%2 = Parameter 1
%3 = Parameter 2
%4 = Parameter 3
Definitions: An operating error occurred on the PROFIBUS DP in cyclic mode.
Overview: Cause of the error, Par 1, Par 2, Par 3:
• 01 = unknown alarm, alarm class, logical address, --
• 02 = DPM cycle timeout, DPM actual value status, DPM setpoint value status, --
• 03 = DPM cycle status, DPM actual value status, DPM setpoint value status, DPM error
code
• 04 = DPM cycle error, DPM actual value status, DPM setpoint value status, DPM error
code
• 05 = client not registered, client number, max. number of clients, --
• 06 = synchronisation error, number of sync violation, --, --
• 07 = spinlock timeout, PLC spinlock, NCK spinlock
• Digit 1000 of the error cause = number of the affected bus
Alarm class: (see alarm 380 060)
The following can be primary causes:
• For error cause 01: Data transfer error on PROFIBUS DP
• For error cause 02, 03, 04: Error in contents of SDB1000
• For error cause 02, 03, 04, 05, 07: Corruption of parts of system program
• For error cause 06: The PCI bus cycle does not match the expected rate and synchroni-
zation is not possible for this reason. The correct PCI bus cycle must be entered.
The error can also be caused by a hardware problem on the MCI module.
Reactions: - 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 (ON setting at end of
cable, otherwise OFF setting required)
• Check slave
• For error cause 02, 03, 04:
• Check SDB1000
• For error cause 02, 03, 04, 05:
• Follow the procedure described for troubleshooting alarm 380 001
• For error cause 06:
• The correct PCI bus cycle must be entered.
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 a conflict sequence
%3 = Number of the affected bus
