Section 5-23 SYSMAC NET Link/SYSMAC LINK Instructions IORF(97) can be used to refresh I/O words allocated to the CPU or an Expansion I/O Rack only. It cannot be used for other I/O words. Limitations St must be less than or equal to E. Description When the execution condition is OFF, IORF(97) is not executed. When the execution condition is ON, all words between St and E will be refreshed. This will be in addition to the normal I/O refresh performed during the CPU’s cycle. Execution Time The execution time for IORF(97), TIORF, is computed as follows: TIORF = 1 ms + (130 µs x number of words refreshed) Flags 5-23 There are no flags affected by this instruction. SYSMAC NET Link/SYSMAC LINK Instructions The SYSMAC NET Link/SYSMAC LINK instructions are used for communicating with other PCs linked through the SYSMAC NET Link System or SYSMAC LINK System. These instructions are applicable to the CPU11-E only. 5-23-1 NETWORK SEND – SEND(90) Operand Data Areas Ladder Symbols S: Source beginning word SEND(90) @SEND(90) S S D D C C IR, SR, AR, DM, HR, TC, LR D: Destination beginning word IR, AR, DM, HR, TC, LR C: First control data word IR, AR, DM, HR, TC, LR 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 SEND(90), the system must have a SYSMAC NET Link or SYSMAC 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 addresses specified by D in the designated node on the SYSMAC NET Link/ SYSMAC 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 or a SYSMAC 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 System. Control Data SYSMAC NET Link Systems The destination port number is always set to 0. Set the destination node number to 0 to send the data to all nodes. Set the network number to 0 to 211
