Test items and divisions of responsibility

Test items include items to be performed by the partner manufacturer in advance and items to be performed by CLPA. Some items are tested by both the partner manufacturer and CLPA.
All test items at the partner manufacturer must be passed before testing at CLPA.

  • The conformance test is intended to assure that the product meets CC-Link IE TSN communication specifications, and not intended for device-specific functions.
  • Passing the conformance test does not mean that the performance or quality of the product itself are guaranteed.
  • Recommended wiring parts test can be applied to Ethernet Switches, cables, connectors, etc.
