PROFIBus Master Diagnostics

Operator Menu Location: Generic Hardware Operators -> Networking -> PROFIBus

Operator Bitmap

Functional Description*:*
The operator issues a diagnostic check from the master.

Output pins indicate whether the master has a configured slave and whether the master is communicating with its slave.
[0] -> true if master has configured slave
[1] -> true if master is exchanging data with slave
[2] -> state output (see DPM_State below)
[3] -> remote error address (see Err_Rem_addr below)
[4] -> error event code (see page 25-26 of master document for error code interpretation)
[5] -> global error byte (see below)

[6] -> hard bus error count
The following error numbers are valid for Err_event, if Err_rem_adr is
255. Their format is;

CODE & EXPLANATION	ERROR SOURCE	REMEDY
0		no mistakes appear
50 USR_INTF-Task not found	DEVICE	contact technical support
51 no global data-field	DEVICE	contact technical support
52 FDL-Task not found	DEVICE	contact technical support
53 PLC-Task not found	DEVICE	contact technical support
54 non existing master parameters	DEVICE	execute download of data base again
55 faulty parameter-value in the master parameters	project planning	contact technical support
56 non existing slave parameters	project planning	execute download of data base again
57 faulty parameter-value in a slave parameters datafile	project planning	contact technical support
58 double slave address	project planning	check projected addresses
59 projected send process data offset address of a participant outside the allowable border of 0- 255	project planning	check projected addresses
60 projected receive process data offset address of a participant outside the allowable border of 0- 255	project planning	check projected addresses
61 data-areas of slaves are overlapping in the send process data	project planning	check projected addresses
62 data-areas of slaves overlapping in the receive process data	project planning	check projected addresses
63 unknown process data handshake	warmstart	check warmstart parameters
64 free RAM exeeded	DEVICE	contact technical support
65 faulty slave parameter data sets	project planning	contact technical support
202 no segment for the treatment free	DEVICE	contact technical support
212 faulty reading of a data base	DEVICE	execute download of data base again
213 structure-surrender to operating system faulty	DEVICE	contact technical support
220 Software Watchdog error	HOST	check HOST program Controlled Start and Stop of I/O Connection 25
221 No Data Acknowlegde in process data handshake mode 0	HOST	program hasn't acknowledged the last handshake in time
222 Master in Auto_Clear	Slave Device	the auto_clear mode was activated, because one slave is missing during runtime
225 No further Segments	DEVICE	contact technical support

The following error numbers are valid for Err_event, if Err_rem_adr is unequal 255:

CODE & EXPLANATION	ERROR SOURCE	REMEDY
2 station reports overflow master	telegram	check length of configured slave configuration or parameter data.
3 request function of master is not activated in the station master	telegram	check slave if PROFIBUS-DP norm compatible
9 no answer-data, although the slave must reponse with data	slave	check configuration data of the station and compare it with the physical I/O data length
17 no response of the station	slave	check bus cable, check bus address of slave
18 master not into the logical token ring	DEVICE	check FDL-Address of master or highest-station-Address of other master systems. examine bus cableing to bus short circuits.
21 faulty parameter in request master	telegram	contact hotline
