    The SYSMAC LINK supports data links that enable data sharing and a mes- sage service that enables sending and receiving data when required. Data link words can be freely set to create a flexible data link system and effectively use memory areas.

    In the event of an error or failure in the polling node, another node automati- cally takes over management of the SYSMAC LINK System without stopping the entire network. The CX-Net within the CX-Programmer can monitor and/or program PLCs anywhere in the network via the SYSMAC LINK System.

    To avoid having two nodes attempt to transmit simultaneously, only one node has the right to transmit at a time. The right to transmit is held by the node that holds what is called the token, which is passed in sequence from node to node, beginning with the node with the lowest node address (the polling node, see below).

  • Page 52: Unit Number

    (2) Turn OFF the PLC when setting the rotary switches. (3) If the unit number of any node has been changed, the I/O table on the PLC must be generated again and that node must be turned ON after all other nodes have been turned ON.

  • Page 53: Network Address Setting

    (1) Always turn OFF the PLC power before setting or changing node ad- dress. (2) If the node address set on the Unit is outside of the allowed range (01 to 62), a communications error will occur and the red ERC indicator will light on the Unit.

    When manual settings have been made, data link areas will be refreshed for all nodes specified in the refresh parameters. In the following example, only nodes 3, 4, 6, and 7 are participating in the data links. Nodes 1, 2, 5, and 8, however, will also be refreshed and words for them cannot be used for other applications.

  • Page 70: Data Link Table Example

    In this example, the refresh parameters differ from node to node, so the data link tables will also differ from node to node. There are four nodes in the net- work (2, 5, 6, and 8), but some nodes will not receive data from all other nodes.
  • Page 71 When setting data link tables for CS-series SYSMAC LINK Units with CX-Pro- grammer Ver. 1.2 (Service Pack 1), set the PLC type to CV/CVM1. With CX- Programmer Ver. 2.0 or later, it is possible to set a CS-series PLC type.
