2.3. BD525 PROFIBUS-DP slave diagnosis

 

It is possible to check the diagnosis information, such as communication status, setting status and error information from the teaching pendant.

 

(1)   Select 『[F2]: System』 → 『2: Control parameter』 → 『2: Input/Output signal setting』 → 『15: BD525 fieldbus setting and diagnosis』.

 

(2)   Considering that the PROFIBUS-DP slave corresponds to the channel 3, use the 『[F3]: Previous』 or 『[F4]: Next』 key to move to the channel 3 and check the diagnosis information.
