6.  PROFIBUS TROUBLESHOOTING

The error messages, fault causes and remedial measures required are described in section 5. If communication
over the PROFIBUS link is not successful, check the causes listed for fault codes F030 and F033.

6.1  Diagnostic Parameters

The CB15/CB155 stores diagnostics information in a diagnostics buffer for installation and service purposes. The
diagnostics information can be read out with the indexed parameter P880.i (diagnostics).

The diagnostics buffer assignment on the CB15/CB155 is as follows:

P880.i

Meaning

P880.0

Counter: error-free message frames received

P880.1

P918 mirror (station address)

P880.2

No. of identification bytes received by master

P880.3

No. of PKW bytes

P880.4

No. of PZD bytes

P880.5

PPO Type

P880.6

Counter: FREEZE

P880.7

Counter: CLEAR_DATA

P880.8

Counter: SYNC

P880.9

Group identifier

P880.10

Watchdog

P880.11

Counter: watchdog timeout

P880.12

Address of PROFIBUS master

P880.13

Slave status

P880.14

Baud rate

P880.15

Warning bits
