PROFIBUS Power Hub Segment Coupler 3 (SK3)
Operation
PA Bus Configuration + Diag. :
■
• Watchdog time
• PA retry limits
• Number of activated PA segments
• Diagnostics (ADM alarm observer)
If the PA bus configuration module is set, values that are set with this module cannot be
changed with acyclic access during cyclic communication.
Diagnostics (Slave Diagnostics)
The BIS returns the following of the diagnostic blocks described in the GSD file:
Device diagnostics
■
0 ... 4 x segment diagnostics (channel diagnostics)
■
RedState data block
■
Device diagnostics provides specific diagnostic information on the gateway. This information is
parsed directly by the process control system and displayed for the user. In redundant
configuration, all diagnostic information is also available for the redundancy partner. Device
diagnostics includes:
Device Diagnostic Parameters
Gateway primary device
Redundancy not operative
Redundancy is synchronizing
Redundancy gateway missing
Hardware error detected
Redundancy link error
No baud rate detected
Built-in slave not in data exchange
Firmware version mismatch
Firmware updated, need reboot
A PA master not in token ring
PA bus parameters write locked
Segment MAU error
ADM error or module missing
ADM system maintenance required
ADM system out of specification
ADM segment maintenance required
ADM segment out of specification
All device diagnostic parameters marked with "Yes" in the EXT_DIAG column cause the
EXT_DIAG to be set in the slave diagnostics. The process control system then marks that slave
as defective. Channel diagnostics returns specific diagnostic information on each individual
segment. These error messages are prioritized and set to preferred by the BIS depending on
their ranking. The following table represents diagnostic information according to its ranking.
