380005 Profibus-DP: bus %3 access conflict, type %1, counter %2
Parameters: %1 = Conflict type
%2 = Serial number within a conflict sequence
%3 = Number of the affected bus
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 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 on the next conflict.
Reaction: Alarm display.
Remedy: - Check the timing again, in particular ensure that the settings in SYSCLOCK_CYCLE_TIME and
POSCTRL_CYCLE_DELAY are correct: POSCTRL_CYCLE_DELAY must be larger for type 1.
POSCTRL_CYCLE_DELAY must be smaller for type 2.
- If alarm-free operation cannot be achieved with any POSCTRL_CYCLE_DELAY setting,
SYSCLOCK_CYCLE_TIME must be increased.
- If the error cannot be eliminated by this procedure, please make a note of the error text and contact
the control system manufacturer.
Program Clear alarm with the Delete key or NC START.
Continuation:
380020 PROFIBUS DP: bus %3 SDB %4 error %1 source %2
Parameters: %1 = Error
%2 = SDB source
%3 = Bus number
%4 = SDB number
Definitions: Error in SDB for configuring PROFIBUS DP.
Causes of the error:
- 01 = SDB does not exist in source.
- 02 = SDB from source is too large.
- 03 = SDB from source cannot be activated.
- 04 = source is empty.
- 05 = source is not present.
SDB source:
- 99 = passive file system: _N_SDB_DIR
- 100 = CF card: /siemens/sinumerik/sdb/...
- 101 = CF card: /addon/sinumerik/sdb/...
- 102 = CF card: /oem/sinumerik/sdb/...
- 103 = CF card: /user/sinumerik/sdb/...
Reaction: PROFIBUS DP is inactive or working with default SDB.
Reaction: Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
Remedy: - Check the setting of MD 11240.
- If source = 100: Check directory _N_SDB_DIR in the passive file system.
- If source = 103-106: Check directories on CF card
Program Switch control OFF - ON.
