Omron CS1W-CLK21 controller link unit module cpu bus
Omron CS1W-CLK21 Controller Link Unit
Units were pulled from a working environment, and appear to be in very good shape, however they are untested.
Wired (shielded twisted-pair cable)
Flag synchronization (conforms to HDLC frames)
Maximum transmission speed/distance
Maximum distance between nodes
Specified shielded twist-pair cable. Two signal wires, one shield
PLC: Connection to terminal block. Computer: Connection using special connector
CX-Integrator in CX-One, CX-Net in CX-Programmer3, and Programming Console
Data links and message service
Send words per node: 1,000 words max.
Number of send/receive words per node: 12,000 words max.
Total number of send words per network: 62,000 words max.
PLC: Bit areas (CIO Area, Work Area, Link Area5), Data Memory (DM), Extended DM Area (EM)
Computer: FinsGateway event memory
2,012 bytes max. (including the header)
Self-diagnosis function (hardware checking at startup)
Echoback test and broadcast test (using the FINS command)
CRC check (CCITT X16+X12+X5+1)
2. With wired models, the maximum number of nodes is 32 if Repeater Units are not used. A Repeater Unit is required when building a network with more than 32 nodes. If a Repeater Unit is used, be sure to use only the following Controller Link Units or Boards and set the Wired Network 62 Node Enable Bit in the DM Parameter Area software switches at all nodes.
3. CX-Net in CX-Programmer version 3.1 or earlier can be used only in a system with a maximum of 32 nodes (node address 1 to 32). If a system is to be used with a maximum of 62 nodes (node addresses 1 to 62), use CX-Net in CX-Programmer version 3.2 or higher or the CX-Integrator.
