    SYSMAC LINK System Communications Section 4-1 SYSMAC LINK System Communications SYSMAC LINK Units communicate through the SYSMAC LINK Network, a token bus LAN. This section describes the token bus communications used in the SYSMAC LINK Network. Token Bus Communications In token bus communications, individual nodes are connected to a main trunk line as a common bus line, as shown in the figure below.

  • Page 51: Setting Node Numbers

    Setting Node Numbers Section 4-2 When the control cycle is completed, the polling unit once again sends out the token, beginning the next token cycle. Together the token cycle and con- trol cycle make up the communications cycle, and the time required for the communications cycle is known as the communications cycle time.

    PC Mode at Start-up (C1000H only) Section 4-4 3. The token is passed from node to node according to node numbers, so the more dispersed the node numbers are, the greater distance the token has to travel. In optical fiber systems, the communications cycle time depends on the distance the token has to travel, so set node numbers according to the nodes positions in the network if possible.

SYSMAC LINK Units can receive but not transmit CV-mode commands. The data read/write services allow data transmission between nodes and distributed control. About Data Read/Write Services .

  • Page 88: About Data Read/Write Services

    NETWORK READ/WRITE Instructions Section 6-2 About Data Read/Write Services In addition to SEND(90) and RECV(98) instructions, a C-series PC equipped with a SYSMAC LINK Unit* can receive but not issue CV-mode commands. With these data read/write services, data can be transmitted between PCs and CVSS or CV-series PCs in the network and operation at other nodes can be controlled remotely.

    NETWORK READ/WRITE Instructions Section 6-2 Broadcasting Data It is possible to transfer the same data to all nodes in a network simultaneously by designating the destination node as 00. This transmission is called broad- casting. No responses are returned to broadcasts. (Broadcasting cannot be per- formed with the RECV(98) instruction.) Broadcast data Node 1...

    NETWORK READ/WRITE Instructions Section 6-2 4. Indirectly Addressed Beginning Reception Flag: The CV-series PC has a larger data area than the C-series PC. Therefore, the beginning reception word of the destination node cannot be always des- ignated by the operand of the SEND(90). If the beginning reception word cannot be designated, set the indirectly addressed beginning reception flag to 1 (ON: indirect addressing), in which case the second operand (D) will be the indirect beginning reception word, and it will be possible to designate the...

    NETWORK READ/WRITE Instructions Section 6-2 6-2-5 Response Codes When SEND(90) or RECV(98) is used in a SYSMAC LINK System, a response code is returned to indicate that the data transfer was completed successfully or identify the nature of the error when communications are not completed successfully.

    NETWORK READ/WRITE Instructions Section 6-2 6-2-6 Network Instruction Status Flags SEND(90) and RECV(98) are based on command/response processing. That is, the transmission is not complete until the sending node receives and acknowledges a response from the destination node. Operation without a response is also possible for SEND(90), if desired.
