CC-Link V1.10/V2 Specifications

If the entire system consists of V1.10/V2 devices, this provides benefits as follows:

If the entire system consists of V1.10/V2 devices, this provides benefits as follows:
  • 1.The shortest inter-station cable length is 20 cm under. (when using cable Version 1.10)
  • 2.Flexibility of cable length reduces work when wiring devices.
  • 3.When devices are mounted adjacent to one another, there is no extra cable required, therefore you can use space more efficiently
  • 4.Different brand cables can be used within a single system. If a system uses device stations compatible with Version 1.00, 1.10 and 2.00, and cables compatible with cable Version 1.00 and 1.10, then follow the cable Version 1.00 specification for maximum overall cable extension length and inter-station cable length.
