r2054 PROFIBUS status / PB status

Description: Status display for the PROFIBUS interface.

3:
4:
Note: Re r2054 = 3:
In state 3 (the LED flashes green), a cyclic connection has been established to the PROFIBUS master; however,
one of the following prerequisites is missing for cyclic operation:
- No setpoints are being received as the PROFIBUS master is in the STOP condition.
Only for clock-cycle synchronous operation:
- The drive is not in synchronism as the global control (GC) has an error.
- The master sign-of-life (r2050[3], r2093.12-15) is not being correctly received on a drive object SERVO. Possible
causes:
- the sign-of-life is completely missing.
- the sign of life is not incremented in the Tmapc (r2064[2]) cycle.
- the sign-of-life (p2045) has not been correctly interconnected (r2050[3]).
The OK status can be identified on a SERVO drive object if the drive increments the slave sign-of-life (r2053[3].12-
15).
Re r2054 = 4:
In the status 4 (LED green), the cyclic connection to the PROFIBUS master has been established and setpoints are
being received. The clock cycle synchronization is OK - sign-of-life characters are being received and sent at all
SERVO drive objects.
