SINUMERIK 802D sl, Diagnostics Manual, 06/2007 Edition

2.3 Profibus alarms

380001 Profibus-DP: startup error, reason %1 parameter %2 %3 %4.

Parameters: %1 = cause of error

%2 = parameter 1

%3 = parameter 2

%4 = parameter 3

Definitions: An error occurred during startup of the DP master.

Reaction: Channel not ready.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

Remedy: Please proceed as follows:

Check the control project (particularly SDB); check MD 11240; if a user-specific SDB is in use, load it

again.

If the error still exists, save the file and restart the control system using the default values with which

the system was supplied.

If the system starts up without an error, the user data should be loaded one step at a time.

If the error still exists after startup with the default values, reboot from the PC card or update the soft-

ware.

If the error still exists, replace the hardware. If the error cannot be eliminated by this procedure, please

make a note of the error text and contact the control system manufacturer.

Program Con-

tinuation:

Switch control OFF - ON.

380003 Profibus-DP: operating error, reason %1, parameter %2 %3 %4.

Parameters: %1 = cause of error

%2 = parameter 1

%3 = parameter 2

%4 = parameter 3

Definitions: An operating error occurred on the PROFIBUS DP in cyclic mode.

Reaction: Channel not ready.

NC Start disable in this channel.

Interface signals are set.

Alarm display.

Remedy: For error cause 01:

Check the electrical and fault-related specifications for PROFIBUS DP, assess the cable installation

Check the terminating resistors of the PROFIBUS connectors (CN setting at end of cable, otherwise

OFF setting required)

Check slave for error causes 02, 03, 04:

Check SDB for error causes 02, 03, 04, 05:

Follow the procedure described for troubleshooting alarm 380001

If the error cannot be eliminated by this procedure, please make a note of the error text and contact

the control system manufacturer.

Program Con-

tinuation:

Clear alarm with the RESET key. Restart part program

380005 Profibus-DP: bus %3 access conflict, type %1, counter %2

Parameters: %1 = conflict type

%2 = serial number within the conflict sequence

%3 = number of the bus affected

Definitions: An access conflict occurred on the PROFIBUS DP in cyclic mode: The NCK attempted to write data

to the bus or to read from the bus while cyclic data transfer was active. This can lead to data integrity

problems. Type 1: Cyclic transfer has not finished on the PROFIBUS when the NCK attempts to read

data Type 2. The NCK has not finished writing data when cyclic transfer begins again. Counter %2

contains a serial number starting at the number 1. A maximum of 10 alarms are output in succession.

If no conflicts occur in a DP cycle, the counter is reset and new alarms are output again during the

next conflict.

Reaction: Alarm display.

Remedy: Recheck timing conditions, correctly set SYSCLOCK_CYCLE_TIME and
