3.3. PROFINET IO-Device diagnosis

 

It is possible to use a teach pendant to check the diagnosis information such as communication state, setting state and error information.

 

(1)   Select 『[F2]: System』 → 『2: Control parameter』 → 『2: Input/Output signal setting』 → 『14: Real time Ethernet setting and diagnosis』.

 

(2)   As the PROFINET IO-Device corresponds to the channel 3, use the 『[F3]: Previous』 or 『[F4]: Next』 key to shift to the channel 3.
