Specification table of CC-Link Ver. 1.10/Ver. 2.00

If the entire system consists of Ver. 1.10/Ver. 2.00 devices and Ver. 1.10 cables, that provides benefits as follows.

  1. The shortest inter-station cable length is 20 cm under all conditions.
  2. Flexibility of cable length reduces work on wiring and setting devices.
  3. With no extra cable length required when devices are put adjacently,
    you can use space effectively.
  4. Different brand cables can be used within a single system.
    If a system uses modules compatible with Ver. 1.00, 1.10 and Ver. 2.00,
    and cables compatible with Ver. 1.00 and 1.10,
    then follow the Ver. 1.00 specification for maximum overall cable
    extension length and inter-station cable length.
