Assigning the TUNID on the engineering tool of the fail-safe controller

The TUNID must be assigned to the "Safety Supervisor" CIP Safety™ object via specific CIP services using service codes 0x56 (Propose_TUNID) and 0x57 (Apply_TUNID).

The following requirements must all be fulfilled for this purpose:

• The inverter is already integrated in the EtherNet/IP™ network in the engineering tool of the fail-safe controller.
• The IP address and the SNN of the inverter are configured in the engineering tool of the fail-safe controller.
• The inverter is configured with the IP address.
• The TUNID contains the delivery value (default value; all bytes 0xFF)
• The CIP Safety™ object reports the "Waiting for TUNID" state in online mode.

The TUNID must first be reset before it can be reused with another value. This can take place via the CIP Safety™ service "Safety Reset".
