Sinumerik Alarm 380005 Profibus-DP: bus access conflict, type %1, counter %2
%1 = Conflict type
%2 = Serial number within a conflict sequence
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.
– Alarm display.
• 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 set- ting, 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.
Clear alarm with the Delete key or NC START.
