, AR, DM, HR, TC, LR

Limitations C through C+2 must be within the same data area and must be within the values
specified below. To be able to use SEND(90), the system must have a SYSMAC
NET Link, SYSMAC LINK Unit, PC Card Unit, or Controller Link Unit mounted.
Description When the execution condition is OFF, SEND(90) is not executed. When the
execution condition is ON, SEND(90) transfers data beginning at word S, to ad-
dresses specified by D in the designated node on the SYSMAC NET Link, SYS-
MAC LINK System, Ethernet System, or Controller Link System. The control
words, beginning with C, specify the number of words to be sent, the destination
node, and other parameters. The contents of the control data depends on
whether a transmission is being sent in a SYSMAC NET Link System, a SYS-
MAC LINK System, an Ethernet System, or a Controller Link System.
The status of bit 15 of C+1 determines whether the instruction is for a SYSMAC
NET Link System or a SYSMAC LINK/Ethernet/Controller Link System.
Control Data
Ethernet Systems Set the destination node number to 0 to send the data to all nodes. Refer to the
PC Card Unit Operation Manual for details.
