No multiplex feature for DSE-channel

Kuka · KRC2 KSS System Message

What does 344 mean?

Force mode is activated, but the RDC (Robot Drive Controller) does not have the required plug-on card for multiplex operation. Consequently, force mode will not be activated.

Common Causes

  • Attempted to use a multiplex feature on a DSE-channel which does not support it.
  • The specific DSE-channel hardware or software configuration does not allow for multiplexing.
  • Feature not enabled or available for the current channel setup.
